Abstract:The uprush cloud top is a dome like protuberance on the rolling stock, which often has strong weather changes, and affects the aviation operation safety. Although the sensitivity of detecting strong convection by weather radar is high, the detection range is limited, and the satellite can detect strong convection in a large range for a long time without the limitation of terrain.Himawari-8 geostationary meteorological satellite can identify the uprush cloud top by the method of water vapor channel and infrared channel difference method, IRW-texture method and local minimum method. The experimental results show that the local minimum method can identify the upthrust cloud top more accurately and objectively than the other two methods.
