The recent high temperature in Hunan is conducive to the harvesting of summer grain, and the precipitation will cool down on the 21st.

In the first two days, the highest temperature in Hunan Province was nearly 37 °C, and the hot weather will continue this day and tomorrow. From the 21st onwards, Hunan ushered in the process of cooling and precipitation from west to east. Rainwater has a certain help to improve soil moisture. At the same time, it is accompanied by strong convection such as thunderstorms and strong winds. All localities should pay attention to catching the harvesting crops in summer and ensuring that the particles are returned to the warehouse.

The glare of the sun, the hot temperatures, baking Sanxiang land. In recent days, the highest temperature in most parts of Hunan Province has entered the 30°C category. The highest temperatures of Cili and Shimen have risen to 36.8°C. The feeling of “hot summer” is especially strong. In meteorology, once the daily maximum temperature reaches or exceeds 35 degrees, it is called high temperature day. In this way, high temperatures have occurred in parts of Hunan. According to the Hunan Provincial Meteorological Observatory, before the 20th, the highest temperature in the province will reach 35 °C or above, especially today and tomorrow, the highest temperature in the province is nearly 37 °C, and the high temperature is higher than the waves. The sun is strong. Today's Changsha UV index can reach 4, and it is recommended that the public friends try to reduce their outings during the afternoon to avoid sunburn.

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.
