European weather. Old News, Same News? by Diego Fdez-Sevilla, PhD.

(updated 16th Jan 2016)

We have already seen some similarities from this winter 2015/16 with the floods and strong winds occurred in the winter 2013/14 (see here). So, how far apart will be this winter 2015/16 from last winter 2014/15?

Last year the BBC released the following video addressing the weather events unfolding on Feb 2015:

Based on the events and the atmospheric conditions found in the Winter 2014/15  I discussed their significance in the following post:

So far the chain of events happening this year are following a common pattern with what we saw last two winters. First, downpours and strong winds, next, flooding, and after, periods of cold temp and snow. And everything shares a key point. They are “concentrated” in time, location and quantity. Also, pressure systems are developing moving across latitudes more frequently than the longitudinal patterns associated with the traditional belts associated with Hadley cells in global circulation. In Nov 2014 I purposed a theory which could explain such behaviour but its validity relies on seeing the associated events evolving accordingly.

At the current time, the atmospheric conditions we face over the western Europe share some similarities with what we saw last year due to a blocking system over the Eastern Atlantic basin inducing the Polar Jet stream to bend. Accordingly a warm mass of air moves northward over the Atlantic and a polar front moves southward, into the European continent.  This is how it looks at 15th January 2016.

Winter 2015-2016 by Diego Fdez-Sevilla

Since 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. Please take a look at publications addressing those events from previous publications in this blog or look at the categories in the top menu. Also at research-gate. Feedback is always welcomed.

Bachelor in General Biology, Masters degree "Licenciado" in Environmental Sciences (2001, Spain). PhD in Atmospheric Biology and Aerosols Dispersion (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 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.

    Perception is driven by different languages. Some people use numbers and equations as the language to study patterns meanwhile others use shapes and optical observation to identify those patterns. Like the use of models in a wind tunnel for F1 or weather forecast, numbers have their limitation. Despite languages, we all are required to go beyond opinions and work to offer arguments.
    We have already seen some similarities from this winter 2019 with the floods and strong winds occurred in previous winters 2013/14/15/16/17/18(see full index diegofdezsevilla wordpress). So based on previous analyses and the patterns discussed, how far apart is it going for this winter?
