Today, the China Meteorological Administration, the China Meteorological Administration, the government in gansu province on January 6, jinchang jinchuan airport held a joint "showers - Ⅰ" weather modification drone first flight ceremony. At about 15:30, the drone took off. After take-off, the ground control system shows that the functions of anti-icing, atmospheric detection and catalyst seeding of the drone are normal, the system is stable and the performance meets the requirements of the project. With the drone landing smoothly, the maiden flight was a complete success.
It is understood that with the current artificial precipitation cloud-seeding rockets fired (snow) main way of the ground, burning furnace smoke on the ground and the man-machine seed precipitation enhancement compared to catalyst, drone precipitation (snow) has good mobility, long operation time and low safety risk and high execution efficiency, airborne data real-time transmission characteristics, can solve the artificial precipitation (snow), high operation cost, operation time and space by security restrictions, homework means a single, more practices a series of problems, such as three-dimensional extent.
Yu Yong, deputy director of the China Meteorological Administration, said that the use of large drone to carry out weather modification has filled the gap in China's large-scale drone to artificially increase rain (snow), which marks the obvious improvement of the weather modification ability, and has an important role in supporting the ecological civilization construction, poverty alleviation and rural revitalization. The success of this large-scale drone rain-enhancing (snow) experiment will not only improve the efficiency of the rain-modifying (snow) operation, but also further bring into play the benefits of the weather modification capacity construction project in Northwest China, and play a leading role in the demonstration of the whole country.
In recent years, Gansu Province has carried out a series of experimental research projects on artificial precipitation (snow) in the Qilian Mountains. The experimental results show that the Qilian Mountains, located in the northern margin of the Qinghai-Tibet Plateau, are rich in cloud water resources, with an average annual water vapor input of 88.54 billion cubic meters. However, under natural conditions, the proportion of water resources converted into precipitation in the air is less than 15%. If artificial precipitation (snow) is implemented in the Qilian Mountains, the annual precipitation can be increased by 15% at most theoretically, and the development potential of cloud water resources is relatively objective. It is estimated that when artificial precipitation (snow) increases by 10% in Qilian Mountains, the comprehensive benefit of Hexi Region can be increased by 5.3%. When the rainfall increase (snow) increases by 20%, the comprehensive benefit of each basin in Hexi Corridor increases by 12.5%.
In the next step, the China Meteorological Administration (CMA) and the government of Gansu Province will further strengthen cooperation and include a comprehensive application system of large-scale unmanned aerial vehicle weather modification into the 14th Five-Year Weather Modification Development Plan.
