Rain and solar terms make the sun shine, okay?

On rainy days, there is no rule that it must rain, and it is good whether there is sun or not. Rain is the second of the 24 solar terms in a year, and it is still early spring. Although it's called rain, it's not rainy yet. Rain and no rain are normal phenomena. It doesn't have to rain, but it's not good when the sun shines.

Rain solar term means that it begins to rain, and the rainfall will gradually increase at this time. In the Yellow River valley, the birthplace of the 24 solar terms, the weather was cold before it rained, but it was snowing and raining hard. After rain, the temperature can generally rise above 0℃. At this time, the snow will be relatively reduced, but the rain will be more and more, and the frost period will end. 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 in various parts of China is the transition from cold in late winter to warm in early spring.
