Focus on high temperature and drought!The China Meteorological Administration implements the "three firsts" of manual rainfall operations!

On September 6, the reporter learned from the September press conference of the China Meteorological Administration that in response to the continuous high temperature and drought situation of the Sichuan Basin and the middle and lower reaches of the Yangtze River in the past period of time, the China Meteorological Administration attaches great importance to and quickly deployed. The weather center and the meteorological departments of the weather center adhere to the "one game of a nationwide", the multi -departments coordinate, upstream and downstream linkage, and overall the national resource -to -high -temperature dry area to carry out artificial rainfall operations in the country to achieve good results.

Main measure

The first is to carefully organize and mobilize operating power to support the dry area. The China Meteorological Administration has been mobilized to deploy, and organizes various places to actively carry out artificial rainfall operations. With the support of the National Development and Reform Commission and the Ministry of Finance, on August 17, 23, 25, and 26, four national high -performance rainfall aircraft were sent from northeast, northwest and other places to Xiangyang, Chongqing, Nanyang, Henan, and Shaanxi in Hubei. Ankang and other dry areas support raindrops. Select a number of technical backbones to go to the field to ensure operating aircraft to ensure flight safety. In addition, the relevant manufacturers also called two large drones for the first time to implement rainfall and drought and fire in Chongqing, which effectively made up for someone's airplane operation.

The second is scientific research and judgment, and give full play to technological advantages. The China Meteorological Administration actively uses advanced technical means such as Fengyun series meteorological satellites, weather radar, high -performance rainfall aircraft and drone, numerical forecast mode and other advanced technical means to give full play to the effectiveness of scientific research projects and modernization construction. Meteorological departments at all levels are closely collaborated, scientific research and judgment operations Conditions, precise design operation plans, safe implementation of rain increase operations, and objective evaluation of operational effects. Aiming at the severe drought of the water level of the Danjiangkou Reservoir in the Danjiangkou Reservoir in the South -to -North Water Diversion Project, on August 27, the China Meteorological Administration organized the three national shadow aircraft in Nanyang, Xiangyang, and Ankang to carry out a large -scale cross -regional open space in the Huishui area of ​​Danjiangkou Reservoir. Joint rainfall operations, artificial rain increase operations have increased the reservoir capacity, and played a positive and effective role in alleviating drought and energy conservation. Since August 25, there have been high temperatures that have caused forest fires in many places in Chongqing and Sichuan. The China Meteorological Administration has urgently sent a high -performance rainfall aircraft in Chongqing to jointly deploy drones in Zigong, Sichuan to carry out artificial rainfall against fire and dry areas. During the operation, rainfall occurs after the operation. It can be said that artificial rainfall provides a strong guarantee for the fire work of the Sichuan -Chongqing area.

Achievement

One is the first time, that is, for the first time to carry out a large -scale artificial rainfall operation in the southern flood season. Whether it is the research and judgment of the operating conditions, the grasp of the timing of the operation, and the guarantee of the operation safety, they all face unprecedented challenges. Water engineering has carried out rain increase operations. As of August 31, a total of 16 manual rainfall operations were implemented around the Huishui District of Danjiangkou Reservoir, and accumulated for 45 hours; the first time it organized two large drones to carry out drought resistance and artificial rainfall operations. The application of new technologies and new equipment to some extent fills gaps in human -machine operations.

The second is that the large -scale artificial rain increase operation effectively alleviates high temperature and drought, and has played a positive role in agricultural production, energy insurance, forest fire prevention, human health, and water safety. According to statistics, from August 1st to 31st, for the high -temperature dry area of ​​the south, a total of 75 artificial rainfall operations were implemented and accumulated for 211 hours. It reached 1.45 million square kilometers. Large -scale artificial rainfall operations provide solid weather guarantee for alleviating high temperature and drought conditions, increasing the water storage capacity of the reservoir, and ensuring that autumn grains are stable and harvested.
