The Beauty Meaning of Grain Rain

The good moral of Grain Rain is that the cold wave weather is basically over and the temperature rises rapidly.

In Grain Rain season, obvious rain often begins to appear in southern China, especially in southern China. Once cold air meets warm and humid air, it will often form a long rainy day. Huaihe river basin is a transitional zone between spring rain in the south and spring drought in the north. From the north of the Huaihe River in Qinling Mountains, the spring rain dropped sharply.

Grain Rain, which means "Rain gives birth to a hundred valleys", has seen an obvious increase in precipitation. The seedlings in the field are newly planted, and the crops in Xinzhuang need rain most. With sufficient and timely rainfall, cereal crops can thrive.

"when it rains, all the grains and fruits climb." The main feature of Grain Rain is the continuous spring rain, which is beneficial to grain growth. Rain produces hundreds of valleys, which embodies the agroclimatic significance of "Grain Rain". It is the reflection of ancient farming culture in festivals.

Meteorological change

Continuous spring rain is the most important feature of solar terms in Grain Rain. After the solar term in Grain Rain, the rainfall increases and the humidity in the air gradually increases, which is beneficial to the growth of crops. After entering the Grain Rain solar term, the precipitation in the middle and lower reaches of the Yangtze River and the south of the Yangtze River increased obviously, especially in South China. Once cold air meets warm and humid air, it will often form rainy weather for a long time.

The Huaihe River Basin in Qinling Mountains is basically the dividing line between the spring rain in the south of the Yangtze River and the spring drought in the north. From the Qinling-Huaihe River to the north, the spring rain decreased sharply. In the north, Grain Rain is a symbol of the "final frost". There are few cases of large-scale invasion of cold air into the south, but the cold air activities affecting the north have not stopped, and early thunder will appear in many places.
