Abstract: Using the retrieved data from CloudSat 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-to- mature 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.
