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.
