LONG TERM Weather: STRATWARMING in Act, ATMOSPHERE in TILT with COLD and SNOW for NEW YEAR’S EVE and BEFANA
Stratwarming over the North Pole. Cold to bitter end also for the next few weeksWinter is back, the real one, like in the old days. This year the season is ending very dynamic, cold and full of surprises. And the future prospects also look very interesting: long-term forecasts, in fact, they confirm for the next few weeks cold and icy “until the bitter end” with the possibility of Name both close to New Year, both for him Befana.
Also, something anomalous and unexpected is happening over the North Pole, which could literally cause the atmosphere to plummet, called in technical terms. Stratwarming.
Let’s find out right away what it is by charting a trend for the next few weeks with the expected weather in Italy.
Let’s start by saying that the latest updates available to us argue in favor of a cold wave series already from the last days of 2020. The worsening of Sunday 27 is confirmed, with strong snow down to the northern plains: snow is also expected in cities like Torino, Milan, Bergamo, Verona and Padua, with more than 15 cm of accumulation at the end of the event, especially in Lombardy. An unstable new impulse could then break into Italy precisely because of for the beginning of the new year, with the risk of new snowfalls in the Center-North, even at very low altitudes. Temperatures will also remain below the reference climatic averages in much of the country, quite a particular fact since it has not happened in several years.
Our attention then shifts to North Pole where, just between the end of 2020 and the beginning of the new year, a sudden stratagem. With this term, in meteorology, we refer to an anomaly and intense heating of the stratosphere terrestrial, over the Arctic region, in the order of 50 ° C in a few days. This anomalous heating of the stratosphere, once active, gradually tends to expand into the upper troposphere, with impact about him Polar vortex: It is not excluded, in fact, that you may derive your own from this division in various parts. When this happens, it can happen that the edges of the vortex itself drop in latitude, unleashing powerful frost waves all the way to the Mediterranean basin – how to forget, for example, the frigid winters of 1929, 1963, 1985, 2012 (just to name a few).
At the moment, it is still too early to know whether or not there will be a breakout in the Polar Vortex. However, according to the latest updates, the consequences for Italy in January 2021, already from Befana, With the’arrival of icy air masses, of arctic-continental extraction, which from the Siberian steppes could reach Italy, through the icy blowing of winds from the northeast quadrants: Bora, Tramontana and Grecale. In short, we may need to re-deal with the infamous Burian.
But we will talk about it again.
