Weather: Winter 2022/23 la Nina arrives. It could be the year of the Snow in the plains. Latest updates
WINTER 2021/2022: Nina could affect the cold season, but there are doubtsThere are really a few months left to the beginning of the autumn-winter season but, thanks to seasonal forecasts and some atmospheric indices, we can already get a general idea of the expected time. In particular, there is a phenomenon, the Niñawhich hangs over the hopes of snow down to the plains over the next WINTER.
Let’s find out immediately what it is and then trace the possible ones consequences on Italy.
LA NINA. Let’s start by saying that this phenomenon indicates a temperature cooling surface waters of the central and eastern Pacific Ocean that frequently influences the climate of our Planet, with different reflections also in Europe and in Italy. And this is precisely what has been happening in recent months, with values of about 1 ° C below the reference climatic average. This small variation leads to one modification of atmospheric circulation on a planetary level: some regions such as Australia, Indonesia and the Philippines see an increase in rainfall, as well as the southernmost regions of Africa or the north of Brazil. In addition, the monsoons in Southeast Asia and India are strengthening. On the contrary, the area between Brazil and Argentina and the part of the United States (drought and fires in California) that overlooks the Gulf of Mexico see less rain. In addition, with La Niña, cold and sometimes snowy incursions towards central Europe and Valpadana are more frequent, while in the Mediterranean the anticyclones are more lasting with a more temperate climate and less rain.
WINTER FORECASTS EUROPE – ITALY. The consequences of this climate change taking place on the Pacific on our continent are not yet clear and indeed many uncertainties remain. If the years characterized by the Niña are distinguished by frequent cold incursions since the end of November with first snowfalls in Valpadana in Turin, Milan, Bologna and December as well in Florence, with possible episodes of Burian by February, however, the latest seasonal forecasts of the prestigious Central European (ECMWF) are bucking the trend with temperatures that could remain above the average of about 1 ° C. This type of overheating expected for the next winter season is actually in line with the increasingly evident climatic trend starting from the 90s, and fits perfectly within the broader picture of climate change and in particular of the Global Warming or Global Warming what to say if you want. If so, it would mean that Global Warming is largely offsetting the effects of La Niña, in fact annihilating itinducing a change increasingly difficult to reverse. Unfortunately.
