【Questions】
Why did the first snow come so late this winter?
Is this snow counted as “first snow”? The first snowfall in Beijing refers to the first large-scale snowfall process in the Beijing area. According to the meteorological department, the first snow in Beijing needs to meet one of the following conditions: when more than 10 of the 20 artificial stations in the city observe snowfall; or all 5 stations in the city (Chaoyang, Haidian, Fengtai, Shijingshan, and Observatory) observe snow There is snowfall; or three or more of the five stations in the urban area observe snowfall, and at least one station has snowfall ≥ 0.1 mm.
The reporter learned from the Beijing Meteorological Bureau that the snowfall has reached the first snow standard. As of 17:00 on January 12, 16 of the 20 artificial observation stations in the city have observed snowfall. Therefore, the first snow in the winter of 2022-2023 is determined to be January 12, 2023, compared with the average of December 3 in 1991-2020. 40 days late.
In the winter of 2021-2022, the first snowfall in Beijing is fierce. The first snowfall came on November 6, and it reached the level of blizzard. Why did the first snow come so late this winter? According to reports, due to insufficient water vapor in the early stage, Beijing has always had a sunny, cold and dry weather pattern with poor water vapor conditions. Not only in Beijing, but also in Tianjin, Shijiazhuang, Taiyuan, Jinan and other places, the first snow is more than a month late.
Zhang Juan, a meteorological analyst at China Weather Network, said that the cold air affecting our country this time is strong and slow, and there is a south branch trough to cooperate with water vapor transmission, so the range of rain and snow is wide. The rest of my country except Tibet All areas will be affected by rain and snow successively. The first snow in Beijing also followed.

●Driving on snowy roads must achieve the “three slowdowns”. First, start slowly, step on the accelerator lightly, and start slowly; second, turn slowly, increase the turning radius appropriately, and turn the steering wheel slowly; Judgment, control the speed of the vehicle, and avoid sudden braking.
●After the rain and snow, the temperature in some mountainous areas in Beijing dropped below zero, and the rain and snow condensed after falling on the ground, forming the phenomenon of “earth piercing”. When driving through the “earth-piercing” road section, you should hold the steering wheel tightly and drive slowly in low gear to prevent the car body from slipping out of control.
