China’s first successful typhoon observation test with large UAV

Yesterday, the China Meteorological Administration (CMA) and 12 units jointly carried out the first comprehensive observation test of typhoon with large UAV at high altitude in China and achieved a complete success.

on the afternoon of February 2, a high-altitude meteorological observation UAV carrying observation equipment took off from Boao airport in Hainan. After rising to a height of 10000 meters, it successfully dropped 30 radiosondes and completed CT scanning of the cloud system around typhoon senlak this year with millimeter wave radar. The observation data were transmitted back to the ground command system in real time. The UAV, Fengyun meteorological satellite, unmanned ship and other detection methods formed a three-dimensional observation, which provided an important reference for the determination of the center position of typhoon senlak.

according to reports, China’s annual economic losses caused by typhoons are about 29.5 billion yuan, and the lack of sea observation data limits the improvement of typhoon forecast technology. To this end, China Meteorological Administration launched the “petrel plan” in 2018, and selected the “pterosaur-10” large UAV to carry out the ocean integrated meteorological observation test. This test is a part of the “petrel plan”, filling in the gaps of China’s ocean comprehensive observation based on large-scale high-altitude UAV, and has important significance to improve the accuracy of typhoon forecast.
