What are the characteristics of heavy snow solar terms?

1, weather change: heavy snow is a solar term relative to Yu Xiaoxue, which means that the possibility of snowfall is greater than that of light snow, and the possibility of snowfall is greater than that of light snow. This doesn't mean that there must be a lot of snowfall. On the contrary, after the heavy snow, the precipitation in various places decreased further. At the same time, the temperature will drop significantly and the weather will be cold.

2. Weather characteristics: The average temperature in most parts of the north will be between -5_-20℃, while after the strong cold air in the south, frost will sometimes appear.

3. Heavy snow: After the heavy snow, large-scale snowfall or local blizzard will enter all parts of the north. Snowfall has many benefits, especially for alleviating winter drought, freezing farm diseases and insect pests and promoting winter tourism. However, the snowy road is slippery and the snow is frozen, which easily leads to civil aviation flight delays, road traffic accidents and lane congestion; In some areas, the closure of mountains and roads by snowstorms will also pose a threat to the safety of people and animals in pastoral grasslands (commonly known as white disasters).

4. Freezing rain: After heavy snow, if strong cold air forms and reaches the south, especially in Guizhou, Hunan, Hubei and other places, freezing rain is prone to occur. When freezing rain occurs, uneven ice shells appear on the ground and objects, which will have a great impact on traffic, electricity and communication, and will also cause damage to fruit trees.

5. The occurrence of rime: generally from June 165438+ 10 to February of the following year, it is more common after heavy snow. In the northwest, northeast and most areas of the Yangtze River basin, rime will appear one after another, especially in mountainous areas with high humidity. Every year in 65438+February, when the temperature in the middle and lower reaches of the Yangtze River is _ 3 ~ 0℃, freezing rain is easy to occur, and the probability of freezing rain is high.
