中文摘要: 利用FY2卫星云图分析系统的各项分析功能，结合常规观测资料对热带气旋北冕的天气形势、云图演变以及路径变化、风雨情况等进行了分析。结果表明，副热带高压摆动，中纬度西风小槽东移，低层西南气流加强和减弱是“北冕”出现两次北抬和一次南折的直接原因；对流云团的发展和减弱对应低层西南气流的加强和减弱；强降水与云顶亮温的最低值中心及强度密切相关，而云团面积和云顶亮温与强降水也有很好的对应关系，其中发展的云系是强降水发生的信号。FY2卫星云图分析系统较好地分析了“北冕”整个过程的变化特点，对于短时临近预报有较好的辅助作用

Abstract:With the conventional observational data and the functions of FY2 satellite cloud image analysis system 　 the tropical cyclone Kammuri is studied including weather situation, cloud evolution, path changes, rainfall and winds, etc. The results showed that the routes of “Kammuri” were twice northward and once southward, all these were closely related to the swing of the subtropical high, the eastward shift of the small westerly trough in the mid latitude and the strengthening and weakening of low level southwest flows; while the development and reduction of convective cloud cluster were better corresponding to the strengthening and weakening of low level southwest airflows. There is a good relationship between the heavy precipitation and the center of cloud top brightness, as well as its lowest intensity, and it is also closely related to the cloud size and cloud top brightness temperature with heavy precipitation, in which the development of cloud systems is a good signal to heavy precipitation. The FY2 satellite image analysis system is a good supporting tool for the short term nowcasting due to its better analyzing the characters of “Kammuri”.
