Balloons in the Air: Understanding weather and climate
Dr. Ronan Connolly & Dr. Michael Connolly
Time: | |
00:00 | hi so for this talk myself and Michael |
00:05 | we'll be alternating between it to go |
00:09 | through different parts in this talk I |
00:11 | am but it's describing the work that |
00:13 | we've done together just to mention a |
00:15 | little bit of age |
00:17 | what we've done is from 2010 to 2014 |
00:22 | where we spent well five years working |
00:26 | looking at the data from weather |
00:29 | balloons which there is launched once to |
00:35 | four times a day around the world in a |
00:37 | beta deterrence stations around the |
00:39 | world and these go up into the |
00:41 | atmosphere and they record temperature |
00:43 | pressure and various stuff and so we |
00:46 | started doing analysis to see what's |
00:48 | happening in the atmosphere it is a data |
00:51 | going back to the 50s and we found a |
00:53 | load of different results and we |
00:56 | realized that there was a lot of |
00:58 | paradigms in current atmospheric |
01:01 | modeling that people had never tested |
01:06 | and we had so much we couldn't fit it |
01:09 | into one single peer-reviewed paper and |
01:11 | we decided look let's just put |
01:14 | everything up onto a website and put a |
01:18 | date for open peer review so we set up |
01:20 | the open peer-reviewed journal and most |
01:23 | of the work that we will be talking |
01:24 | about you can get on this and we'll talk |
01:27 | a little bit about some newer work in in |
01:31 | the future or towards the end of the |
01:33 | talk but the first part I'm going to |
01:35 | talk about the history of atmospheric |
01:37 | measurements then I'm gonna hand it over |
01:39 | to Michael who's my father and he's |
01:43 | going to talk about the work that I was |
01:45 | describing in the that you can get those |
01:47 | papers on the open peer-reviewed journal |
01:49 | and then finally we're just going to |
01:51 | present a sneak preview of some of the |
01:53 | newer work that we are preparing for |
01:56 | submitting to for peer review so what |
02:00 | I'd like you to get from from this first |
02:04 | part is that all of the models and most |
02:10 | of our understanding of what's happening |
02:12 | in the |
02:13 | atmosphere it's based on measurements |
02:15 | that were done on ground and this so |
02:20 | I'll give you example so this was one of |
02:23 | the first key discoveries which was well |
02:27 | Columbus use it's a great advantage in |
02:30 | that he found that I don't know if you |
02:34 | could see the the map on the thing where |
02:36 | you could see the voyages that were |
02:39 | drawn to the Americas and they found |
02:42 | that by going in a particular direction |
02:45 | go under going west and then East they |
02:48 | were able to take advantage of the |
02:50 | prevailing easterlies and westerlies and |
02:52 | that sped up the journey quite a bit so |
02:55 | this was like obviously a major |
02:57 | advantage so in the 1600 1700 to 1800 s |
03:01 | we had a lot of very prominent |
03:04 | scientists trying to figure out why why |
03:07 | are these prevailing winds there and |
03:10 | these of course were ground-based |
03:12 | measurements there were there real |
03:14 | measurements taken by explorers so you |
03:16 | have people like Hadley Holly of |
03:18 | Halley's Comet fame and Farrell |
03:21 | developing this the other method if you |
03:23 | want to find if you want to go up and |
03:27 | find what's happening higher up in the |
03:29 | atmosphere in the old days you had to |
03:31 | climb a mountain so you actually had |
03:35 | most of the meteorologists when they |
03:37 | wanted to look at what's happening up |
03:39 | would climb up mansions Mont Blanc in |
03:42 | Europe is the highest mountain in Europe |
03:44 | it's five kilometers of a tree three |
03:47 | miles above sea level one of the results |
03:50 | which most of us probably already know |
03:53 | is that as you go up in the atmosphere |
03:55 | it gets colder at height and the lapse |
03:59 | rate the rate which you do is it works |
04:03 | at about 6 and 1/2 degrees Celsius per |
04:05 | kilometer and here's another example |
04:08 | spectroscopy is looking at light and a |
04:13 | parody be I tried a lot of you would |
04:16 | probably be familiar with spectroscopy |
04:18 | but it's essentially you're looking at |
04:21 | the wavelengths of light and different |
04:24 | things and trying to infer in for my |
04:26 | Vitus so the ozone layer was first |
04:30 | identified by looking at air in the |
04:33 | early 20th century by looking at |
04:35 | spectrophotometers and looking at the |
04:38 | light that was coming through the |
04:41 | atmosphere and they noticed that there |
04:43 | were these Peaks are missing bits in the |
04:46 | spectra that were due to ozone and they |
04:50 | realized that ozone was existing |
04:53 | somewhere up in the atmosphere and it |
04:55 | was later identified it's been about 40 |
04:58 | kilometers up in the atmosphere is the |
05:00 | ozone layer another example that's quite |
05:04 | well-known it was by John Tyndall who |
05:07 | was an Irish man and so he must have |
05:10 | been good and so he showed that if you |
05:14 | look at the infrared light he found that |
05:19 | if you look in the atmosphere oxygen and |
05:22 | nitrogen are almost transparent to |
05:25 | infrared light but that water vapor co2 |
05:28 | and methane that they are infrared |
05:30 | active what we'd call infrared active |
05:32 | that means they can absorb and emit a |
05:34 | particular frequencies of IR and yes |
05:40 | well here we are 50 days if 50 years ago |
05:43 | today the the eagle was landing of |
05:49 | what's launched and I think I told of |
05:52 | the exact time I think it's supposed to |
05:54 | it landed as probably it tomorrow |
05:57 | morning or something like that and so |
06:01 | that was kind of the culmination of a in |
06:05 | many sense the space race and another |
06:08 | aspect of the space race was people |
06:10 | started launching satellites and in 1960 |
06:14 | the u.s. started the series of first |
06:17 | weather satellites were launched and |
06:20 | they're still running now we're on I did |
06:22 | the 45th Terra satellite at the moment |
06:26 | so what I just want to show you it's |
06:29 | great now with the space after the space |
06:32 | race we now are able to look from above |
06:34 | the atmosphere but here's what's |
06:37 | happening you know most of our |
06:40 | measurements were done from below the |
06:41 | atmosphere now we're looking at it from |
06:43 | above the atmosphere and if you want to |
06:47 | look at what's inside the atmosphere |
06:49 | that's if you want to understand what's |
06:51 | happening you need to look within the |
06:52 | atmosphere and on the main data set that |
06:55 | you can do is weather balloons so this |
06:59 | has a history going back to the early |
07:01 | late 19th century even earlier but we |
07:05 | had it just on the cusp of the earlier |
07:09 | of the 19 - 20 th century we had a |
07:11 | number of European groups that well |
07:13 | started using both manned and unmanned |
07:17 | weather balloons now I liked I found |
07:20 | this nice drawing by from one of the the |
07:24 | pilots for the German group that was |
07:30 | also a an artist and so he's the guy on |
07:34 | the right holding that bike yellow and |
07:37 | that was Hans gross but he drew that |
07:40 | this painting of what it was like a few |
07:43 | years after he had been in it but |
07:46 | independently about the French group |
07:48 | where it was just using online balloons |
07:51 | and the German group in 1902 they |
07:53 | discovered what we now call the |
07:55 | tropopause though they initially called |
07:58 | it the stratosphere and so what was this |
08:01 | trap a pause stratosphere well you know |
08:03 | as I mentioned earlier on as you go up |
08:05 | in the atmosphere gets colder with |
08:08 | height but they were discovering this |
08:10 | odd phenomenon where it starts to |
08:13 | actually remain constant with height you |
08:16 | go up and it doesn't get colder and |
08:18 | later on it was discovered there was |
08:21 | another region where as you go even |
08:22 | further it starts getting hotter with |
08:25 | height and this was a major puzzle and I |
08:30 | yeah so the the logic all don't from |
08:34 | ground without measurements was that |
08:36 | they were saying well you know hot air |
08:39 | rises I so all else being equal and so |
08:42 | he said well if the temperature is not |
08:45 | getting colder with height you can't |
08:47 | have circulation and so they assumed |
08:50 | must be that the air is stratified |
08:53 | - non mixing layers they didn't actually |
08:56 | notice they weren't measuring her but |
08:58 | they juices an assumption they made and |
08:59 | that's why the name stratosphere came |
09:02 | from that the air was stratified and |
09:04 | they said where is trap us turning or |
09:07 | mixing the troposphere they is mixed so |
09:10 | that was just a ground-based assumption |
09:14 | looking at these fairly weather balloon |
09:16 | models and we can see as you go up in |
09:20 | the atmosphere we now know looking at |
09:22 | using rockets and that you can see that |
09:26 | as you go up even higher the |
09:28 | stratosphere starts to pause again and |
09:31 | then it starts to decrease with height |
09:33 | again then we get another thing we say |
09:36 | we have this back and forth and if you |
09:39 | see a shooting star it's probably in a |
09:42 | random eases fear me suppose region but |
09:46 | for the rest of the talk we're just |
09:48 | gonna focus on the lower tree regions |
09:51 | you see the stratosphere troppo pause |
09:54 | and troposphere and that's the region |
09:56 | that the balloons go up to 35 kilometers |
09:59 | right 20 22 miles or something yeah and |
10:03 | that in terms of the mass of the |
10:06 | atmosphere that comprises 99% of the air |
10:11 | mass so it's the bulk of the mass and |
10:15 | yeah I you yeah so we just the old days |
10:21 | the early balloons they used to put a |
10:25 | little removed a balloon burst it could |
10:28 | land like 200 miles away from where it |
10:31 | was launched so in order to get the data |
10:33 | back they will put a little reward sign |
10:36 | note in with the measurements and saying |
10:39 | if found please return to the |
10:41 | meteorological observatory and you'll |
10:43 | get the equivalent of probably like 20 |
10:46 | dollars or something like that but then |
10:48 | in the thirties they invented a radio |
10:51 | transmitters got so cheap that it didn't |
10:54 | became standard so now you'll hear the |
10:57 | term radiosonde used for a weather |
11:00 | balloon sounding sound for sounding and |
11:04 | it was the name came from the |
11:06 | the nautical term where people would |
11:08 | troll a the arduous sounding going down |
11:12 | into the ocean and they said well we're |
11:13 | kind of doing the reverse doing a |
11:16 | sounding going vertically so what in |
11:22 | terms of the development of our |
11:24 | understanding of the current textbook |
11:27 | understanding of climate and atmosphere |
11:29 | there were two main puzzles that were |
11:32 | captivating scientists in the early |
11:35 | night early 20th late nineteenth century |
11:38 | why order ice ages that was the first |
11:41 | one at this stage they already knew that |
11:45 | most have been at least four periods in |
11:48 | the last million years and we now know |
11:50 | there was there's more it's roughly by |
11:52 | ten where the France |
11:57 | yeah Europe and Americas were covered |
12:01 | with glaciers almost covered and then |
12:04 | into a what we now called an integration |
12:07 | period like today where that's not the |
12:09 | case so they wanted to know why did that |
12:11 | happen |
12:12 | the other one was this new discovery of |
12:14 | a trump upon stratosphere under like |
12:16 | what's happening here and because the |
12:21 | ozone layer was discovered around the |
12:23 | same time around 1912 the assumption was |
12:28 | it's probably something to do with the |
12:31 | ozone layer people that are familiar |
12:36 | with the climate change debate now |
12:38 | you'll you might recognize that a lot of |
12:41 | the topics of the theories that people |
12:43 | were proposing for explaining the ice |
12:46 | age non-ace H are still the main topics |
12:51 | of people are doing here changes in |
12:53 | solar variability the Earth's orbit |
12:56 | changes in water cloud cover |
12:58 | co2 volcanic eruptions I the I just |
13:03 | checked it's interesting I was just |
13:04 | talking about on on the next slide but |
13:06 | in the late 19th century one of the |
13:08 | prior the main ones that was being |
13:11 | proposed was that co2 was responsible |
13:13 | for all of the Earth's climate change |
13:16 | and including the ice ages |
13:19 | then nowadays the prevailing consensus |
13:23 | by the IPCC and others is that oh no the |
13:26 | ice ages are due to the Milankovitch |
13:30 | cycles changes in the Earth's orbit but |
13:33 | we are still holding on to this notion |
13:36 | that co2 is dominant for short term a |
13:40 | climate changes so we Michael will talk |
13:43 | a little bit about that later on in his |
13:45 | section but you could just say show you |
13:47 | a lot of people often hear of svante |
13:49 | arrhenius or in the nineteenth century |
13:52 | they already have proved that co2 was |
13:54 | the driver of climate well in the night |
13:58 | Jade said air debate few years later |
14:00 | he's a Swedish colleague contemporary |
14:05 | Noah angstrom who was the son of Anders |
14:08 | angstrom that's the unit is named after |
14:10 | angstrom is named after he went had read |
14:13 | the papers and decided to do experiments |
14:16 | did one of the first systematic reviews |
14:19 | of the IR spectrum of co2 and his |
14:23 | results were saying no co2 was not the |
14:26 | driver George Simpson is a very |
14:30 | interesting guy he was one of the |
14:33 | surviving members of Scott of Antarctic |
14:36 | expedition so he was the meteorological |
14:40 | scientist so he stayed at the base camp |
14:43 | so like many of you will are probably |
14:46 | familiar with jazz |
14:48 | Robert Scott's Antarctic tragic |
14:50 | expedition they got to the South Pole a |
14:53 | few days shortly after Raul Amundsen but |
14:58 | then they they died on the way back but |
15:01 | because George Simpson was still at |
15:03 | Basecamp he survived he later went on to |
15:06 | have a very prestigious career director |
15:08 | at British Meteorological Office he was |
15:11 | knighted and whatever reason that I'm |
15:15 | mentioning it here is in the twenties |
15:16 | and thirties he we looked at both of |
15:18 | those two puzzles and he was using |
15:21 | because he was in a meteorological thing |
15:23 | he had access to all the weather |
15:25 | balloons when he did his analysis his |
15:27 | calculations he concluded co2 was not |
15:30 | the driver of the ice |
15:33 | of climate change he was very |
15:35 | categorical about that they said |
15:38 | temperatures in the troposphere were not |
15:42 | driven by radiative processes which I'll |
15:47 | talk a bit about later and he said and |
15:49 | probably convection was more important |
15:52 | but he argued that the stratosphere his |
15:55 | calculations may be radiation was |
15:57 | involved said is probably something to |
15:59 | do with ozone but he put in two caveats |
16:01 | that there was a lot of inconsistencies |
16:03 | with the theory and the data which |
16:06 | Michael will talk about later on most of |
16:09 | this work was done with very high de |
16:13 | without computers are before with very |
16:15 | early computers and so you were very |
16:18 | limited in what you could do so a |
16:20 | philosophy that seems to been popular |
16:22 | was the peak wanting approach so Gilbert |
16:26 | plus he explicitly stated one of his |
16:29 | papers he was going to try and explain |
16:31 | every possible climate change that |
16:33 | occurred in terms of co2 and his logic |
16:36 | was he said well presumably somebody |
16:39 | else will try and look at other factors |
16:41 | and whatever the truth is between at all |
16:44 | will eventually get to the truth but it |
16:46 | seems that plus nobody else took him up |
16:50 | on that offer and sell a lot of these |
16:52 | say a deteriorate co2 as the driver |
16:55 | relates back to plus and those papers |
16:58 | else a sir he went and he tried to |
17:04 | describe the entire atmospheric |
17:06 | temperature profile using radiative |
17:08 | process is ignoring convection or |
17:11 | anything like that but just using |
17:12 | radiative processes and the |
17:14 | interestingly this was a puzzle because |
17:16 | we he keeps referring to what Einstein |
17:19 | had found in the photoelectric effect |
17:21 | but there's the mention there is no |
17:25 | mention of the name Einstein in his 1942 |
17:30 | Harvard monograph and this we were kind |
17:32 | of looking at a Michael pointed H oh |
17:35 | that you know that Einstein was in |
17:38 | Princeton at the time so you couldn't |
17:41 | mention in a Harvard monograph the he |
17:43 | Princeton professor |
17:47 | so you'll see a lot of people referring |
17:49 | to Kirchhoff's laws in when they're |
17:52 | using climate modeling and they're |
17:54 | actually referring to Einsteins laws but |
17:57 | they're using else a sirs book which |
17:59 | rebranded Einstein as Gustav Kirchhoff |
18:03 | had discovered everything was so man |
18:05 | abeyance trickler who they went on that |
18:10 | what later became Noah G FTL's |
18:12 | Princeton ironically Princeton crop' in |
18:16 | a climate modeling group they tried to |
18:19 | use else Asura's data in the sixties to |
18:23 | explain the entire tropopause |
18:25 | stratosphere and troposphere in terms of |
18:28 | radiative processes but there was a big |
18:31 | problem remember I said that the lapse |
18:33 | rate was six and a half degrees per |
18:36 | Celsius per kilometer in the troposphere |
18:39 | when they did their calculations they |
18:42 | kept getting -16 nearly three times the |
18:46 | rate of cooling and they also were |
18:50 | calculating that the ground temperature |
18:53 | was of the order of 160 fahrenheit now I |
18:58 | I'm coming from Ireland so when I |
19:00 | arrived here in Tucson it did feel a |
19:03 | little like that but I think maybe not |
19:05 | that high and so I they did find out |
19:11 | that this stratosphere |
19:12 | kind of looks about right and so George |
19:16 | Simpson that I mentioned earlier the guy |
19:19 | in scott of Antarctica's group he he had |
19:23 | looked did similar calculations that |
19:25 | he'd concluded well clearly the |
19:27 | troposphere is not dominated by the |
19:29 | radiative presses and that's what he was |
19:31 | saying is probably convection mono Bay |
19:33 | and Strickler went a different route |
19:35 | they said so let's just keep adjusting |
19:37 | our models and so what they do is they |
19:41 | would put in a an arbitrary if they |
19:44 | found a lapse rate was getting too high |
19:46 | a rapid after it in during the |
19:50 | simulation they would just artificially |
19:52 | put in a thing to shove the data at |
19:55 | their model thing back so didn't matches |
19:57 | two minus six and a half |
19:59 | they didn't really they said well it's |
20:01 | probably something to do with convection |
20:03 | so it's called the convective adjustment |
20:05 | and the Apollo mission used the IBM 7090 |
20:13 | supercomputer and I was incredibly |
20:17 | advanced of course now you have a |
20:20 | smartphone is the only thing that as |
20:23 | everything has gotten bigger with this |
20:24 | rifle the CPU the round the only thing |
20:26 | that's gotten smaller is the size so and |
20:30 | so you would say yes so we've had |
20:33 | massive improvements in the |
20:34 | supercomputers but what have they done |
20:37 | with it climate modelers have improved a |
20:40 | resolution and they've added in extra |
20:43 | components to these two schematics by |
20:45 | the way that you could see under saying |
20:47 | are taken from the IPCC fourth |
20:49 | assessment report this is their own |
20:51 | description the IPC's description of how |
20:54 | climate models have advanced what I want |
20:57 | to point out is that the fundamental |
20:59 | what's called the physics in the jargon |
21:03 | is what they'll use is that doubt that |
21:06 | radiatively dominated was the main |
21:08 | driver that was never checked and they |
21:11 | just keep on using that and the |
21:14 | implications well if the atmosphere is |
21:18 | dominated temperature profile is |
21:19 | dominated by radiative processes well as |
21:24 | Tyndall had shown it co2 and water vapor |
21:28 | on me chain and ozone are the key |
21:31 | components there and so they they said |
21:34 | well if you increase co2 which we now |
21:38 | know is occurring you know Don Manoel |
21:40 | our shows that it has increased then |
21:44 | they predicted so you will get global |
21:47 | warming and they were predicting this in |
21:49 | the 60s manna Bay in wet around 1967 I |
21:52 | think was the first to its will |
21:54 | compliant computer model to make that |
21:56 | prediction and where some other ones a |
21:59 | earlier on but like it was the problem |
22:04 | was that at the time it was global |
22:06 | cooling was occurring from the 40s to |
22:09 | the 70s and so that was a big crowd |
22:13 | but then in the 80s it started warming |
22:15 | again and so the climate modelers |
22:17 | declared vindication and famously a |
22:20 | particular James Hansen and a NASA |
22:23 | modeling group he wedged and testified |
22:27 | for out towards Al Gore and he's as a |
22:31 | result yeah |
22:33 | the greenhouse effect enhanced |
22:36 | greenhouse effect Harry became |
22:38 | mainstream was reported around the world |
22:40 | it led to the setting up of the IPCC the |
22:44 | UN also the UN cop agreement Sola Rosa |
22:48 | where people are trying to cut down co2 |
22:51 | emissions and have international |
22:53 | negotiations to do that that all went on |
22:57 | in parallel to while the UN was trying |
23:01 | to negotiate all of these agreements and |
23:04 | the Paris 2015 agreement comes from that |
23:07 | line of the UN the IPCC was supposed to |
23:11 | actually go and check the results but |
23:13 | they'd already decided in 1988 that the |
23:18 | science were settled apparently just |
23:22 | what you end this first part by pointing |
23:24 | out that his quote artists Fame aligned |
23:27 | from Joni Mitchell sang and I think to |
23:29 | do the analogy to paraphrase that people |
23:33 | you know we have looked at the |
23:36 | atmosphere from both sides now from |
23:38 | above the atmosphere and below the |
23:41 | atmosphere but a little you actually |
23:43 | look in the atmosphere you don't really |
23:47 | know what's happening and I'll now hand |
23:50 | over to Michael |
23:56 | I'm just going to briefly summarize the |
23:59 | scientific method because this is what |
24:02 | we use when we're analyzing the weather |
24:04 | balloons we don't use models around like |
24:06 | that and we don't adjust the data we |
24:08 | just use this particular method so |
24:10 | basically what a scientist does is he'll |
24:12 | do a set of experiments we collect a |
24:14 | whole big pile of data and make |
24:16 | observations so we call these facts and |
24:19 | then if he can come up with an equation |
24:21 | that will describe all this set of data |
24:23 | then these are called laws but if you |
24:26 | come up with something new I scientists |
24:29 | really wants to explain why is it |
24:31 | happening laws tell you what happens and |
24:33 | how they happen but they don't tell you |
24:35 | why so the first thing you do then is |
24:37 | you make a guess as to why it happens |
24:40 | and we call this a hypothesis and this |
24:42 | is where the scientific method comes in |
24:44 | because what as a scientist you're Danah |
24:47 | obliged to put your guess to all of the |
24:51 | tests than you can think of and maybe |
24:53 | get other people to come up with other |
24:54 | tests and what happens is if it survives |
24:57 | all the tests then you have a theory and |
25:01 | but the unfortunate thing is if if any |
25:05 | facts are not explained by your guests |
25:08 | or your hypothesis then it's wrong so |
25:12 | that's what summed up by famously by |
25:16 | Richard Feynman where he said it doesn't |
25:18 | matter how smart a person is it doesn't |
25:20 | matter how beautiful the hypothesis is |
25:23 | one ugly fact that disagrees was it |
25:26 | destroys the whole thing so the other |
25:30 | thing is that if you have two or more |
25:32 | theories that explain all the facts then |
25:34 | what we use is the principle of Occam's |
25:36 | razor who was an 11th century monk and |
25:38 | he said if two or more theories explain |
25:40 | all the facts pick the simplest one so |
25:43 | that basically is the scientific method |
25:45 | in a nutshell now let's have a look at |
25:48 | the weather balloon data this is typical |
25:51 | weather balloon and attached onto the |
25:53 | bottom of it there you'll see the little |
25:55 | instrument package which measures the |
25:57 | temperatures and so on |
25:59 | and what do you get from this weather |
26:01 | balloon the weather balloon now adays |
26:03 | they're filled with hydrogen or helium |
26:05 | and they go up to about 25 miles |
26:09 | then they burst and all the way up there |
26:11 | sending back all the disinformation it |
26:13 | takes about 90 minutes for it to get to |
26:15 | 25 miles or so and this is what you'll |
26:19 | get back a whole list of data now this |
26:21 | is only about a third of the data but it |
26:23 | gets the point across and what you can |
26:25 | see is that there are temperature |
26:27 | measurements pressure measurements and |
26:30 | so on and then there are certain levels |
26:33 | called mandated pressure levels which |
26:35 | I've underlined some of them they're the |
26:37 | ones on this section in red and they're |
26:40 | obliged to take those measurements |
26:42 | regardless so what do you get when you |
26:45 | have your weather balloon data well here |
26:48 | I've taken the weather balloon data from |
26:51 | this day last year in Tucson and also |
26:55 | one on the first of January for this |
26:56 | year in Tucson and I've plotted here the |
26:59 | temperature versus the the height or the |
27:05 | pressure as you go up so down the green |
27:07 | bit down there represents the ground and |
27:09 | the top scale across there is in degrees |
27:12 | Kelvin which is the scientifically used |
27:15 | temperature it's zero degrees centigrade |
27:19 | or 32 degrees Fahrenheit this 273 |
27:22 | degrees Kelvin so you can see on the |
27:25 | Tucson one there the temperature is |
27:28 | about 31 32 that would be or sorry 310 |
27:33 | or something like that that would be |
27:35 | about 40 degrees centigrade or 107 |
27:38 | Fahrenheit so I just picked the January |
27:43 | and July one one is in the evening of |
27:45 | one is in the morning for to illustrate |
27:48 | the difference between summer and winter |
27:51 | and day and night and before I can start |
27:54 | showing you how we analyze that I have |
27:56 | to summarize the gas laws I'm sorry to |
27:59 | have to bore you with this but I know |
28:01 | most of you may have forgotten most of |
28:03 | them so this is a quick summary Boyle |
28:06 | who again was another Irishman and had |
28:08 | to be write as well he he said that if |
28:12 | you increase the pressure on the gas it |
28:15 | gets smaller so if you double the |
28:18 | pressure you have the volume if you have |
28:20 | the pressure you get the ball you |
28:23 | with double the volume and then you had |
28:25 | Charles the slow who was in a French man |
28:30 | and he was the first guy to ever man a |
28:33 | balloon so he's the first month flush in |
28:38 | a balloon he said if you heat a gas it |
28:40 | expands and if you cool the gas it's |
28:43 | easier to squeeze it back down into a |
28:45 | small volume again and the last law that |
28:48 | we have in the gas laws is Avogadro's |
28:50 | law and he just simply said that if you |
28:54 | have two gases occupying the same volume |
28:57 | it doesn't matter what the gases are one |
29:00 | could be hydrogen a very light gas the |
29:02 | other might be carbon dioxide which is a |
29:04 | lot heavier and made up of three atoms |
29:06 | the type of atoms or molecules doesn't |
29:10 | matter all that matters is that they |
29:12 | have the same number of molecules in the |
29:16 | gas if they occupy the same volume they |
29:18 | have the same number and we measured |
29:21 | count the number of molecules in a unit |
29:23 | called moles a mole is a very large |
29:26 | number there it's six by ten to the 23 |
29:29 | and in honor of abogado it's called |
29:32 | Avogadro's numbers so n therefore is the |
29:36 | number of moles that you would have in |
29:38 | the cubic meter of air so if you combine |
29:42 | those three gases together are those |
29:44 | three gas laws together you guys what's |
29:46 | called the ideal gas law and the |
29:49 | internal dynamics this represents the |
29:51 | equation of state of the ideal gas so |
29:54 | basically in terms of dynamics if if a |
29:58 | gas is obeying the gas law it's said to |
30:01 | be in thermodynamic equilibrium and this |
30:03 | would be an important point that we'll |
30:05 | get to later on so you can rearrange the |
30:10 | gas law or the equation of state into |
30:12 | the molar density form and what you'll |
30:15 | see then is you get D which is n over P |
30:20 | the number of moles per unit volume or |
30:22 | per square meter cubic meter that's |
30:26 | what it tells you is that if D is very |
30:29 | low the molecules are spread far apart |
30:31 | and if D is very high the molecules are |
30:35 | squashed close together so how does this |
30:39 | allow us to analyze the weather balloon |
30:42 | data well the first thing I'll tell you |
30:44 | is nobody I know of on to myself and |
30:48 | Ronin have analyzed the weather balloon |
30:50 | data in terms of D the molar density |
30:53 | even though it is an equation of state |
30:57 | it's just representing the same one in a |
30:59 | slightly different form but nobody |
31:01 | taught to analyze the data in this |
31:04 | particular way and the reason why this |
31:09 | is of use is that if you take this |
31:11 | January profile here and look at how the |
31:13 | temperature is changing as you go up |
31:15 | through the atmosphere it's fairly |
31:16 | wobbling back and forth and so on but if |
31:19 | I transfer that data and represent it in |
31:22 | terms of molar density what I end up |
31:25 | with is two straight lines and this is |
31:27 | what's quite a surprise and just to show |
31:31 | you that these really are straight lines |
31:33 | you can see the little circles represent |
31:36 | the actual measurements and if you look |
31:39 | at the correlation it shows it's |
31:42 | extremely good at the r-squared factor |
31:44 | if it's one it means it's a perfect |
31:46 | straight line if it's zero there's no |
31:48 | linear correlation at all but these |
31:50 | these started things are quite good now |
31:53 | the thing is that that one was one taken |
31:58 | in the evening hour sorry taken in the |
32:00 | morning what we find is if you take it |
32:03 | you're in the day after the Sun has |
32:05 | heated up the ground level is |
32:07 | represented by a third line but the |
32:10 | interesting and I get into that a bit |
32:12 | later the interesting thing is that we |
32:15 | can now find that we can divide the |
32:17 | atmosphere into three different regions |
32:20 | and each of these have their own staff |
32:24 | at a separate equation of state so that |
32:26 | means within each of these regions the |
32:28 | air is in term of dynamic equilibrium |
32:30 | and that will have implications that are |
32:33 | get into later and the other thing is |
32:35 | that at night when the sun goes down you |
32:37 | lose that bottom |
32:39 | and it just becomes the same as the rest |
32:41 | of the tropopause |
32:42 | so we analyzed all of the 20 million |
32:45 | radio songs that have been launched |
32:48 | since the 1950s I spent over an hour |
32:51 | counting him we found that there were |
32:54 | the same thing applied to all 20 million |
32:57 | there was two day reader represented by |
33:00 | two straight lines or three straight |
33:02 | lines depending on where the rose day or |
33:04 | night and to show that this wasn't just |
33:07 | cherry picking - what I have done is we |
33:11 | did the video for all of the radio songs |
33:14 | for Tucson here for last year and what |
33:19 | you can see here again as the vertical |
33:22 | axis is the term pressure you're going |
33:24 | from the ground upwards but the thing I |
33:26 | want you to take away from this is that |
33:27 | if you look at the right hand side I |
33:29 | fetched it just need to nitrate once I |
33:32 | didn't bother with the day once because |
33:33 | it would have been wiggling back and |
33:34 | forward a bit but if you look there you |
33:36 | can see that all of the the weather |
33:40 | balloon dieters are all fitted by the |
33:42 | same two straight lines but the |
33:44 | interesting thing is the horizontal line |
33:47 | shows for these two lines intersects and |
33:49 | that's the start of the tropopause every |
33:52 | single time and thing about it is as |
33:55 | jumps up and down it can jump up by boat |
33:57 | and down by as much as 20 percent of the |
34:00 | atmosphere in as little as 12 hours it's |
34:02 | a very rapidly changing phenomenon which |
34:05 | has a lot of implications so if we get |
34:07 | into later |
34:08 | so just to continually explanation then |
34:11 | I I just want to rotate the dis graph by |
34:16 | 90 degrees so that the ground is on the |
34:20 | right-hand side and the pressure is on |
34:24 | the bottom and the molar density is the |
34:25 | vertical axis so that's what I'm doing |
34:28 | here |
34:28 | and the reason I do this is that as |
34:30 | chemists it's quite common for us to |
34:32 | want to measure how the molar density |
34:35 | behaves with with pressure because it |
34:37 | tells us something about the |
34:38 | compressibility of a gas so normally you |
34:42 | take an ideal gas and by the way under |
34:44 | the conditions that we have in the |
34:45 | atmosphere oxygen hydrogen carbon |
34:48 | dioxide meter and they are all ideal |
34:51 | gases |
34:51 | so under |
34:53 | circumstance and water vapor is an ideal |
34:55 | gas provided the humidity is less than |
34:58 | 100 but if you increase the humidity |
35:01 | above a hundred then it ceases to be an |
35:03 | ideal gas that's just a side effect so |
35:07 | the thing about a gas is the more |
35:10 | compressible it is the easier it is to |
35:12 | squeeze it down this the flatter the |
35:15 | slope would be so you can see here the |
35:18 | red data points showing if are the |
35:20 | troposphere the lower section of the |
35:22 | atmosphere the gas has a certain |
35:25 | compressibility and then when it hits |
35:27 | the tropopause for some reason the gas |
35:30 | becomes easier to compress now this |
35:33 | turns out to be a killer blow for the |
35:36 | ozone heating hypothesis which I'll |
35:38 | explain why in a minute |
35:41 | to demonstrate this in a slightly |
35:45 | different way here we have the two songs |
35:48 | that I showed earlier I've put the |
35:49 | temperatures on top of each other so the |
35:52 | red one represents the summer |
35:54 | temperature for this day last year in |
35:56 | Tucson and the blue one represents the |
36:00 | are is the temperature for the winter |
36:04 | night one and when you look at the molar |
36:07 | density one you can see yes we get the |
36:09 | straight lines it's turned into straight |
36:11 | lines and you can see that the slope of |
36:14 | the red one the hotter one is less than |
36:16 | the slope of the green one are the blue |
36:19 | one the the colder one and this is |
36:22 | exactly what you would expect from |
36:24 | Charles's law if you put more energy |
36:26 | into the gas it becomes harder to |
36:28 | compress and the slope becomes less and |
36:31 | I can show you this again just on a day |
36:34 | night one this was the same one taken in |
36:36 | January I had ended it in the morning on |
36:40 | a tonight and what you can see here is |
36:42 | that journaling today the ground-level |
36:44 | heats up but at night it cools down but |
36:48 | the rest of the troposphere doesn't |
36:51 | change temperature this is a quite a |
36:53 | surprise and I nobody seems to a father |
36:56 | looking at this until now so these are |
37:00 | the different models that they had for |
37:03 | the tropopause that was come up by the |
37:06 | American atmospheric standards in 1972 |
37:10 | but I just show what the problems is |
37:14 | with the with the the thing is maybe I |
37:20 | didn't I skipped the point at this slide |
37:24 | here you can see that if you heat the |
37:26 | gas it becomes more compressible except |
37:29 | in the tropicals where the slope is much |
37:32 | bigger it's about 50% bigger so this is |
37:37 | why the ozone hypothesis heating |
37:40 | hypothesis fails because if it was |
37:42 | heating the tropopause it will become |
37:44 | harder to compress the slope should have |
37:46 | gone the other way |
37:47 | it shouldn't have got steeper it should |
37:49 | have got less so because that is not |
37:51 | what happens that's why the ozone |
37:53 | hypothesis evening hypothesis fails we |
37:56 | have to come up with a different |
37:57 | hypothesis so I'm looking here down at |
38:00 | all the different things once we |
38:01 | realized and that the whole zone |
38:03 | hypothesis is a failure we see that |
38:06 | there were a lot of other things that we |
38:07 | could have looked at to let us know that |
38:09 | as well one is why is this warmer in the |
38:12 | polar winters in the stratosphere when |
38:15 | there's no UV light at all it's dark and |
38:18 | why is it that in these tropical |
38:21 | tropopause the temperature is colder |
38:24 | than it is in the other ones because |
38:27 | resume li there's more UV light so we |
38:30 | can see all of these things where you |
38:33 | have problems with the ozone heating |
38:35 | hypothesis we just have to say it's |
38:38 | failed it doesn't work we now need to |
38:40 | come up with something else and we have |
38:43 | put forward this hypothesis here again |
38:45 | it's a hypothesis it's a test we've |
38:48 | subjected it to a lot of tests and it's |
38:50 | held up so far but not enough for us to |
38:52 | say this is a theory this explains |
38:55 | everything because I don't think we've |
38:57 | done enough testing of it yet but you |
38:59 | can see if we went back to the ideal gas |
39:04 | law if you looked at the equation down |
39:07 | at the bottom if I keep the temperature |
39:09 | or if I keep the pressure constant and I |
39:11 | have and I want to change the |
39:13 | temperature one way I could do was be |
39:15 | add heat into it which is what was |
39:17 | proposed and that would cause the |
39:18 | temperature to go up |
39:20 | another way we could have done that was |
39:22 | with we reduced end a number of |
39:24 | molecules then to keep the equation |
39:26 | balanced we would have had to rise the |
39:29 | temperature and so our particular thing |
39:31 | says that if some of the molecules and |
39:33 | the implications from our tests so far |
39:35 | is that it's oxygen if it combines yeah |
39:39 | if if if it combines to form multimers |
39:43 | then what happens does that reduces the |
39:47 | number of molecules and that would mean |
39:49 | that the temperature would go up as well |
39:51 | so this does explain why the temperature |
39:54 | would go up without ozone heating so |
39:58 | getting back to the ideal gas law what |
40:01 | you have is what it says is that if a |
40:05 | gas is in terms of dynamic equilibrium |
40:07 | that the work component the PV section |
40:10 | is balanced by the terminal component |
40:13 | the RT section and you can use this to |
40:20 | that second line there's P D and P and |
40:24 | we can calculate T so let's go back here |
40:27 | to this particular graph and we can see |
40:30 | then what we have is is this is during |
40:33 | the evening when the Sun has heated up |
40:35 | we have our three particular equations |
40:38 | of state and what we can see is that if |
40:41 | I reuse the these straight lines |
40:43 | I can refit the temperature profile and |
40:46 | you could see then we get again our |
40:50 | three different regions except the |
40:52 | changes from one state to the other but |
40:54 | what we can say now because we have |
40:56 | three equations of stage one for each of |
40:59 | the boundaries then each of those layers |
41:03 | is in thermodynamic equilibrium and this |
41:05 | turns out to be a very important thing |
41:08 | when we get on to looking at the carbon |
41:10 | dioxide behavior so that's just a |
41:16 | summary there I just want to compare our |
41:18 | three equations of state model for the |
41:21 | temperature profile with the manna Bay |
41:24 | and strickler connect radiative |
41:27 | convective model which is used by the |
41:29 | modelers today and I think there's no |
41:32 | comparison |
41:34 | you can if you find it hard to see the |
41:36 | black line data with the two with the |
41:38 | three different things I'll get onto |
41:41 | this again a bit later let's go down |
41:44 | okay so in terms of dynamics just to |
41:47 | explain what thermodynamics is with the |
41:50 | invention of the steam engine they were |
41:53 | trying to come up with ways of improving |
41:54 | the efficiency so you were turning heat |
41:57 | from burning fuel into mechanical energy |
42:01 | and that's why the H is the terminal bit |
42:05 | of the name and the diamond dynamism are |
42:08 | the diamond economic or movement end is |
42:10 | where it got the name thermodynamics so |
42:13 | it's a study of the relationship between |
42:15 | mechanical energy and thermal energy and |
42:19 | so are there a number of term a dynamic |
42:22 | laws but one of them well-known that |
42:24 | will be used and mainly here is that |
42:26 | energy cannot be created or destroyed |
42:29 | however it can be changed from one form |
42:31 | to another and it also can be |
42:34 | transmitted from one place to the other |
42:36 | you could for example have a hot glass |
42:38 | of water and move it to another spot and |
42:41 | still you've changed the energy from one |
42:43 | side of the room to the other and so on |
42:45 | what what the first law doesn't tell you |
42:48 | is the rate at which these processes |
42:51 | happen so you yeah how fast can you move |
42:54 | heat from one spot to another or how |
42:56 | fast does it change from mechanical to |
42:59 | terminal the first law doesn't tell you |
43:02 | that instead we have to resort to |
43:03 | measurements and what we look at is we |
43:06 | have a number of different mechanisms |
43:08 | have been proved provided for to say how |
43:11 | energy can be transmitted from one stage |
43:14 | to the other and these are the only |
43:17 | mechanisms that are used in the computer |
43:20 | models that try to profile the |
43:22 | atmosphere and what we ask is is this |
43:25 | enough |
43:26 | is there something missing and what we |
43:28 | soon discovered was yes |
43:30 | there is so up until now people have |
43:33 | been saying conduction convection |
43:35 | radiation and acoustic like I'm talking |
43:38 | to you so I'm sending energy through the |
43:42 | air but not at the air doesn't actually |
43:45 | travel to you |
43:46 | and I'm have we've arranged a simple |
43:49 | experiment here that should have been |
43:51 | done years ago |
43:52 | and we'll point out an overlooked |
43:54 | mechanism for transferring heat through |
43:57 | the atmosphere so do you want to do that |
44:00 | yeah so what we've done is we have here |
44:04 | a 100 meter a hundred 100-yard sorry |
44:12 | what we have here is a hundred yard |
44:15 | piece of tubing going from one end of |
44:17 | the hall to the other and we have here a |
44:21 | plunger that's it so if you pull that up |
44:24 | Ronen yeah if you post that up what you |
44:27 | can see is within a few seconds the a |
44:31 | liquid is being sucked up in the tube |
44:33 | and if you push it back down again the |
44:35 | liquid has been pushed back down it's |
44:37 | it's the biggest length longest single |
44:40 | use plastic tube that we have at the |
44:42 | moment so see if you just see the red |
44:47 | bit there just lift it up again you can |
44:50 | see how rapid the response is now this |
44:53 | is a very controlled exponent up a bit |
44:55 | higher Darren yeah this is a very |
44:56 | controlled experiment this experiment we |
44:59 | can calculate how all the different |
45:01 | mechanisms try to contribute to causing |
45:06 | us to do this work on the underwater in |
45:10 | the container |
45:14 | I'm applying here work energy you know |
45:18 | this is PV I'm moving it and the work |
45:23 | energy is being transmitted through this |
45:25 | big long a hundred meter tube which |
45:29 | contains air and then it's the energy is |
45:33 | ending up over here the work energy has |
45:34 | been done at the other end so so this is |
45:37 | mechanical energy so this is a mechanism |
45:40 | of transmitting energy mechanically but |
45:43 | now up until now all the models have |
45:45 | been worried about transmitting energy |
45:47 | using terminal processes so we have |
45:50 | calculated exactly what the energy |
45:52 | transmission is for each of these |
45:54 | mechanisms and you can see here that the |
45:57 | overall rate at which the energy has |
45:59 | been trans |
46:00 | mr. down along that tube it's a very |
46:01 | small narrow tube but if we were to make |
46:03 | a 1 meter square that will be two and a |
46:06 | half thousand watts of energy is the |
46:09 | rate of energy transferred out in our |
46:11 | data - whereas all the methods just used |
46:14 | by the way the computer models and the |
46:17 | theories up until now come to less than |
46:20 | 2 watts so for some bizarre reason |
46:22 | people have ignored a net energy |
46:26 | transmission mechanism that's three |
46:30 | orders of magnitude greater than any of |
46:33 | the others and we look to see if where |
46:36 | people would describe this in the |
46:38 | literature and there wasn't anything we |
46:40 | had to come up with our own name for it |
46:42 | which we call perfection another term |
46:45 | would be you know true mass energy |
46:48 | transmission mechanical energy |
46:50 | transmitted so this can go against the |
46:53 | temperature that water could be colder |
46:56 | or hotter it wouldn't affect the rate of |
46:58 | which the mechanical energy is |
46:59 | transmitted so it's independent of the |
47:02 | eternal transmission mechanism so in |
47:04 | other words we could freeze the syringe |
47:07 | of one end and heat that up to boiling |
47:09 | water and the energy would still |
47:11 | mechanical energy would transmit from |
47:13 | the colder to the Harvard direction yeah |
47:15 | so just give an explanation for how this |
47:19 | would happen here we have the famous |
47:21 | Newton's Cradle and if you apply |
47:23 | mechanical energy you can see imagine |
47:26 | that they are the atoms inside in the |
47:28 | tube you can see you apply the |
47:30 | mechanical energy of one end it comes |
47:32 | out the other end but the molecules in |
47:33 | between don't move they vibrate back and |
47:37 | forth a bit but they don't move from one |
47:39 | end of the device to the other and this |
47:41 | is what we think is happening yes I just |
47:43 | just show it in that like again what |
47:46 | we're doing here is this is obviously |
47:49 | not by air but you can see that like I'm |
47:52 | applying work energy here and the work |
47:56 | energy ends up on the other side but the |
47:58 | the balls in between they're staying |
48:01 | where they are so the the energy is |
48:03 | being transmitted from one side to the |
48:05 | other the interesting thing is that this |
48:08 | mechanism that's happening in the |
48:11 | Newton's Cradle can't be described using |
48:14 | the standard models maybe now we'll have |
48:17 | take include perfection into it it might |
48:20 | be possible what we're saying is we |
48:24 | believe that there are greenhouse gases |
48:27 | that they adsorbed energy and they emit |
48:31 | energy and one of the of Einstein's |
48:35 | famous paper that he published exactly a |
48:38 | hundred years ago today in 1919 he |
48:42 | showed that if a gas was in |
48:44 | thermodynamic equilibrium the rate of |
48:47 | adsorption by an infrared gas the rate |
48:51 | of adsorption was equal to the rate of |
48:53 | emission so in other words if you |
48:55 | increase the amount of infrared active |
48:58 | gases in the atmosphere you will |
49:00 | increase the rate of absorption but at |
49:02 | the exact same time you will increase |
49:05 | the rate of emission so if the gas is in |
49:09 | thermodynamics equilibrium you won't get |
49:11 | a greenhouse effect it won't store the |
49:14 | energy and what we have shown by our |
49:16 | data is yes the gas the air is in terms |
49:19 | of dynamic equilibrium |
49:20 | now the climate models have decided to |
49:24 | ignore Einsteins Einstein when he came |
49:28 | up with the equation he said the rate of |
49:29 | adsorption is equal to the rate of |
49:31 | emission but there were two types of |
49:33 | emission one was the standard emission |
49:35 | from a hot body a random one the other |
49:37 | one is photo induced emission and this |
49:40 | is the emission that's used for to |
49:41 | develop lasers and so on but what that |
49:44 | says is that and what will happen is |
49:49 | that the infrared active gases will aid |
49:52 | the transfer of energy from a hot area |
49:55 | to a cold area but it won't store the |
49:58 | energy so let me go back to then |
50:02 | comparing the night and day what I'm |
50:06 | looking at here is showing you that this |
50:10 | this is not a a one-off event the one |
50:14 | that I showed you in January here's |
50:16 | Tucson for the start of this month the |
50:18 | first week or so and what I want to draw |
50:20 | your attention to is that every night |
50:23 | day the temperature gets heated up and |
50:25 | every day it cools down at night |
50:27 | but the Sentra bit the central purpose |
50:30 | that doesn't go through rapid |
50:32 | temperature changes so what happens to |
50:34 | the energy that's stored in the boundary |
50:37 | layer remember you're talking of about |
50:38 | two and a half tons of there air per |
50:42 | square meter it's a lot of energy and |
50:44 | this is just representing it another way |
50:47 | the bottom axis is time so this is for |
50:50 | the entire month of May you can see a |
50:52 | ground level the temperature zooms up |
50:54 | and down and by the time you get up to |
50:57 | 700 that day/night variation is gone but |
51:01 | the lower upper ones they are but they |
51:04 | they don't have the same day/night |
51:07 | effect the other thing that I want to |
51:10 | point out here is that and that that |
51:14 | energy data what we're told is that |
51:17 | supposed to be heating up the as you can |
51:20 | see here I've plotted the humidity the |
51:22 | amount of water vapor in grams per cubic |
51:24 | meter that was in the atmosphere that |
51:27 | you also get from the same radio balloon |
51:28 | data and if what we are led to believe |
51:32 | we're true what we should see is that |
51:34 | energy at night it's going it's |
51:37 | vanishing he's going somewhere I say |
51:40 | it's going out to space but if it was |
51:41 | being trapped by infrared gases then on |
51:45 | the third slide tree inside for that's |
51:48 | interesting our side six you have a |
51:51 | water vapor there in the atmosphere at |
51:54 | the night so that should be trapping the |
51:56 | atmosphere what it actually does is it |
51:58 | cools it in other words the atmosphere |
52:00 | is behaving exactly as Einstein's law |
52:02 | predicts and not as the global warming |
52:05 | things so in other words the infrared |
52:08 | water vapor is serving to cool the |
52:10 | atmosphere at night even faster and the |
52:14 | other thing that you'll see is that the |
52:18 | that during the day the water vapor |
52:21 | there that are actually he helped the |
52:23 | atmosphere it's true because you've got |
52:25 | the sunlight coming in and that sunlight |
52:27 | that has been adsorbed and if you looked |
52:30 | at the spectrum we showed earlier that's |
52:32 | why we we see the water vapor things so |
52:37 | we'll go on to our new findings but what |
52:40 | I can say is |
52:41 | the data from the weather balloons has |
52:44 | shown quite categorically there is no |
52:47 | greenhouse effect increasing greenhouse |
52:49 | gases will increase the rate of |
52:52 | adsorption but because the atmosphere is |
52:54 | internal dynamic equilibrium it also |
52:56 | increases the rate of emission the next |
52:58 | net effect is no okay so yeah there's a |
53:08 | lot of material there and like we'd |
53:10 | encourage you to to read Stone to look |
53:12 | at true the those papers that are on |
53:15 | that opha website and we are that was |
53:20 | like five years ago that we put put |
53:22 | those but like we we haven't gone static |
53:25 | since then and so we continue to it's |
53:28 | we've also been writing a lot of papers |
53:30 | with Williams yeah yeah yes but we have |
53:32 | been carrying out this other work and |
53:34 | this work is again we would be |
53:36 | publishing with really shortly yeah yeah |
53:38 | so we're just writing up at the process |
53:41 | a a couple of papers I we don't I don't |
53:44 | know we don't have a whole lot of time |
53:45 | so we'll just kind of speed through this |
53:47 | just to give you a flavor of what's |
53:49 | coming down the tracks |
53:51 | and just okay on the laps rate um this |
53:57 | is the under on the left hand side you |
54:00 | could see the standard atmosphere and |
54:03 | the lapse rates as you go up in the |
54:05 | atmosphere according to that and you can |
54:07 | see it's a very lot of straight lines |
54:10 | what we've done on the right hand side |
54:12 | is we've looked at I think there's about |
54:14 | five million weather balloons used for |
54:17 | compiling those particular averages I |
54:20 | going back to the 50s and in some cases |
54:23 | even further and what we're finding is |
54:25 | broadly they if you were to try and fit |
54:29 | the right hand graphs in terms of |
54:31 | straight lines it's it's it's kind of |
54:33 | okay but the reality is that the lapse |
54:36 | rate isn't as straight it's not exactly |
54:40 | six and a half it's it changes and you |
54:43 | know the next point is those are |
54:44 | averages at any given a mandated level |
54:50 | if you look at the lapse rates there the |
54:52 | average is of the order of six |
54:55 | and a half and the troposphere well you |
54:57 | need to look at histograms so it's not a |
55:00 | constant and the implications of that |
55:04 | are well as weather hurry on this one |
55:06 | okay so what deviations can't remember |
55:09 | the convective adjustment that was |
55:11 | assuming that the lapse rate was exactly |
55:13 | six and a half it's not there's a lot of |
55:16 | variability and there's an intriguing |
55:18 | paradox that's implicit in the current |
55:21 | models what they're doing is they're |
55:24 | assuming that I would talk about this in |
55:26 | a second but that each of the layers of |
55:29 | the atmosphere is Termidor analytically |
55:32 | isolated from above and be lowered |
55:33 | that's how the the greenhouse effect is |
55:37 | supposed to lead to certain parts of the |
55:39 | atmosphere heating up from the IR |
55:41 | activity but simultaneously they're |
55:44 | assuming a constant fixed lapse rate so |
55:47 | what they're saying is if the |
55:49 | temperature I J 500 millibars increases |
55:53 | because of co2 half a degree that is |
55:56 | simultaneously occurring at the ground |
55:59 | so you in other words that it's there |
56:03 | turbo dynamically connected so you can't |
56:06 | you know they want to eat their cake and |
56:09 | still have it I hear you wants you to |
56:13 | talk about this one yeah yeah just |
56:15 | quickly okay so so this is taken in |
56:20 | Germany the reason we use that was that |
56:22 | Germany has a very good radio song |
56:26 | program they emit for send up for every |
56:30 | day and so we have twice as much data on |
56:33 | any one day again you can see the exact |
56:35 | same phenomena the day/night thing is is |
56:38 | but now it has four points in it by the |
56:41 | time you get up to 850 it's almost gone |
56:44 | and you can't see any trace of it then |
56:46 | but here is the interesting thing if you |
56:48 | look between the four hundred they well |
56:52 | if you look at the five hundred and two |
56:56 | 450 what are the four hundred one you |
56:58 | see their synchronization there between |
57:00 | them it's not a 24-hour synchronization |
57:04 | but it's some of the order of four three |
57:07 | or four days but the interesting |
57:09 | is that if you look at the 201 above the |
57:12 | strata at the start started stratosphere |
57:15 | that's an T synchronized it's going in |
57:17 | the opposite direction so what it is |
57:19 | happening is whatever's causing this |
57:21 | change in the compressibility of the gas |
57:26 | whether it's our multimeric hypothesis |
57:28 | or something else if the area that come |
57:31 | compressed jumps way down which is what |
57:34 | we saw from the video then that would |
57:37 | mean that we're decreasing we would be |
57:40 | making a sort of partial vacuum and that |
57:42 | we would be sucking up the air from down |
57:44 | below I'm pulling the air from the |
57:47 | stratosphere down now if you pull air |
57:49 | upwards it gets colder and if you pull |
57:52 | it down it gets warmer and that's why we |
57:55 | think that you have this anti |
57:57 | synchronized raishin above this stratify |
58:00 | the tropopause it's going in one |
58:03 | direction it's going down or up and it's |
58:06 | doing the alterations so what Michael is |
58:08 | describing by the correlations and anti |
58:10 | correlations we weave what we're doing |
58:13 | here is what we find is the temperature |
58:16 | at which that phase changed that's the |
58:19 | the point of intersection between those |
58:22 | two lines if you recall of the molar |
58:23 | density pressure plots the point of |
58:26 | intersection if we measure the |
58:27 | temperature there we find that that |
58:29 | temperature goes up and down up and down |
58:31 | if you look at the ground temperature |
58:33 | that goes up and down and what we're |
58:35 | finding is if you take for a given time |
58:38 | of the day two we can to remove the |
58:41 | day/night effect you can look and see |
58:45 | how is the temperatures at each of the |
58:47 | mandated levels correlated to the ground |
58:51 | temperature TG and the temperature of |
58:54 | the phase change TP and we're looking at |
58:59 | just for one zone for this preview here |
59:02 | which is 470 stations by 10 million |
59:06 | balloons over a 30-year period from 1989 |
59:10 | to 2018 |
59:11 | this is just for January we're just |
59:13 | showing you what we find is that the |
59:16 | temperature changes at ground are quite |
59:20 | correlated to the changes as you go from |
59:23 | the album |
59:23 | is fear that's the one on the left but |
59:26 | she can see that it rapidly falls off |
59:28 | and that up near the stratosphere it |
59:31 | actually comes slightly anti-correlated |
59:33 | but there's almost no correlation if |
59:35 | however we look at the phase change the |
59:38 | TP this is the point of intersection if |
59:41 | we look at a temperature of that dashed |
59:44 | black line in the video Michael was |
59:46 | showing you um that correlates far |
59:49 | better with the bulk of the atmosphere |
59:51 | like we're talking of seventy percent |
59:52 | its anti-correlated in the troposphere |
59:55 | uncorrelated above the troposphere and I |
60:00 | what you do or squared you can see this |
60:04 | and I just want to stress sorry I just |
60:06 | want to stress that graph on the right |
60:09 | nobody has been looking at this check |
60:12 | this intersection of molar density plots |
60:15 | before so this is a new result |
60:17 | completely near nobody is looking at it |
60:20 | it's it's and that seems to be the one |
60:23 | that seems to explain everything best |
60:25 | just what we think for the climate |
60:29 | models like my background is in computer |
60:31 | modeling that was my PhD I'm not a |
60:34 | critic of computer models as so they're |
60:37 | very useful to but they should be |
60:40 | continually compared with data and |
60:42 | observations so you know there is a |
60:45 | nobody has been looking at this they've |
60:48 | just been assuming the models are the |
60:50 | best we've got and we should be checking |
60:54 | at experiments and so um there are the |
60:58 | different improvements we believe should |
61:00 | be made I don't know if there's time for |
61:03 | questions we have another three minutes |
61:05 | before the clock actually heats so eight |
61:08 | minutes eight minutes okay oh yeah with |
61:12 | questions yeah |
61:21 | I'm a retired operational weather guy I |
61:24 | used to be the weather unit commander |
61:25 | here four years ago at davis-monthan and |
61:28 | now also a sail plane pilot so all the |
61:32 | stuff that you're saying makes perfect |
61:33 | sense like I say I come to this from an |
61:37 | operational weather point of view we |
61:42 | know that the atmosphere is transparent |
61:46 | to visible radiation yes and that's what |
61:49 | you're showing yes and where there are |
61:52 | no greenhouse gases it's travel |
61:54 | transparent to the infrared radiation as |
61:57 | well yeah oh yeah yeah but but another |
62:02 | thing I want to point out is that if you |
62:04 | look at the newspapers the newspapers |
62:07 | have a lot of information if only the |
62:10 | people critiquing this would pay |
62:13 | attention one example was about a year |
62:17 | and a half ago in Siberia it got as cold |
62:20 | as it ever gets in the northern |
62:23 | hemisphere it was in USA USA today well |
62:27 | if it's as cold as it ever has been in |
62:30 | the northern hemisphere where's the |
62:32 | trapped Heat yeah also you go up to |
62:35 | Canada you know Edmonton breaks the the |
62:40 | cold temperature by 12 Celsius 20 |
62:44 | Fahrenheit not just Edmonton but a |
62:47 | hundred kilometers around it where's the |
62:49 | trapped heat obviously it doesn't exist |
62:51 | that's all I want to say thank you |
62:52 | George your talk how we agree with you |
62:56 | on your slide summary of prevention |
63:00 | experiment yeah the term that overwhelms |
63:03 | that discussion is the acoustic |
63:06 | transmission 1.4 watts per meter squared |
63:10 | I've lost on acoustic transmission okay |
63:13 | acoustic transmission is how you |
63:15 | communicated with me in other words when |
63:18 | you moved your tongue you created |
63:20 | vibrations in the air which was |
63:22 | mechanical energy which then came and |
63:24 | vibrated my ear so that's what acoustic |
63:27 | transmission is just sound sound waves |
63:31 | and it so happens that that particular |
63:32 | experiment we've devised there is a low |
63:37 | pass filter so anything with a frequency |
63:39 | of less than one Hertz wouldn't be able |
63:42 | to pass through it and so what we're |
63:44 | saying is the acoustic energy can't get |
63:47 | through that but I'd like to just add |
63:49 | just a point which we discuss in the in |
63:52 | the papers referring to that I think |
63:54 | it's the third paper on that open your j |
63:56 | website but you can think of you have AC |
64:00 | and DC in like an electric city you have |
64:04 | this alternating current and then you |
64:06 | have a DC based signal and so we could |
64:11 | think of because acoustic energy or |
64:13 | sound is a wave format you could think |
64:16 | of it as honesty akuti a c component of |
64:21 | of mechanical energy transmission but |
64:25 | what world of describing here is the DC |
64:28 | component of mechanical energy |
64:30 | transmission so while it is obviously |
64:33 | sound has been studied very heavily so |
64:37 | everyone is very familiar of sound as |
64:39 | Atlantic in a sum of transmission we're |
64:41 | actually saying is and this is well |
64:43 | known to aircraft engineers and I just |
64:45 | think there's a few of them around here |
64:47 | what actually happens is that if an |
64:51 | airplane is traveling at less than a |
64:53 | tenth of the speed of sound then the air |
64:55 | is best treated as if it's not |
64:57 | compressible as if it's a non |
65:00 | compressible material and what that |
65:03 | means is it acts like a rigid rod so you |
65:06 | could look upon this big long tube of |
65:08 | air because it's taking its traveling at |
65:10 | about 34 meters per second less than the |
65:13 | speed of sound or less than 10% so it's |
65:16 | like as if it's a long rigid rod and you |
65:19 | just push it at one end and it sticks |
65:21 | out the other end and we after you do |
65:25 | record I will around the record yeah |
65:27 | heard of the giant Large Hadron Collider |
65:34 | well we have called this here is the |
65:37 | Large Hadron Collider because of what |
65:40 | it's doing to all those beautiful models |
65:42 | I got one one last question here simple |
65:47 | energy energy transfer and in my I'm a |
65:52 | geophysicist and one of the things that |
65:54 | occurs to me is is that we have a lot of |
65:56 | solar interaction with our with earth |
65:59 | and energy being transmitted from our |
66:02 | borealis and and-and-and the Aurora's |
66:06 | that we see and when we wonder if |
66:08 | there's at those high altitudes whether |
66:11 | and whether any of that energy impacts |
66:13 | our gases in the atmosphere well in |
66:17 | those diagrams that we showed you there |
66:19 | where the phase change was moving up and |
66:23 | down and we found that when you dampened |
66:25 | out the day-night thing you were still |
66:27 | getting these fluctuations what causes |
66:30 | that we don't know yet that's still an |
66:33 | open question there are the reason it's |
66:38 | an open question there's nobody even |
66:39 | thought to ask it until now |
