Characteristics of solar terms in Grain Rain Brief introduction of solar terms in Grain Rain

1, Spring Drought: Huaihe River Basin is a transitional area between spring rain in the south of the Yangtze River and spring drought in the north. From the vicinity of Huaihe River in Qinling Mountains to the north, the spring rain decreases sharply. As the saying goes, "Rain is always scarce in Qingming Grain Rain", which means that rain is scarce during these two solar terms. During Grain Rain, people in Hainan Island, western Sichuan, western Guangxi, northwest China and north China are more eager for rain. Generally speaking, there are many sunny days, strong sunshine, large evaporation, windy sand and dry air, and the rain at this time is more expensive as oil.

2. Rainstorm: When Grain Rain entered the solar term, the middle and lower reaches of the Yangtze River and the south of the Yangtze River often began to be obviously rainy, especially in South China. Once cold air meets warm and humid air, it will often form rainy weather for a long time, and it will enter the annual first flood season.

3. Strong convective weather: April-August is the peak of strong convective weather in a year around Grain Rain. In May, severe weather such as thunderstorms, hail, strong winds and tornadoes will increase significantly in many areas in the south. Lightning protection, hail suppression and wind protection are put on the agenda.
