Filling the blank of ocean observation data and improving the level of typhoon monitoring and forecasting
China's large-scale UAV typhoon detection test was successful
Beijing, August 3 (Reporters Liu Yi, Zhao Beijia) On the afternoon of August 2nd, during the impact of Typhoon No. 3 this year in Hainan, a large-scale high-altitude weather detection drone independently developed by China Hainan Boao Airport took off, which took 4 hours to successfully complete the comprehensive meteorological observation mission of the peripheral cloud system of Typhoon "Senrak". This marks a major breakthrough in this field for China and is of great significance for typhoon detection, forecast and warning.
This large-scale weather detection drone successfully dropped 30 radiosondes and, together with millimeter-wave radar, carried out a "CT-style three-dimensional scan" of the cloud system outside Typhoon "Senrak". Groups of temperature, humidity, air pressure, hydrometeor and other observation data over the ocean and sea surface are transmitted back to the ground command system in real time. China's first high-altitude large-scale UAV ocean and typhoon comprehensive observation experiment was a complete success, filling the gap in the comprehensive ocean observation based on high-altitude large UAV.
This is an important achievement of China's high-altitude large-scale UAV marine comprehensive meteorological observation experiment (referred to as the "Haiyan Project"). The China Meteorological Administration launched the "Haiyan Project" in 2018. It selected the "Pterosaur-10" large-scale UAV to conduct tests with 12 units including Chengdu Aircraft Industry Group Co., Ltd. The Hainan Meteorological Bureau strengthened airspace coordination and provided strong meteorological guarantee for the smooth development of the test.
According to Qian Chuanhai, director of the Typhoon and Marine Meteorological Forecast Center of the China Meteorological Administration, although the level of typhoon forecasting in my country has steadily improved in recent years, the lack of marine observation data has restricted the research on typhoon generation mechanism and the improvement of forecasting technology. The data from this comprehensive marine exploration test provides an important reference basis for forecasters to determine the center position of the typhoon "Senrak", which is of great significance for China to further improve the accuracy of the typhoon path and intensity forecast, and to strengthen the first line of defense for meteorological disaster prevention and mitigation. .
According to statistics, typhoons cause about 29.5 billion yuan in economic losses to China each year. The results of various numerical models prove that the sounding data such as aircraft drop can significantly improve the typhoon forecast.
Previously, the test team has carried out 4 drone flight observation tests in different meteorological environments and loads since June 25. Fengyun weather satellites, unmanned ships, round-trip intelligent soundings, drifting buoys and other detection methods cooperate with them. , Carry out stereo observation.
Li Liangxu, commander-in-chief of the "Haiyan Project" and director of the Meteorological Observation Center of China Meteorological Administration, introduced that the next step will continue to improve the technical system, establish a large-scale UAV full-chain observation business and typhoon detection business system objectives, and open up observations to business applications. , To lay a solid foundation for achieving the goal of "precise monitoring, accurate forecasting, and fine service" and better development of global meteorological services.
Zhang Xuefen, head of the test technology team and deputy chief engineer of the China Meteorological Administration Meteorological Observation Center, said that the UAV and all detection payloads used in the test have completely independent intellectual property rights.
