Sensing Atmospheric Dynamics (by Diego Fdez-Sevilla)

Sensing atmospheric dynamics by Diego Fdez-SevillaAtmospheric dynamics involves observational and theoretical analysis of all motion systems of meteorological significance, including such diverse phenomena as thunderstorms, tornadoes, gravity waves,tropical hurricanes, extratropical cyclones, jet streams, and global-scale circulations.

It is a very common practise to look at Atmospheric Dynamics from above thanks to the satellite era. Based on the images obtained by several satellites and sensors we can try to identify the composition of the atmosphere as well as to study the dynamics resultant from the generation of currents created from thermal contrasts, atmospheric composition and the Coriolis effect.

All these resources are available at different degrees of freedom in the digital world offered in the internet by the different space and meteorological agencies. And yet, all this information comes in a format which does not relate to any of our senses. So it becomes a great experience when I can close the loop by having the chance of experiencing in first person, some of the atmospheric dynamics involved in the line of research that I discuss in this blog.

In the previous post, A Climate “Between Waters” (by Diego Fdez-Sevilla). (

Jet Stream over Iberian Peninsula DiegoFdezSevilla7e58fb84-5ad5-4319-99fb-022c4eab609f-originalOne comment that I made at LinkedIn about my point of view over the present situation is that when the fingers of the Jet Stream comes down to touch tropospheric levels in a humid saturated atmosphere, like the one in the Mediterranean sea, all countries beneath are exposed to extreme events. Gasoline needs an igniter to explode, atmospheric water vapour just needs a thermal shock (extremely cold air) to ignite energetic events.

Couple of days later, the 13th of September, I was in a rural location in Spain, in the province of Leon, characterised by a flat topography.  And just in front of me, over my head, I had the chance to sense, observe and record, how water vapour becomes condensed under the influence of colder air coming down from above.

After couple of days with a warm and settled weather, this day, I could feel the cold, I could sense the windy conditions and I could see the trails from air planes (contrails) dissipating rapidly in the sky. All those signs pointed to what I could confirm later when I had access to satellite images. The Jet Stream was coming to say hello, this time, in a tamed manner.

In the following video composition I gathered relevant satellite imagery showing the Atmospheric Dynamics observed under the influence of the Jet Stream moving down to tropospheric levels over Spain on the 13th Sept 2015. But also, I included the recording of a 30 min. video of the atmospheric developments above me speeded up in order to observe in just 1 min. (ish) what was happening. I hope that you enjoy it.

(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)gmail.com)

About Diego Fdez-Sevilla, PhD.

Citing This Site "Title", published online "Month"+"Year", retrieved on "Month""Day", "Year" from http://www.diegofdezsevilla.wordpress.com. By Diego Fdez-Sevilla, PhD. More guidance on citing this web as a source can be found at NASA webpage: http://solarsystem.nasa.gov/bibliography/citations#! 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 previous work as scientific speaker in events held in those countries as well as in Switzerland and Finland. After couple of years performing research and working in institutions linked with environmental research and management, I find myself in a period of transition searching for a new position or funding to support my research. In the present competitive scenario, instead of just moving my cv and wait for my next opportunity to arrive, I have decided to invest also my energy and time in opening my own line of research showing what I am capable of. The value of the data and the original nature of the research presented in this blog 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. I hope that this handicap do not overshadow the value of my work and the intellectual rights represented by the license of attribution attached are respected and considered by the scientist involved in this line of research. Any comment and feedback aimed to be constructive is welcome. In this blog I publish pieces of research focused on addressing relevant environmental questions. Furthermore, I try to break the barrier that academic publications very often offer isolating scientific findings from the general public. In that way I address those topics which I am familiar with, thanks to my training in environmental research, making them available throughout my posts. (see "Framework and Timeline" for a complete index). At this moment, 2017, I am living in Spain with no affiliation attachments. Free to relocate geographically worldwide. If you feel that I could be a contribution to your institution, team and projects don´t hesitate in contact me at d.fdezsevilla (at) gmail.com or consult my profile at LinkedIn, ResearchGate and Academia.edu. Also, I'd appreciate information about any opportunity that you might know and believe it could match with my aptitudes.
