Every year the same story: with the Polar Vortex so strong we have to try to undermine its resistance and prevent the Winter from passing without a shot.
Let’s remember that today, Tuesday 1st December, the winter season begins. Weather convention wants it to start on the first day of the month and the conditions – given what will happen from tonight – are not bad. But we know, if the Polar Vortex really affects the entire atmospheric column (don’t forget that the atmosphere is divided into various levels depending on the altitudes considered) we would risk having to talk about High Pressure to go go.
If you follow our in-depth information, however, you will know that the atmosphere is influenced by various elements, by various variables that at the slightest change (or according to mutual interactions) can upset a trend set in stone. Because certainly, when dealing with a dynamic system such as the atmosphere, there is nothing and it is good that nobody forgets it.
So far we have talked about various and possible forcing, especially La Nina. Forcing because they could “force” an otherwise compromised circulatory system. But beyond La Nina, the ocean anomalies, the QBO and so on, another element punctually returns: the Euro-Asian snow cover. Especially the Siberian snow cover, which is accelerating right now as if there is no tomorrow.
Some areas of Siberia are literally scrambled by an epochal wave of frost and snow. On the net you will find lots of videos certifying the event, the last of which concerns the city of Talnach which is part of the Krasnoyarsk territory. Although they are used to frost and snow, the snowfall in recent days has been incredible. Snow cover that is accelerating throughout the Siberian area and which could have quite a few repercussions on the hemispheric circulatory system.
First of all, for example, by creating the ideal conditions for the genesis of the well-known Russian-Siberian anticyclone. It is not certain that a High Pressure of this type will help us to save the Winter, but having it is already something. We will be able to deal in detail with the possible repercussions of this situation, therefore we invite you to follow the next updates because they promise to be extremely interesting.
