摘　　要：利用2006年8月3日—11日CloudSat卫星的云反演资料,探讨了热带气旋"桑美(2006)"在形成期、发展成熟期和减弱期不同部位云中冰粒子的垂直分布规律。结果表明:星载雷达扫过热带气旋"桑美(2006)"不同部位时,云中冰粒子主要分布在5~16.5km高度;冰粒子等效半径随高度递增而递减,大值区主要分布在冰云下部;冰粒子数浓度随高度递增而递增,大值区主要分布在冰云上部;冰水含量的垂直分布呈单峰或双峰特征;星载雷达监测到的该热带气旋不同部位的冰粒子等效半径、冰粒子数浓度、冰水含量的最大值分布范围分别为107.9~177.7mm、123.8~827.9粒×L^(-1)、211~2858mg·m^(-3),最大值出现高度存在差异。Using the retrieved data from Cloud Sat during August 3-11,2006,the vertical distributions of ice particles in the clouds of different parts of tropical cyclone（TC） Saomai（2006） were analyzed,in their formation period,development-tomature period and weakening period.The results are as follows.When the space-borne radar swept through different parts of TC Saomai（2006）,ice particles in the clouds mainly distributed from the height of 5 to 16.5 km.The ice particle effective radius（re） reduced with increasing altitude and the large particles were mainly concentrated at the bottom of the ice clouds.The ice particle number concentration（Cin） increased with increasing altitude and large particles were mainly at the top of the ice clouds;the vertical distribution of the ice water content（Ciw） had a shape of unimodal or bimodal.The heights of the maximum re,Cin and Ciw were different from each other,and the ranges of the maximum what for re,Cin and Ciw were 107.9~177.7 μm,123.8~827.9 L^（–1） and 211~2858 mg×m^（–3）,respectively.
