Why is the snowy weather extremely cold in Europe, but this kind of weather does not appear in China, the most polluted country in the world?

Nalis, a spokesman for the World Meteorological Organization, told the media in Geneva on the 4th that the cold weather sweeping Europe at present was caused by Siberian high-pressure air mass.

Nalis said that the Siberian high-pressure air mass prevented warm air from moving westward, which led to a sudden drop in temperature in Europe. In the past few days, cold air from the north and warm and humid air from the Mediterranean crossed over Southeast Europe, bringing a lot of snowfall to the region.

Nalis pointed out that the current severe cold weather does not mean that this winter is the coldest winter in Europe. "If we recall the winter from 29 to 21, we will find that the cold wave came earlier and lasted longer. It started in December 29 and ran through most of January and February 21."

Nalis said that the overall temperature in Europe was higher than in previous years throughout December last year and most of January this year, "so we don't think this cold wave can set a record for low temperature. Of course, record low temperatures may occur in some areas, and the specific situation remains to be confirmed after data collection. "

Some experts from the World Meteorological Organization believe that the severe cold weather in Europe and other regions will last for several days, but how long it will last depends on when the blocking effect brought by high-pressure air mass will end.
