中文摘要：
针对源区起沙的不确定性，整理并选取了国际上最具代表性的几种起沙方案，结合中尺度气象模式MM5V3．7输出的高分辨率气象资料，将其应用于东亚地区一次强沙尘暴天气过程的源区起沙模拟研究，利用地面观测实况和卫星监测图像资料，比较了它们对东亚起沙源的模拟效果和差异。结果表明，两种起沙方案的模拟效果较好且性能稳定。
英文摘要：
In view of the uncertainty of dust emission in source regions, several representative dust-emis-sion schemes are applied to simulate the dust emission by wind erosion during a strong dust stormweather process in East Asia, using the high-resolution output from MM5V3.7. The simulated results arecompared with the surface observations and the satellite images, and the differences among these simula-ted schemes are also compared.Results show that two schemes have better simulation effect and steadierperformance.
