The temperature difference is particularly large. For example, before Grain Rain this year, the temperature in some areas was as high as 30 degrees, which was very abnormal in spring.

The Siberian cold air flow in the North Pacific often goes south and often collides with the warm and humid air flow from the Indian Ocean, and frontal rain often forms on the contact front.

After Grain Rain, the Siberian high retreated to the north of the Arctic Circle. The warm and humid air flow in the Indian Ocean and the rise of subtropical high occupy most parts of China. Under the dual control of the subtropical high and the warm and humid air flow in the Indian Ocean, there will be plum rains, rising temperatures and frequent weather conditions such as thunder and lightning and strong winds in China. Therefore, it is best to catch Grain Rain before and after. Spring sowing season is very important for farmers.
