What are the characteristics of the rainy season climate?

The rain solar term generally starts from February 18 or 19 and ends on March 4 or 5. The direct point of the sun is approaching 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 is becoming active and gradually moving northward.

At the same time, cold air is not to be outdone in the weakening trend, and it frequently competes with warm air, unwilling to quit its hegemony and refuse to take away the residual cold. ? At this time, the atmospheric circulation is in the adjustment stage, and the general trend of climate characteristics throughout the country is from cold in late winter to warm in early spring.
