What are the three periods of rain?

Three periods of rain, one is Rex offering fish; Second, wait for Hongyan to come; Third, vegetation is sprouting.

In ancient China, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third-class grass sprouted. " The twenty-four solar terms are based on the Yellow River Basin. Before it rained, it was cold, but snowflakes were flying and unpleasant rain was falling. After the rain, the temperature can generally rise above 0℃, and the snow gradually decreases and begins to melt.

In this solar term, otters start fishing and put the fish on the shore like sacrifices before eating; Five days later, the geese began to fly back to the north from the south; In five days, in the "moist and silent" spring rain, the spirit of the sun rises everywhere in the vegetation and begins to sprout. Since then, the earth has gradually begun to show a thriving scene.

Rainwater climate change

Rain solar term means the beginning of rainfall, but the rainfall level is mainly light rain or Mao Mao rain. In the rainy season, the direct point of the sun gradually approaches the equator from the southern hemisphere.

At this time, in the northern hemisphere, the sunshine hours and intensity are increasing, the temperature is rising rapidly, and the warm and humid air from the ocean begins to be active and gradually advances northward; At the same time, cold air is not to be outdone in the weakening trend, and it frequently competes with warm air to form rainfall.
