What areas will be affected by the snowstorm in Hunan 16 counties?

Specifically, it will affect Huaihua City, Xinhuang, Zhijiang and Hongjiang.

Why does the cold air in Hunan form? According to the detection of Hunan Climate Center,1From October 23rd to February 7th, the average temperature in Hunan Province was only 3.6℃, 2.5℃ lower than the same period last year. There are two main factors that cause cold air in Hunan. One is the stable blocking pattern in the middle and high latitudes of Europe and Asia, which is conducive to the slow penetration of cold air and the deepening of the south. The second factor is that the trough of low pressure on the Qinghai-Tibet Plateau is extremely active, so the water vapor from the Bay of Bengal is continuously transported to China. In this process, strong warm and humid airflow and cold air are established, and the form of continuous and stable precipitation in the whole southern region of China is established.

What caused the snow in the south this year? In fact, it snows in the south this year because we are in La Nina state this year, that is, the SST in the equatorial eastern Pacific is below 0.5 degrees lower than in previous years. This phenomenon has a great influence on the climate in China. Under this influence, the meridional circulation in East Asia is abnormal, and this abnormal circulation situation is very beneficial for the cold air in the north of China to go south. Therefore, the combination of cold and warm will be affected by two air currents, so there are more rainy and snowy weather in the Yangtze River basin, and the low temperature weather will last for a long time.

What should I pay attention to in blizzard days? In snowstorm weather, the roof of the house will freeze, and it is particularly cold outside. Once people go out, they will be completely frozen. So try not to go out during the snowstorm, pay attention to the weather forecast, buy daily necessities a few days before it snows, and then stay at home and enjoy the outdoor snow scene. When driving in rain and snow, the visibility outside is low, so when driving a vehicle, control the speed, don't get too close to the vehicle in front, and keep a proper safe distance. In addition, we should pay special attention not to brake suddenly, because in snowstorm weather, the road surface is easy to freeze, and if we brake suddenly, it is easy to cause traffic accidents.
