American weather forecasters have prepared preliminary predictions about the weather that will accompany us during the coming winter. Check the long-term forecast.

As predicted by weather forecasters from the US weather service AccuWeather – Tyler Roys and Alan Reppert – the La Nina phenomenon will shape the weather in Europe during the coming winter. What is La Nina? This phenomenon occurs when the temperature of the Pacific Ocean’s surface near the equator, especially off the coast of South America, is below average. This is due to the increased activity of trade winds – permanent winds – in this part of the world. They bring the cool deep waters to the ocean’s surface, and this shapes the world’s weather.

Forecast for winter 2021 – Southern Europe

AccuWeather forecasters predict that stormy weather will prevail in Southern Europe and the Mediterranean. This will be influenced by the phenomenon of La Nina. According to Roys, the discharges are to occur mainly in Spain and southern France. Last year, France, Spain, Portugal and Belgium reported 12 storms so severe that they have been named. Such violent phenomena are associated with strong and destructive gusts of wind, heavy rains and, consequently, floods.

“Some of the strongest storms this winter are likely to occur somewhere in southern France, Spain or Portugal,” Roys said. He added that storms that would initially hit Spain or southern France could create unfavorable aura for areas further south and east.

Even if there are no storms, the rest of Southern Europe will face wet winters. Much moisture is expected to drain from the Mediterranean Sea into Italy, the Balkans and much of Turkey. According to Reppert, due to this constant stream of moisture, these areas will experience storm after storm.

Winter is the wettest season in this region. And while a stormy aura can make a significant contribution to filling drought-depleted bodies of water, it can sometimes be less desirable. After record rainfall flooded areas along the Mediterranean Sea this fall, including southern France and Italy, even moderate amounts of rain can cause water spikes in rivers and severe flooding.

American weather forecasters predict that this winter the temperature in much of southern Europe will remain close to the long-term average. However, according to Roys, in some parts of Italy, Greece and the Balkans, thermometers can show values ​​above the norm.

Winter forecast for 2021 – Eastern Europe

According to AccuWeather experts, Eastern Europe will be within the reach of extremely cold air this winter.

“If a stream of cold air is ejected from the polar vortex, some of it may reach some regions of Eastern Europe,” explained Roys. The areas most exposed to temperatures a few degrees below the long-term average are central Ukraine, regions north to Latvia and Estonia, to Slovakia and Poland.

In addition, the same active storm “route” that will increase the risk of flooding in Italy and the Balkans this winter will contribute to adverse weather conditions in Eastern Europe. The collision of moisture and freezing air will lead to frequent rain and snowfall in much of Eastern Europe. “Nasty” ice storms can occur in this part of the world with seasonally cool air, Roys warned.

Winter forecast for 2021 – Western and Northern Europe

Winter in Western and Northern Europe will be quite calm – Americans forecast. Storms will not move from west to east, which means less moisture is flowing into the UK, Ireland, Germany, Denmark, Norway and Sweden. Consequently, winter in eastern France, Germany, Sweden and Norway there will be no rainfall. This is good news for residents of regions that have experienced extensive floods during the summer months.

Prolonged dry spells can leave some worried about its effects. Synoptics reassure, however, that the consequences of a drier aura will not be so serious.

Moreover, the temperature in the first half of winter is not expected to be prone to extreme fluctuations. This could be a relief for people in Northern Europe who are concerned about rising heating costs.

At the end of winter, cold air can reach Northern Europe, especially Ireland and Great Britain. It will be related to the La Nina phenomenon. According to Roys, temperatures in northwestern Europe will drop to near or below average during the second half of winter. The influx of cold air from the east may lead to a significant increase in the heat demand of the inhabitants of this part of the continent.

In addition to bringing a cold influx from the east, the La Nina phenomenon may increase the likelihood of snowfall in Great Britain and Ireland, as well as in areas from France to Poland, especially in the later winter.
