【Abstract】 Based on the typhoon optimal path data set from China Meteorological Administration during 2005 and 2020, and the Himawari-8 and FY4 satellites cloud image data, combined with the new technology of artificial intelligence, this paper applies deep learning models to typhoon vortex identification, typhoon location and intensity determination, typhoon intensity change detection, etc. To be specific, the new technology has been applied to develop a typhoon vortex identification model based on depth image target detection, a typhoon intensity intelligent determination model based on image classification and retrieval, and a typhoon rapid enhancement discrimination model considering the characteristics of time and space series. Tests with all the samples of vortices occurred in 2020 show that the correct identification rate of typhoon vortex with intensity reaching strong tropical storm or stronger is over 90%, the mean absolute error and root mean squared error of typhoon intensity estimation are 3.8 m/s and 5.05 m/s, respectively, and the comprehensive accuracy rate of annual independent sample intensity rapid enhancement estimation is 65.3%. The system realizes the automatic identification, positioning,intensity determination, and real-time intelligent tracking of tropical cyclones by using satellite images with high spatial and temporal resolution.更多还原
