What are the climatic characteristics of rain solar terms?

The temperature rises rapidly, and the warm and humid air from the ocean becomes active and gradually moves northward. The rainfall is increasing gradually, but the rainfall level is mainly light rain or Mao Mao rain.

Snow is an important symbol of winter, and it is still snowing in some parts of northern China, and it is still very cold. The solar term with the heaviest snow all year round in the middle and lower reaches of the Yellow River is neither "light snow and heavy snow" nor "slight cold and severe cold" (because the temperature was low at that time and there was less water vapor in the atmosphere), but the "rain" solar term in the spring of late February.

The southwest of the south of the Yangtze River and most parts of the south of the Yangtze River are all scenes of early spring, with warm sunshine, wet and cold in the morning and evening, and green fields and warm water along the river. South China is full of spring and flowers are in full bloom. Spring scenery is everywhere in southern Yunnan. Twenty-four solar terms: "In the first month, water is born every day. Spring belongs to wood, but there must be water for those who grow wood, so there is rain in beginning of spring. If the east wind melts, it will disperse into rain. "
