Qi Zhongyu

The rain solar term generally starts from February 18 to 20 and ends on March 4 or 5. During the rainy season, 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, and the rainfall gradually increases, but the rainfall level is mainly light rain or Mao Mao rain.

In the rainy season, the northwest and northeast of China are still not out of the category of winter. Judging from the average temperature in February, the monthly average temperatures in Lanzhou, Xining, Urumqi and Shenyang are-65438 0.0℃, -3.9℃, -9.7℃ and -6.9℃ respectively. It can be seen that these places have not got rid of the cold in winter, the weather is still dominated by cold, and the precipitation is dominated by snow.
