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.
