The wind in the north is so strong, in addition to the strong cold wave itself, it is also related to the formation of the “snow typhoon”. Since last night, the Mongolian cyclone has begun to develop and has arrived in Inner Mongolia today; and this afternoon, under the attack of the strong warm and humid air current, the Yellow Sea cyclone has also formed. The two cyclones will merge in Jilin and Heilongjiang to form a powerful northeast cyclone.

This northeast cyclone can be said to be a “snow typhoon.” After absorbing the power of the two cyclones, its central pressure will drop below 985 hPa, comparable to a strong tropical storm; and its wind field will cover the entire northeast, and the wind will not be inferior to today’s North China. More importantly, under its suction, a large amount of warm and humid air will converge with cold air in the northeast, and snowstorms will appear again.

The situation of this blizzard is very stable; the scope is very large, the entire northeast has to fall, Shenyang is small to medium snow, Changchun, heavy snow, Harbin, heavy to blizzard; the intensity is very strong, there will be two in the area of ​​Hegang-Jiamusi-Shuangyashan in the center of the blizzard. The day’s heavy snow-extremely heavy snow, the total snowfall will also be close to the last time Tongliao, it may be close to or break the local November record.

This is the second “snow typhoon” encountered in the Northeast this year, and also the third nationwide cold wave that my country has encountered since October. According to annual data, the average number of cold waves in my country from September to November is 1.9, and it is more in the early years, and less than 1.5 since the new century. Undoubtedly, before the arrival of winter in the climatic sense, the cold wave in our country has greatly exceeded the standard.
