WINTER 2021/2022: Nina could affect the cold seasonThere are no more doubts, here comes Niña for next winter. There is still about a month to go before the cold season starts, however, thanks to the seasonal forecasts and some atmospheric indices we can already get a general idea of ​​what awaits us and that, attention, it could also be very different from the trend of recent years.
Indeed, the phenomenon of Girl, with direct consequences also on Italy, already from December.
So let’s take the point to understand what is it, so to clarify and hypothesize one general trend on precipitation and temperatures.

Based on the latest seasonal projections of the European Center (ECMWF) thebeginning of December it will likely be characterized by thermal values above the reference climatic averages of about 1 / 1.5 ° C, in particular on the Northern European sector between Scandinavia and Russia (the cradle of cold), more on average on the Mediterranean basin.

The cause of these anomalies is to be found far from the Old Continent and more precisely in the area ofPacific Ocean. In fact, the presence of the Girl.
This particular phenomenon basically indicates a cooling down the temperature of the surface waters of the Pacific Ocean central and eastern which frequently influences the climate of our planet, with different reflections also in Europe and in Italy. As we can see in the map below, the last reading of the surface temperature of the waters of the Pacific Ocean (September 2021) indicated it lower by about 0.5 ° C compared to the average and in the coming months the trend should be for a further decline (-1.2 ° C).

It is conceivable that the presence of La Niña could increase the entry of numerous disturbances in descent from the Atlantic which would not find any obstacle from a high pressure that could instead take refuge in North Africa. The first part of winter, if this were confirmed, would be rather rainy in the central-northern European sector, with effects also on northern regions of our country. On our mountains, therefore, the name it could be abundant, to the delight of winter sports lovers.
But be careful, in case of cold air breakthroughs it is not excluded that it can reach the plains of the North, as happened in the last winter season in the first weeks of December.

Cooling of Pacific Ocean surface watersNext winter: La Niña’s return confirmed
