Why does it rain every day this year?

1. From the perspective of climate:

The Gregorian calendar is a rainy solar term around February 18 every year, when the sun reaches 330 degrees of the yellow meridian, it is a "rainy" solar term. Rain has two meanings. First, the weather is getting warmer and the precipitation is gradually increasing. Second, in the form of precipitation, there is less snow and more rain. The twenty-four solar terms say, "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. "

In ancient China, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third, wait for the grass to sprout. " 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.

The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5.
