| Abstract: | Using the infrared channel images detected by the FY-2 meteorological satellite,the research on the detecting and tracking of cloud systems is conducted.The whole life cycle,including forming,developing,and dissipating,are studied based on the method of adaptive threshold temperature.The splitting and merging of cloud systems are tackled based on the geographical overlapping of two consecutive infrared images,and some characteristic quantities such as threshold temperature,area,moving velocity,temperature,t... |
