摘　　要：利用ＧＭＳ卫星遥感资料，结合地面气象观测资料和中尺度每小时数值模拟，对１９９８年４月和２０００年４月发生的强沙尘大气演变过程进行了详细的分析，初步确定了影响我国的沙尘暴起始源地，并将我国的沙尘暴天气划分为Ｕ变化型（停滞型）和移动型（锋面气旋型等）．详细分析了低涡型沙尘暴和东北低涡型沙尘暴的发生。Using the satellite remote sensing data of GMS and the observational ground meteorological data as well as the hourly simulation results from MM5, we analyzed carefully the synoptic evolution of strong dust storm occurred in April 1998 and April 2000. We determined also the initial sources of dust storm influencing China; and classified them into daily variation (stagnancy)type and moving (frontal cyclone) type. The macro mechanism of occurrence and development of low eddy cyclone and northeast low eddy cyclone dust storms was analyzed in detail.
