Atmospheric Dynamics, GHG’s, Thermal Conductivity and Polar Jet Stream (by Diego Fdez-Sevilla, PhD.)

Atmospheric Dynamics, GHG’s, Thermal Conductivity and Polar Jet Stream (by Diego Fdez-Sevilla, PhD.)

I believe that the most visual representation of having the atmosphere increasing its thermal conductivity would be seen throughout the wobbling state of the Polar Jet Stream. As part of my research since 2013 I have been following-up the state of the Polar Jet Stream. This is the latest animation that I have made over the period February 2016 at the Western Europe-East Atlantic.

For 13 years I have been looking into the synergies driving atmospheric dynamics and the particles contained within.

In my research it has become relevant the heterogeneous distribution, composition and behaviour of:

  • monoatomic and polyatomic molecules in the atmosphere;
  • variations in pressure;
  • location of events driven by the strength of winds and thermal contrasts;
  • the enhanced atmospheric mixing ratio due to convective forcing and/or rain events
  • increasing turbulence;
  • the release transport and deposition of aerosols and their behaviour as rain drop nuclei due to their properties over clouds and rain drop formation, energy flows interacting from processes of evaporation and condensation as well as
  • biological evapotranspiration and respiration, and
  • biochemical processes affecting atmospheric composition (photosynthesis).

Furthermore in my research it has become relevant the concentration and time of permanency for different molecular compounds and their different properties interacting in energy flows such as condensable (water) and not condensable gases (GHGs).

All those factors (at least) are relevant since they either define or indicate the state of heat transfer efficiency in the atmosphere.

Derived from addressing synergies and feedbacks between those factors discussed in previous posts, some of my conclusions are:

  • GHGs have the potential of enhancing the thermal conductivity of the atmosphere increasing the capacity of the system to absorb, contain, transport and release energy (in all its forms, kinetic (wind related), thermal (Heat) and potential (mass)) throughout latitudes, longitudes and altitudes.
  • The most important component in the atmosphere carrying such intake of energy is water vapour due to the enhanced thermal conductivity of the atmosphere resultant from GHGs forcing.
  • In a first stage, due to the compartmentalization of atmospheric circulation in the poles thanks to Polar Jet streams, the Equator and Midlatitudes absorb the major change in thermal conductivity (increase in temperature).
  • Due to asymmetric distribution of land surface and GHGs conc between hemispheres, the NH receives the biggest impact than the SH.
  • Once the thermal contrast in the NH Polar Jet Stream is worn out, the polar circulation opens its volume in the atmosphere to accommodate new forms of energy carried by water vapour and GHGs, increasing its thermal conductivity.
  • As a result, the thermal transfer efficiency from mid latitudes would expand into polar latitudes, enhancing heat transfer processes northwards (heat waves) as well as the meltdown of ice caps and precipitation in liquid form out of season (already happened this winter 2015/16).
  • Also, the frequency of masses of air from Polar and Mid Latitudes crossing over the Polar Jet Stream increases the level of exposure to extreme variations jeopardising the development of natural cycles in flora and fauna, when they occur out of season, due to a weak Polar Jet Stream. (see related posts)
  • In other hand, masses of air and pressure systems containing more energy than its surroundings (Thermal/Kinetic/Potential), can create “blocking patterns”, or move higher in altitude instead of dissipating its energy when moving upwards in the atmosphere. Masses of air having the capacity of carrying such thermal energy without dissipating it when moving upwards generate what it is called Sudden Stratospheric Warming events. (also seen through this winter 2016).

My approach towards understanding atmospheric and environmental developments is based on considering that temperature is not only a measure of Energy, it is a measurement of the state for the density of a particular type of matter.

Without matter there is no temperature. So, wherever we measure temperature there is matter.

Which type of matter exists at each point where we measure temperature is the main relevant point in environmental assessments.

And then, which conditions allow for such matter to be there, in such concentration and physical state, latitude and altitude.

If temperature at Earth’s surface is increasingly spread over higher latitudes and altitudes, as they are, it is because there is molecular matter holding it.

Seeing water vapour transferring heat reaching higher latitudes and altitudes it points to an enhanced thermal conductivity in the atmosphere only explained by higher conc of GHG,s getting mixed within the atmosphere chemistry.

GHG’s have the capacity to absorb, retain and transfer heat radiated from above, below and within the atmosphere creating a positive feedback between water vapour and temperature through the whole atmospheric column and in latitude.

The most visual representation of having the atmosphere increasing its thermal conductivity would be seen throughout the wobbling state of the Polar Jet Stream.

I have addressed the state of the Polar Jet Stream since 2013. The following images show in an animation the state for the Polar Jet Stream at the NH throughout February 2016.

(Every reasoning pointed out here is linked to observed events and records which have been discussed in previous publications. For all those reasons, I appreciate any feedback in order to consolidate the validity of what my research points out from a multidisciplinary approach, or to discuss possible weaknesses suggesting the need for reassessing any consideration.

PerspectiveSince October 2013 I have been studying the behaviour of the Polar Jet Stream and the weather events associated as well as the implications derived into atmospheric dynamics and environmental synergies.

Many of the atmospheric configurations and weather and climate events we see these days are very similar with the progression followed since 2013.

Bachelor in General Biology, Masters degree "Licenciado" in Environmental Sciences (2001, Spain). PhD in Aerobiology (2007, UK). Lived, acquired training and worked in Spain, UK, Germany and Poland. I have shared the outcome from my work previous to 2013 as scientific speaker in events held in those countries as well as in Switzerland and Finland. After 12 years performing research and working in institutions linked with environmental research and management, in 2013 I found myself in a period of transition searching for a new position or funding to support my own line of research. In the current competitive scenario, in order to demonstrate my capacities instead of just moving my cv waiting for my next opportunity to arrive, I decided to invest my energy and time in opening my own line of research sharing it in this blog. In March 2017 the budget reserved for this project has ended and its weekly basis time frame discontinued until new forms of economic and/or institutional support are incorporated into the project. The value of the data and the original nature of the research presented in this platform and at LinkedIn has proved to be worthy of consideration by the scientific community as well as for publication in scientific journals. However, without a position as member of an institution, it becomes very challenging to be published.
