What are the weather characteristics of rain solar terms?

As the temperature rises, the precipitation increases. In the Yellow River Valley, the birthplace of the 24 solar terms, the weather was cold before the rain, but there were snowflakes flying and the unpleasant rain dripped. After the rain, the temperature can generally rise above 0 degrees Celsius, with less snow and more rain. However, in the warm southern region, even in the dead of winter, rainfall is not uncommon.

In most parts of southern China, the average temperature during this period was above 10 degrees Celsius, with peaches and plums in bud and cherry blossoms in full bloom. It has indeed entered the climate spring. In addition to a few years, the frost period has come to an end.

It is timely to graft fruit trees and plant trees. After a dry winter, there are many droughts in spring all year round in South China, especially in the western part of South China, where "spring rain is as expensive as oil". In addition, the invasion of cold wave will cause strong cooling and snowstorm, which will do great harm to the old, weak and young animals. These should pay special attention to prevention.

Historical origin of rainwater

Wu Cheng's book "Twenty-four Solar Terms" in the Yuan Dynasty said: "The first month is aquatic in the sky, and spring is wood. However, people who grow trees must have water, so it rained successfully in beginning of spring. If the east wind melts, it will disperse into rain. "

Rain has two meanings, one is that the weather gets warmer and the precipitation increases gradually, and the other is that there is less snow and more rain. There are phenological descriptions in Yizhoushu, such as "Hongyan is coming" and "vegetation sprouting after rain".
