something is moving inside upper layers of the atmosphere it opens up hope “real winter” come to the end According to different medium-term weather forecast reports, the change is now arctic polar region. And when would it come? Everything indicates that it will be from the end of January. polar vortex. By this name, we describe the current of cold-keeping winds around the North Pole.
What happens if that vortex breaks? The cold then emerges from its ‘containment’ and can flee south. And its arrival in Spain is not ruled out.
Current models show A sudden stratospheric warming potential (CSE) that develops around and after January 20. The consequences of this CSE will be the displacement of the stratospheric polar vortex.
Juan Jesús González Alemán, PhD in Physics and meteorologist from the USA State Meteorological Institution (Aemet)He said social networks are “starting to have strong evidence for sudden stratospheric warming” and that the European IFS model “shows potential” for “major disruption in the polar vortex” by the end of the month.
Now strong evidence of abrupt stratospheric warming is starting to emerge:

unknowns
From there, there is still a lot of uncertainty. If noticed, it will belong to February. However, some conditions must be met for the phenomenon to move into the lower atmosphere. Experts hope that the situation will become clearer before the end of January. If we eventually find ourselves in front of a strong stratospheric warming moving into the lower atmosphere, cold and blizzards in the northern hemisphere, including the Iberian Peninsula. Everything will depend on which direction the arctic cold falls and how that combines with anticyclones and storms.
