摘　　要：“５．５黑风暴”是一次罕见的严重气象灾害。根据极轨气象卫星资料分析认为：沙尘主要源自内蒙古巴丹吉林沙漠及其西北部戈壁地区的松软地表；强冷空气与其前部发展旺盛的中尺度对流系统是沙尘卷入空中的主动力；特殊地形环境对本次过程的形成起到了重要作用；同时，首次发现本次黑风暴天气过程中有东西两个含沙量较大的沙尘暴核心区域；云图上反映，沙尘暴区域反照率介于地表与云系之间，密度较均匀，边缘轮廓较整齐，内部可清晰看到类似颗粒状结构。Hardly appear such severe ineteorological disaster as“5.5 Dark Storm”,By meteorological al polar -orbiting satellite data .We think basically that dust came mainly from the Badanjilin Desert in In-ner Mongolia and the soft ground in the north -western gobi desert.Getting the power from strongcold air and its prosperous mesoscale convective system ahead,also under the special terrain and sur-rouding dust was drawn into air.It is at the first time that we find the east and west two dust devil core areas during this dark storm process,On the cloud chart,we can see the albedo,which had well-distributed density,regular edge and the clear peiled-structure inside,was between teh surface and the cloud system.It is very important to analyse the process for using the life meteorological satellte data and forecasting dark storm.
