Abstract: The simulative cloud image, made from the mixing ratios of cloud liquid water, rain water, ice crystal, snow, graupel which were outputted by the Mesoscale Model MM5, resemble the GMS satellite infrared image very well and also show the cloud evolution of typhoon Winnie from tropical cyclone to extratropical cyclone after landing. The simulated image, which provide the three-dimensional distribution of water contents of cloud, can make up the insufficiency of satellite observation which can only examine the top of cloud.

Key words: typhoon, modeling, cloud image

摘要： 利用高分辨率中尺度数值模式输出的大气中云水、冰水、雨水、雪水成功地模拟出1997年登陆台风Winnie的云系结构。模拟云图与气象卫星实际观测的台风云图非常相似。由于模拟云图可以给出大气中不同形态水物质的三维空间分布，弥补了卫星只能观测云顶表面的不足。模拟云图揭示出了台风云系中的中尺度云带以及台风Winnie登陆后从热带气旋变性为温带气旋过程中云系结构的变化。
