On the afternoon of August 2, during the impact of this year’s 3rd typhoon Sinlaku on Hainan, an upper-air meteorological Unmanned Aerial Vehicle (UAV) lifted off from Boao Airport and dropped off 30 sondes, which carried out CT three-dimensional scan of the peripheral cloud system of the typhoon together with millimeter wave radar.
With the real-time vertical profiling observation data like temperature, humidity, air pressure, wind direction, wind direction and hydrometeor of the peripheral cloud system of the typhoon transferred to the ground commanding system, China’s first large scale marine and typhoon integrated observation experiment via drone has been rounded out, which has filled in the vacancy of China’s first marine integrated observation experiment based on upper-air large scale UAV.
According to Mr. Qian Chuanhai, Director of Typhoon and Ocean Meteorological Prediction Center of China Meteorological Administration (CMA), despite the steady progress of typhoon prediction level of China, the deficiency of marine observation data was a handicap to the research into typhoon generation principle and prediction technology development. The data from this experiment has provided crucial reference for locating the center of the typhoon, and borne significance to further ramping up China’s typhoon track and intensity prediction accuracy, and consolidating disaster preparedness.

Prior to that, the experiment team has conducted 4 drone flight observation experiments of varied meteorological environments and payloads as of June 25. It has harnessed myriad sounding approaches like Fengyun meteorological satellites, unmanned vessels, shuttle intelligent sounding, buoys, and carried out three-dimensional observation. This experiment is a significant achievement of China’s first marine integrated observation experiment based on upper-air large scale Unmanned Aerial Vehicle (Haiyan Project). The UAV and sounding payloads used in the experiment are independently developed by China.

According to statistics, typhoon imposes economic losses of 29.5 billion yuan on China each year. A raft of numerical weather prediction results show that aircraft dropping sounding data can obviously improve typhoon prediction. CMA activated Haiyan Project in 2018 and selected Yilong-10 large scale UAV to carry out the experiment with 12 units. Hainan Provincial Meteorological Service has reinforced coordination and provided potent meteorological support for the smooth operation of the experiment.

Mr. Li Liangxu, Director of Meteorological Observation Center of CMA and the commander-in-chief of Haiyan Project expressed that relevant departments will further improve the technical system, and provide solid groundwork for accurate monitoring, accurate prediction and elaborate services, as well as global meteorological services.
