Weather: the SNOW has arrived! But it’s NOT over here, with the NINA the WINTER could see LOADS of SNOW in the PLAINS
WINTER 2021/2022: La Niña could affect the cold season as in 2001 and the 80sIt is news of the last hours: the snow has already arrived! For the moment i flakes they fell on the highest peaks of ours Mountain, but it is a notable episode for the calendar, especially since we come from a period with temperatures often above the climatic averages.
Everything is confirmed by beautiful photos that come to us from the tourist resorts and the ski slopes of our Alps.
There are many reports that have come to us in the last hours: at the Stelvio Pass (2757m) the fresh mantle already exceeds i 20 cm thick. But it also snowed lower down, for example at 1800 meters above sea level Livigno (SO), with temperatures around 0 ° C and also at Santa Caterina Valfurva (SW), at 1700 meters. Similar speech also in South Tyrol, with altitudes around 1500/1700 meters, while towards Trentino It is on Veneto the snowfall level remained above 1800/2000 meters.First SNOW on the Alps (here we are at the Stelvio Pass)
That this early snow is a harbinger of a somewhat snowier winter compared to the ones we have been experiencing lately? Will there be repercussions on the next cold season?
In reality a direct link does not exist, it is in fact a isolated meteorological episode, linked to the particular synoptic configuration of this week and which has no repercussions on the next cold season.
But beware, the question is not resolved so simply.
the seasonal forecasts and some atmospheric indices they can certainly give us more information on what might happen. In particular, there is a phenomenon, that of Girl, which hangs over the hopes of name up on the plain over the next Winter. And that can affect it.
Let’s find out immediately what it is, then tracing 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 areas 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.
Finally, and that is precisely what interests us most closely, with La Niña the frequency of cold incursions, sometimes snowy, towards central Europe and Valpadana increases, while in the Mediterranean the anticyclones are more lasting with a more temperate climate and less rain.
WINTER FORECASTS EUROPE – ITALY. The reflections of the Girl on our continent they are not yet clear indeed, many uncertainties remain.
If the years characterized by the Niña are distinguished by the frequent cold raids since the end of November with prime snowfall in Valpadana a Torino, Milano, Bologna it’s at December, also in Florence, with possible episodes of Burian by February, the latest seasonal forecasts of the prestigious European center (ECMWF) are in contrast and foresee temperatures above the average of about 1 ° C. This type of overheating, expected for the next winter season, is actually in line with an 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 it, inducing a change increasingly difficult to reverse. Unfortunately.
