Weather: END OF DECEMBER and NEW YEAR’S EVE, IRRUPTION BY CONFIRMED FROST IN ALL ITALY. Upgrades
For the new year possible cold wave of RussiaMajor updates on major weather models are coming in for the latter part of December. In fact, the search of one is confirmed russian icy air mass with Consequences directed as a wholeItaly. So let’s find out what to expect by tracing a general trend for late 2020 through New Year.
In the coming weeks, the Russian sector and part of the Scandinavian peninsula will suffer a marked cooling with values of several degrees below zero. The map below clearly shows anegative anomaly in the temperature range, a clear sign that the infamous is forming “Russian-Siberian Anticyclone“, Or”Russian bear“as meteorology enthusiasts kindly call it. It is essentially ahigh thermal pressure, which is formed by the accumulation of cold air in the lower layers as a result of the strong and prolonged dispersion of the heat accumulated during the day during the cold season. The air that gradually accumulates in the lower layers, increasing in density and therefore in weight, tends to be compressed and this compression can cause pressure values on the ground to be reached even of the order of 1060 hPa and temperatures down to -30 ° C.
L ‘hypothesis, confirmed by the models, is that part of this powerful icy bubble may slide first towards Eastern Europe and then towards Italy, giving way to a‘frost wave pretty intense between the end of 2020 and the new year.
Obviously, given the temporal distance, we invite caution, since the configuration could undergo important changes. But the plant seems to be there.
