What does Grain Rain mean?

Grain Rain means "Rain gives birth to hundreds of valleys", and it is Grain Rain when the sun reaches 30 on April 20th or 2 1 day every year.

In Grain Rain season, in the south of China, "a hundred flowers blossom", willows fall, cuckoos cry at night, peonies bloom and cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly, generally the average temperature in late April, except in South China.

Outside the northern and western regions, it reaches 20℃ to 22℃, which is more than 2℃ higher than that in the central region. In the eastern part of South China, there is often a high temperature above 30 for a day or two, which makes people feel very hot. Low-altitude valley areas have also entered summer.

Climatic characteristics of Grain Rain.

1, the Huaihe River Basin in spring drought is the transitional area between the spring rain in the south of the Yangtze River and the 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, "Qingming Grain Rain is often short of rain", which means that during these two solar terms, there is a shortage of rain. 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, so the rain is more expensive at this time.

2. The rainstorm entered the solar term in Grain Rain, and obvious rainfall often began in the middle and lower reaches of the Yangtze River and the south of the Yangtze River, 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. Strong convective weather wrapped in clouds and rain will not only bring disasters such as hail and thunderstorm, but also be accompanied by short-term, local rainstorm or torrential rain. 24-hour rainfall can reach more than 300 or 400 mm, resulting in river flooding and serious waterlogging, and long-term heavy rain will also lead to mudslides, landslides and other disasters.

3. Sandstorm According to the 24 solar terms, Grain Rain is the last solar term in spring. Grain Rain in late spring means that spring will end and summer will come. The large-scale invasion of cold air into the south is rare, but the cold air activities affecting the north will not stop. From the end of April to the beginning of May, the temperature is much higher than that in March, and the soil is dry and loose. The air layer is unstable, the high-altitude wind drops, the frontal cyclone is active, and the windy and dusty weather caused by * * * is more common. A wide range of floating dust weather, dark sky and falling yellow dust have eclipsed the poet's pictures of grass growing, flowers blooming and spring.

4. Strong convective weather Generally speaking, April-August is the peak period of strong convective weather in a year. 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.
