What are the characteristics of "rain" in the 24 solar terms?

The rain, which indicates the beginning of precipitation, is gradually increasing. Rainwater has two meanings: first, the weather is warming up and the amount of precipitation is gradually increasing, and second, in terms of the form of precipitation, there is less snow and more rain.　　

Rain is the second of the 24 solar terms. Every year around the 15th day of the first month (February 18-20, Gregorian calendar), when the sun's yellow longitude reaches 330 degrees, rain is the rain of the 24 solar terms. At this time, the temperature rises, snow and ice melt, and precipitation increases, so it is named rain. The rainy season period generally begins on February 18 or 19 and ends on March 4 or 5, according to the Gregorian calendar. Like Guyu, Xiaoyue and Daxue, Yushui is a festival that reflects the phenomenon of precipitation.
