Climate, frost returns to Italy: the fault of stratwarming?

A new wave of frost arriving on Italy at the end of the week, with changes in the European climate: a drop in temperatures is expected.

A new wave of frost approaches towards theItaly. The weather looks set to change dramatically as the weekend approaches, forecasters say, when a block of cold air causes a drastic drop in temperature.

Tuesday and Wednesday will be marked by an overall stable weather. First drop in temperatures starting from the last hours of Thursday, which will become more marked from Friday. However, Saturday will be the coldest day, below zero North and the innermost areas of the Center.

Frosty climate also expected during the daytime, with temperatures just above zero in Northern and Central Italy. Strong winds are expected in some areas, which will increase the sensation of cold caused by low temperatures.

Climate, extreme cold due to stratwarming?

Climate changes and extreme cold waves increasingly frequent in Italy. Blame the “stratwarming“According to the researchers ofMilano-Bicocca University and of Harvard University, who published a joint study entitled “Decoupling of the Artic Oscillation and North Atlantic Oscillation in a warmer climate“.

As scholars explain, the term “stratwarming” identifies a sudden warming of the stratosphere which results in a split in the polar vortex. According to the researchers, in recent days the stratwarming has also managed to influence the tropospheric polar vortex, thus opening up to incursions of freezing air on Italy and the other countries of the Mediterranean area.

The Italian and US researchers also pointed out that at the turn of New Year 2021 there was a stratospheric warming close to the Arctic of particular intensity. Around 50 degrees Celsius, the Milano-Bicocca scholars explained. As a result, climatologists continue, an instability of weather conditions European countries, but also in North America.
