"The drought is not over, and the rain will not stop." Hubei has implemented the aircraft manually 15 times

The Yangtze River Daily Da Wuhan client August 25th "The plane is ready to fly to the place where the operation conditions are available at Liuji Airport in Xiangyang." On the 25th, the high temperature and intensity of our province continued to decrease, accompanied by the outer airflow and cold of the typhoon and cold. There are also cloudy weather and decentralized showers. Liu Jian, deputy director of the Hubei Provincial Office of Manual Weather, told the Yangtze River Daily that the personnel, equipment and aircraft of the province's artificially influencing weather operations are standing at any time. We must seize all weather conditions for artificial rainfall operations.

The province has implemented 15 artificial rainfalls in the province 15 times

There are many ways to increase artificially rainfall: aircraft, rockets, high guns and smoke furnaces. Among them, the aircraft is the best solution. It can directly broadcast catalysts such as silver iodide into the scheduled parts of the cloud, which has the advantages of uniform broadcasting, large operating area, and wide influence. According to Liu Jian, in addition to a artificial rain increase operation aircraft rented in our province, the China Meteorological Administration also urgently coordinated a national high -performance artificial artificial rain increase operation aircraft to help our province. 15 sorteds to cooperate together to increase the rain and relieve the drought.

It is understood that from 8:00 on August 15th to 18:00, 15 artificial rainfall operations in the province in the province, with a cumulative flight length of 37.54 hours; 326 artificial rainfall operations on the ground. Square kilometers. Under the joint influence of the weather system and artificial rainfall operations, Shiyan, Xiangyang, Enshi, Yichang, Shennongjia, Jingmen, Suizhou, Xiaogang, Huanggang, Huangshi, Wuhan, Ezhou, Xianning, and 13 cities and stations appeared in a total of 701 stations, including 701 stations The rainfall exceeds 10 mm, 334 stations exceed 25 mm, and 106 stations reach more than 50 mm. 6 stations are over 100 mm. The rainfall is mainly concentrated in Shiyan, Shennongjia, Xiangyang, Suizhou, Huanggang, Yichang, Xianning and other places.

Artificial rainfall operation is accurate to "fixed -point timing quantity"

Under the joint influence of the airflow of the typhoon and the weak cold air, the province is mainly cloudy, and the forecast has the process of rainfall. Liu Jian said that in the future, it is suitable for manual rainfall operations. "Artificial rain increases needs to meet the following 4 conditions: 1. The cloud system of the operating area should be developed to a certain thickness. This thickness is generally greater than 2 kilometers; The height is below 2 kilometers; 3. The cloud area should be wide and the area must reach dozens of square kilometers; 4. There must be a certain amount of upside. Only when the water vapor is sufficient in the cloud and has the potential of precipitation, can we have the opportunity to use manual intervention to toward the manual intervention. Driving an appropriate amount of catalysts in the cloud to achieve the purpose of precipitation. Because the weather system is changing at any time, the Provincial Meteorological Bureau organizes experts to conduct video decision -making providers every day. Operations and ground homework plan for scheme design and dispatch deployment, scientific assignments, precision operations, and safety operations. "

Once the conditions meet the conditions, the ground -people shadow operators and equipment will be squatting at the operating point. When the clouds come over, the conditions of the cloud will be fully operated immediately. Relatively speaking, the conditions for airplane human figures are more stringent. "Flight is affected by the environment. If it is strong, it is not good for the aircraft to take off and land. First of all, it is necessary to ensure that it can fly, and then to the areas that are conducive to operating conditions. "At present, the main off -airport of the shadow aircraft in our province is Xiangyang Liuji Airport.

Liu Jian said that the shadow operation is not as simple as everyone thinks. With the improvement of the level of meteorological modernization, the improvement of detection and forecasting and prediction capabilities is very accurate. " The plan, the operating point, the height of the launch, the volume, the amount of bullet, the catalyst to the cloud body, is very clear, and the fixed -point and quantitative is to reflect the precise operation. "

"The drought is not over, the rain will not stop"

As early as June, the experts of human shadow operations in our province had deployed artificial rainfall ground work. "Artificial rainfall has always been a normalized work for the masses to do practical things. Under the premise of natural precipitation Improving the requirements of air quality and ecological environmental protection. At that time, drought was not so serious, mainly on ground operations. "

At present, our province is in a state of emergency response at the fourth level of drought resistance. The province's 16 cities (states) 54 counties (cities) start a drought resistance response. On August 22, the General Office of the Provincial Government held a special meeting to put forward specific requirements for the recent drought -resistant manual rainfall operations and the harvest of Baoqiu grain. It is clearly mentioned that it is necessary to carry out operations on heavy dry areas, long dry areas, main food producing areas, and human -animal drinking water. Liu Jian said that in accordance with the requirements of the Provincial Party Committee and Provincial Government, the meteorological department of the province will go all out and grasp the opportunity to do a good job of manual rain and drought and drought. The airspace allows operations to carry out homework. The drought will not end, and the rain will not stop. "From 8:00 on the 25th to 18:00, the province implemented an artificial rainfall operation of airplanes in the province. The flight time was 3.2 hours. , Huangshi, Ezhou, Xianning, Xiantao, Tianmen, Jingmen and other places; carried out the ground artificial rain increase operations (Shennongjia, Xianning), and the cumulative area of ​​the open space affects about 33,500 square kilometers.
