This is how it looks a 3d representation of the atmospheric pressure at the North Hemisphere for today 30th January 2015.

The weather  forecast for this week over Europe is going to be challenging, with plenty of precipitations in the form of rain and snow, and strong wind power. Could this situation be part of the ongoing unsettled conditions coming from the North Pacific being dragged al over the NH by the Jet Stream? In that case, would that be between the margins of accepted “variability” or “normality”?

Here is the image showing the weather alerts being activated for Europe the 30th Jan 2015.

26 01 2015  Met Office News Blog: Cold Weather for UK

Cold weather is again on the way for the UK.  Later this week colder conditions will spread south, bringing a mixture of sunny spells and snow showers from Wednesday onwards.  Temperatures for many will be below normal for the time of year and the wind chill, due to strong winds, will make it feel very cold.

Snow showers are expected to affect parts of the northern half of the UK on Wednesday and Thursday and the Met Office has issued a yellow severe weather warning  for the potential impacts and this will be updated as required this week.  Don’t be surprised to see some snow showers across southern areas too, but these are not currently expected to be heavy enough for the snow to settle.  The northerly winds and cold weather are likely to continue into the weekend.

Is it due to the polar vortex?

There have been reports the cold weather is due to a “displaced polar vortex”.  The large-scale low pressure area in the stratosphere, known as the Polar Vortex, is displaced towards Russia and looks likely to stay that way over the next few days.  However this is not directly responsible for changes in the weather during the coming days. The cold northerly winds we are expecting at the end of the week are not unusual for winter.

What is the jet stream doing?

The jet stream is forecast to move south of the UK from Wednesday onwards. This means we will be on the ‘cold side’ of the jet and cold air from the poles/Arctic will work its way southwards to affect the UK.

Is the snowstorm in the USA coming our way?

The snowstorm affecting the east coast of the USA is not coming towards the UK.  It is expected to move away from the States, crossing the Atlantic to the south of the UK to bring heavy rain to Spain and Portugal at the end of the week.

Following the Met Office weather forecast, “the snowstorm affecting the east coast of the USA is not coming towards the UK. It is expected to move away from the States, crossing the Atlantic to the south of the UK to bring heavy rain to Spain and Portugal at the end of the week.” I remember when the North of Spain and the UK use to share the effects of the same Low pressures in Winter. Now it seems that we are getting separated by the Jet Stream … …

(This post is part of a more complex piece of independent research. 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.

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 tu further my work.

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)

For anybody interested in the posts related with this discussion here I leave you those more relevant in chronological order (there are comments bellow some of them. Please check them out):

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.
