As for the North Pole, a dangerous weather situation is currently brewing. An extremely cold winter threatens. Some forecasters warn.
Munich – The scenario sounds terrifying. The west wind brings winter mild Atlantic air to Germany, stops. Instead, a cold flow from the east, the Russian winter, was transported by air to the Federal Republic of Germany. The result: record low temperatures and the winter of the century. The scenario sounds dramatic, according to reports in the Washington Post, but by no means unrealistic. The meteorological phenomenon it could lead to is the splitting of the polar vortex.

winter of the century: Why the polar vortex is divided by how much cold it can bring
A split of the polar vortex can occur if the winter weather in the northern polar region has the usual dynamics. By the way, the polar vortex that transports mild air from the west to central Europe is formed there due to the lack of sunlight. At irregular intervals, however, the so-called “strong warming” occurs, the temperature of the stratosphere in several days at more than 50 degrees. To make it warmer than the air further south, it turns around the winch. Instead of the West, the air suddenly comes out of the East, the polar vortex breaks.
New York Metro Weather posted this animation of the phenomenon:

“About five to six times a decade, however, a so-called ‘sudden stratospheric warming’ occurs, stalling can lead to polar lows weakening and moving southward, or, as now before, even forming high above the North Pole. In other words : Strong westerly winds will be replaced by weaker or even easterly winds,” said climate researcher Dr. Martin Stendel of the Danish Meteorological Institute for Image.

winter of the century: What happens when the polar vortex breaks down?
Without the “polar vortex”, Europe lacks an important defense against cold weather from the east. Temperatures are significantly lower in winter, because there is no warming effect of seas and oceans. Land masses cool down much more in winter. In addition, the Gulf Stream continuously provides heat to Western Europe, which the winds redirect from the west towards Germany. The wind is turning the Russian cold is coming instead of the Portuguese mild to Europe and the winter could be really cold.
Not yet. Strong warming of the northern polar stratosphere occurs on average every two years. How strongly it affects the winds and winter in Germany depends on many factors, and it is currently impossible to predict. “According to calculations by the US Weather Service, NOAA, January will be mild. Still mild, hardly – and those calculations are from December 17th, they are so out of date. The polar vortex sounds awfully dramatic. now coming out of a century of winter. From my point of view point of view, completely too hasty,” said meteorologist Dominik Jung from the Wetter.net portal about the image.
climatologist Professor Mojib Latif of the GEOMAR Helmholtz Center for Ocean Research adds to the picture: “You can’t tell next winter before, although there are always relevant messages. That would be crystal ball gazing from my point of view. The Polar Vortex may be for the current cold weather in the United States States, but a lot of chaos has been caused and no one knows how it will develop in the coming weeks and months.”
Winter of the century: How dangerous is the splitting of the polar vortex?
A polar vortex split can bring a lot of cold. There is little chance that the biennial weather phenomenon will lead to the winter of the century. However, the separation of the polar vortex is coming this year, especially early, some weather experts. This particularly long cold air could come to Europe in winter against the cold of February. Time will tell if it is really so.
The latest GFS predicts the separation of the #polar vortex early next year. Besides my fascination with PV divisions, this could have important weather implications, including a #cooler Europe and heavier #snowfall for the NE US, but for now it remains speculative! pic.twitter.com/WUvBiVZqRh
