According to Liu Jianke of the Hunan Provincial Meteorological Observatory, Hunan maintained sunny and hot weather before the 20th. On the 21st, cold air penetrated southward, and there were small fluctuations in the sky. Hunan ushered in a process of cooling and precipitation from west to east. On the 21st, the cloud system changed, and precipitation occurred in Xiangxi and Xiangbei. 22-23 days was the strongest period of precipitation during the process. Due to the obvious rising temperature in the previous period, the high temperature momentum is strong, and the unstable energy in the air is high, so the 21-23 day process will be accompanied by thunderstorms, strong winds and other strong convective weather.
Since this year, rainfall in Hunan has continued to be less. Therefore, the precipitation process will certainly help to improve soil moisture, and it is expected to ease the drought situation in the province to a certain extent.
