Atmospheric Composition and Thermal Conductivity. (by Diego Fdez-Sevilla, PhD)

Atmospheric Composition and Thermal Conductivity. (by Diego Fdez-Sevilla, PhD)

Last 6th of July I published in my wall at Linkedin an image and comment which led to a brief but worthy exchange of comments. So I believe that it is worthy to have it as an entrance here.

The heat that is invading northern latitudes at the South of Europe not only is pushing the jet stream north, but it is finding the conditions suitable for this mass of air to become persistent in location. I believe that this can only happen due to atmospheric composition and thermal conductivity. Here it is an image showing the state of the atmosphere in the South of Europe and West side of the Mediterranean sea from the ISS.

Diego, you know, I am a layman in your field but studious, so I have a question: What do you mean by “atmospheric composition and thermal conductivity”? It sounds like something/someone is “choreographing”(to speak in dance terms) this scenario…

I do believe that there is a choreography in the atmospheric circulation and patterns we see in the weather around the globe, that is why I have developed and proposed a theory to explain present and future scenarios in atmospheric circulation Basically the interpretation I make from the data available (numerical and observation) tells me that warmer masses of air are reaching higher in altitude and latitude in the atmosphere than they used to. The transmission of heat requires molecules to transfer it “thermal conductivity”. So in order to have heat somewhere, you need the presence of molecules carrying it, “atmospheric composition”.

The capacity to contain heat is higher for CO2 and Water vapour than other components of the air, like Oxygen and nitrogen. This basic principle is also applied to explain how Thermoses (Vacuum Flasks) Work.

With the permission of weather forecasters, we could make a home-made kit for climatological studies based on understanding how it works a Thermo flask, a pressure cooker and a rocking fountain.

Thermo flasks tell us about how heat gets from one place to another, pressure cooker tell us how an increase of heat raises the amount of water vapour in relation with heat in a contained space (our atmosphere), and a rocking fountain tell us about the saturation threshold or tilting point, where all the hell breaks loose. e.g. Venice Tornado 8th July. (image bellow)

Venice Event Tornado by Diego fdez-SevillaAnother relevant matter is to understand that heat, wind and rain, are all carrying energy in different forms.

Met Office 3rd August. A low pressure system off to the west of the UK is generating some big waves which are set to affect western coasts through today and Tuesday. Waves of between 2-4 metres (about 6-12ft) are expected through the peak of the swell early on Tuesday at exposed beaches in the South West. As the low gets closer to the UK it will track to the north of Scotland, but the waves it has generated will continue marching east towards our coasts. The size of the waves on any given beach will depend on a number of local factors. Tides are not particularly large at the moment, meaning the risk of coastal flooding is low for the next few days despite the big waves.

What the greenhouse effect allows is an increase in the amount of energy being contained and spread all over the atmosphere in all its forms, latent heat, potential energy carried by the mass of water in the atmosphere and kinetic energy from thermal contrasts. Those forms of energy are not found homogeneously distributed in time and location but being defined by the dominant conditions in the region at a particular time.

To what extent the moon affects our weather?

Everything counts. The moon affects sea levels, that changes sea currents as well as compresses the atmosphere above affecting the development of pressures. Quantifying the extent of its influence, above others, on weather is a different matter. I am glad if you have fount useful my explanation. I have tried to simplify it so we all can relate to same principles applied in science. And I hope those meteorologist in my network find it suitable and not misleading. It is a challenge to integrate in a simplistic and coherent explanation all those many terms, laws and interactions involved. And yet we haven´t talked about the implications from land cover and use.

Is positive IOD index reducing the negative effects of EL NINO on rain over India? (Image by BOM)

I think that the answer lies in the question, but rephrasing the question with descriptive terms instead of acronyms.

Theoretically, an increase in the “East” Pacific equatorial sea surface temperature would move away typhoons from the west side of the Pacific and that has not happen. Even though the SST Anomalies indicate lower temp at west side of Indonesia (positive DOI) and warmer at east side (El Niño), the actual temperatures at both sides are close as well as water vapour content. I would say that keeping thermal conductivity between both sides would define the conditions for the monsoon.

When scientists declared in March 2015 that El Niño conditions had developed in the Pacific Ocean, the consensus was that the event was too weak and too late to have much effect on North America. But in the past several months, warm water has been sloshing from the western Pacific toward the Americas and El Niño has strengthened. Surface waters have grown significantly warmer in the central and eastern Pacific, and conditions have become somewhat cooler and drier in the west. By the end of July 2015, scientists at NASA and other agencies started to see some similarities between current conditions and the development of the potent El Niño event of 1997–98.

“We have not seen a signal like this in the tropical Pacific since 1997,” said Bill Patzert, a climatologist at NASA’s Jet Propulsion Laboratory. “It’s no sure bet that we will have a strong El Niño, but the signal is getting stronger. What happens in August through October should make or break this event.”

The maps provide NASA’s view of Pacific Ocean conditions. You can see snapshots of the averaged sea surface height anomalies at four different moments since March 2015. Shades of red indicate where the ocean stood above normal sea level because warmer water expands to fill more volume (thermal expansion). Shades of blue show where sea level and temperatures were lower than average (thermal contraction). Normal sea-level conditions appear in white. The maps are based on altimetry measurements made by the OSTM/Jason-2 satellite and analyzed by scientists at NASA’s Jet Propulsion Laboratory.

Last Comments

ENSO conditions and atmospheric conditions are related. BUT, instead of looking at the ENSO as a trigger for atmospheric circulation, what if we consider that the ENSO is actually a form of heat wave. From this point of view, in the actual state of the climate, we have a one single scenario in which two fluids, atmosphere and Sea waters, are absorbing, transferring and carrying heat above its average in location and simultaneously in time. I believe that this brings a completely new approach which points to an increase in thermal conductivity at global scale.

(This post is part of a more complex piece of independent research. I don´t have founding, political agenda or publishing revenues from visits. Any scientist working in disciplines related with the topics that I treat in my blog knows how to judge the contribution that my work could potentially add to the state of knowledge. Since I am in transition looking for a position in research, if you are one of those scientists, by just acknowledging any value you might see from my contribution, would not only make justice to my effort as independent researcher, but ultimately, it will help me to enhance my chances to find a position with resources to further develop my work.

I believe that the hypothesis that I have presented in previous posts in this blog (here,here and here) could help to understand present and possible future scenarios in atmospheric circulation. However, this is an assessment based on observation which needs to be validated throughout open discussion and data gathering. So please feel free to incorporate your thoughts and comments in a constructive manner.

If you feel like sharing this post I would appreciate to have a reference about the place or platform, by private or public message, in order for me to have the opportunity to join the debate and be aware of the repercussion which might generate d.fdezsevilla(at)
