# The current snowfall in Northeast China is extreme #

A few days ago, a news that "the current snowfall in Northeast China is extreme" attracted the attention of netizens from all walks of life. It is reported that due to extreme weather, the Central Meteorological Observatory continued to issue an orange warning of blizzard today, and some areas in Inner Mongolia, Liaoning, Jilin, Heilongjiang and other places have heavy or extraordinarily heavy snowstorms. South China and other places will experience cliff-like cooling. Why is the thickness of snow in Northeast Inner Mongolia so deep in this cold wave?

Specifically, at the height of 500hPa, the northeast cold vortex develops strongly, and the low trough moves eastward and northward, which leads to the explosive development of surface cyclones and forms a deep low-pressure system from low to high, which has strong dynamic uplift conditions; At the same time, the southwest airflow transported enough warm and humid air to the northeast, and the water vapor was extremely strong. It is caused by the rapid development of several weather systems and the fierce intersection of cold and warm air.

Meteorologists predict that by the night of the 8th, the newly added snow thickness in Inner Mongolia and Northeast China will reach 10 cm to 20 cm, and the local area will reach more than 40 cm. The heavy snowfall caused by this cold wave process is mainly concentrated in Shandong, Hebei, Inner Mongolia and Northeast China. Among them, some areas in southeastern Inner Mongolia, central Liaoning, western Jilin and other places have heavy snowstorms or extraordinarily heavy blizzards.

According to Zhang Guilian, an expert, the snowfall was wide, and moderate to heavy snow generally appeared in the eastern, central and southeastern parts of Inner Mongolia, especially in the south-central and southeastern parts, especially in the southeast of Chifeng City and the south of Tongliao City. The maximum snowfall occurred in Kulun Banner, Tongliao City, reaching 60 mm, and the local snow depth reached 50 cm.

During this cold wave, there was a lot of snowfall. The thickness of snow in the south of Tongliao City, the south of Chifeng City and the south-central part of southwest Xilin Gol League is more than 65438 0.5 cm, and protected agriculture will be affected by cold damage.
