摘要
利用气象卫星资料对 2 0 0 2年春季北京沙尘天气成因及源地进行分析 ,得出 :我国北方地区连续数年的持续少雨以及 2 0 0 1年冬天以来的异常温暖是 2 0 0 2年北京沙尘天气频发的主要气候原因 ;2 0 0 2年春季影响北京的沙尘天气分别来源于蒙古国境内和内蒙古阴山地区及浑善达克沙地毗邻地区 ,前者所造成的影响明显大于后者。
The origin and the source region of the dust weather are analysed in this paper, and some conclusions have been drawn: the climate background for the formation of the dust storm included the drought which had continued for three years and the abnormal warm during the winter of 2001. The dust weather that affected Beijing came from Mongolia and Hunshandake sandy area located in the middle of Inner Mongolia, and the former area obviously exerted more intense influence than the latter area.
