Why is the weather abnormal in Hunan this year?

Spring in Hunan is a changeable season.

Xie Yijun said that due to the special geographical landform and monsoon climate characteristics, the daily variation of spring temperature in Hunan ranks first among the four seasons, especially in March and April, when the weather changes dramatically and rapidly.

"Spring is in the transitional season, and the cold and warm air is active and powerful, and the two play a game with each other.

When the weather continues to be fine, the temperature will easily climb again and again; When the cold air in the north moves southward, it will lead to a sudden drop in temperature. "

In addition, under the background of global warming, it is more likely to cause climate instability, and the increase of extreme weather has become a trend.

In addition, strong convective weather in spring and summer has also entered a period of high incidence.
