Rain in the 24 solar terms

Rain is the second of the 24 solar terms.

The rain solar term generally starts from February 18 to 20 and ends on March 4 or 5. In rainy and solar terms, the direct point of the sun is gradually approaching the equator from the southern hemisphere. At this time, the sunshine hours and intensity in the northern hemisphere are increasing, and the temperature is rising rapidly. Warm and humid air from the ocean becomes active and gradually pushes northward to meet with cold air, forming rainfall. The rainy season is changeable, which is one of the seasons with the most cold wave processes in the whole year, with cold and hot, warm and cold at first.
