For the last 4 years I have been publishing a line of research addressing environmental topics which has led me to consider integrating all aspects of the global ecosystem in a singular assessment which reflects a synergistic interaction between all of the phases of our environment, liquid (water cycles), solid (land use and cover) and gaseous (Atmosphere and gaseous emissions).

In 2014 I presented a theory about the common thread shared by all those components showcasing the relevance that they play within  variations in the energy flows linking all phases of the ecosystem. Such alteration would have the potential to trigger climatic drifts. Following this assessment I have kept performing assessments looking into the veracity that real time developments would add to my point of view.

There are several publications in this blog which contain the words “follow-up” which can be found easily at the Timeline page.

In particular for the present publication, in April 2016 I published a piece wrapping up conclusions gathered from the assessments carried out to such day.

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

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.

The present conditions and real-time events found in the dynamics of the atmosphere seem to verify those conclusions. Therefore, in the present publication, I offer an assessment over the those features in our atmosphere which I consider relevant in order to allow for the readers to make its own judgement contrasting my previous conclusions with the current atmospheric conditions in order to validate my assessments.

February 2017.

Through the winter 2017 we have seen already a warm event at the stratospheric Polar Vortex,


Variations in temperature over the North Hemisphere divided longitudinally instead of latitudinally,



Intrusions of warm mid-latitudinal masses of air getting into the Arctic


And the Polar Jet Stream bending to an extent that it has connected the warm mid latitudinal masses of air with Arctic circulation.


2nd February 2017. Wind conditions at 250 hPa, Jet Stream level.


9 February 2017. Wind conditions at 250 hPa, Jet Stream level.

And all of this while at the South Hemisphere, in Australia are suffering a sequence of heat waves disrupting power infrastructures.

Past and Present

Based on the actual conditions I want to share previous assessments from my research in order to compare them with actual developments with the aim to verify its value.

Closing remarks

Since the publication of my theory in Oct 2014, at my blog and several groups here in LinkedIn (like the AGU, NASA and NOA groups), the immense response offered has been silence. In Feb 2015 I published a revision and since then a constant follow-up throughout more than 150 assessments. Still today, the majority of the response is silence. So I thank your open share. I might not use the right vocabulary, or the right data or the right reasoning. But when nobody is able to offer a consensus over what is going on, I wonder, what is right this days?.

Some thoughts

Have you ever considered “atmospheric icebergs” drifting into the “open ocean” of mid-latitudes …?

Considering that I apply the concept of a “open ocean of mid latitudes” as an analogy to describe an atmospheric fluid which has not physical (continental) barriers, actually, we have seen such drift of cold chunks of Arctic air drifting over the European continent and the North American one in the recent past.

“Cold air cannot ascend”

The energy pool contained (kinetic energy) within cold air is so low that cold masses of air move passively. They move when they are pushed, heated up or sucked due to pressure variations from creating a vacuum effect. So, Warm masses of air “move” actively, they contain energy enabling them to expand doing work. Cold masses of air do not have energy available to do work, those do not “move” through doing work, they “drift” passively due to the work carried out by the energy contained by warmer masses of air.

One think might seem clear, the orbital tilt is not enough to justify the warm temperatures measured at the Arctic following gradients of temperature dictated by the Stefan-Boltzman theory, which indicates that we are moving from Orbital seasonality into Kinetic Seasonality. A change triggered from changing the order of the factors.

Also, solar drivers would have an impact following a gradient either in latitude and in altitude. Neither of both gradients are seen in the whole planet. Furthermore, the influence of Solar activity could not be restricted to drive changes differently between seasons or hemispheres, since the influence of the Sun is at global scale (northern and southern polar jet streams, polar vortexes, etc,…) and constantly through the whole motion of the Earth around the Sun independently of the tilt of the Earth. The Earth might tilt but it always has 50% of its surface and volume divided between exposure and shadow. So what happens in one 50% of the Earth has a counterpart through an equal 50% of volume, surface and time.

How much influence has the transformation being forced into all parts of the environment over pre-established energy flows, beyond the NH?

The Sun has been and it is involved in all forms of existence. Nothing new there. But knowing that the Sun interacts with us “through” our environment, like through a prism, how long before we identify the consequences from transforming such prism?

One last think,

If Energy cannot be created or destroyed, can it be produced or consumed?

Author’s Disclosure Declaration

For those unaware of the content offered in this blog I might have to issue a warning: Handle with care. Also with the product obtained from scientific analytical thinking there are traces of personal and professional “passion”, by-products obtained from “original and unpeered grey matter juice” originated from “independent critical thinking”. Also sometimes the packaging might be rough around the edges due to its “unfunded nature”.

4 years ago I joined a discussion which made me realise how much knowledge was settled on the past, built upon past conventions and unable to give answers about present developments in all parts of our environment. From the impact from GMOs, plastics, soils degradation, atmospheric composition, land use and cover, water cycles, … I had addressed scientifically unanswered questions before doing my PhD so I decided to give it a go and to offer my take over those gaps. It has been a pilgrimage to become aware of how much faith and fear is put on scientific publishing above raw understanding and discussion.

I do not know how far this blog will go, however, it represents the assessment of a global process and I expect that past posts will become a description of continuous present for the next years.

Altogether, the body of work which represents the line of research presented in this blog is composed by more than 190 pieces, covering data analyses and conceptual discussions. All those different discussions and assessments presented here build together a single concept. The format applied is the result of making a big effort trying to apply simplistic approaches with the aim to allow a multidisciplinary access. Since the topics treated in my publications have implications for many sectors in the academic and not academic world, with the aim of allowing my research for open review, there is also the objective of allowing access to a multisectorial and multidisciplinary audience sharing interest.

My agenda is simple, I am in transition looking for either funding to grow the research published in this blog or for a job position in any field in which my assets are valued. Behind my research there is nothing more, nothing else than to showcase my capabilities doing what I like, research. I am a methodologist. I don´t look at the color of the result obtained, only at the suitability of the method and the coherence of the result. As I have said before, if I am wrong on my assessments and conclusions, it will be better for all, and my work would showcase my capabilities anyway. A CV shines the goals obtained by anyone, but by publishing here my research, I expose myself and my work to public judgement. There is a difference between being naive and raw. If you see the difference you will understand better my work and my personal position.

The aim of publishing my work openly is to allow for it to be exposed for an open review. So any constructive feedback is welcome. After a period of time of at least a month from the publishing date on this blog and at LinkedIn, if no comments are found refuting the value of the piece published I then publish it at ResearchGate generating a DOI for posterior references.

In order to protect my intellectual rights, more assessment in depth and the statistical and numerical analyses that I have performed to support my arguments can be discussed at my email: d.fdezsevilla(at)gmail.com

If you find that my work is worthy to be acknowledged, share your thoughts openly and publicly because by sharing public acknowledging over the value of my work is what will help me in order to find the attention from those able to allow me access to a job position or resources to increase the functionality of my research.


(This post is part of a more complex piece of independent research. I don´t have funding, 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, hereand 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)gmail.com

Since October 2013 I have been publishing pieces of research 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. Please take a look at posts addressing those events from previous publications in this blog or look at the categories in the top menu. Also at research-gate.

    The thing with temperature averages as the main variable applied to define climatic developments and atmospheric dynamics is that between the warm Australia and the cold USA and Europe we get a pretty nice middle figure which has no meaning. And yet, the thermal gradient in both cases is steep with respect to each other, showing to be part of a global pattern of increasing convective motion in the horizontal and vertical profiles between poles. That’s what I interpret from the current developments 2019 discussed since 2013, where we can see extreme heat in Australia with a weak North Polar vortex. But I wonder how far is my view from that considered worth of attention. See full research at diegofdezsevilla.wordpress.com
