| 摘 要： | 利用1951-2010年地面气象月报资料,根据北京发生沙尘天气情况下周围观测站发生沙尘天气的概率空间分布推断影响北京地区沙尘天气移动路径的方法,得到影响北京地区沙尘天气的主要通道是张掖—民勤—鄂托克前旗—大同—北京和锡林浩特盟二连浩特市—浑善达克沙地西部—张北—北京这两条路径之间。该区域内的巴丹吉林沙漠、乌兰布和沙漠、毛乌素沙地和浑善达克沙漠是影响北京地区沙尘天气的主要沙源地。

| Abstract: | The frequency of sand-dust weather is decreasing in general,especially the duststorm,in the Past 60 years.The meteorological data in 1951-2010 were used to analyze the transportation path of sand-dust weather affecting Beijing region.The result shows that most of sand-dust weather affecting Beijing has passed through a region in North China.The north boundary of the region is from Zhangye and Minqin of Gansu Province,Otog Front Banner of Inner Mongolia,Datong of Shanxi Province to Beijing,and the south boundary is from Xilin Hot of Inner Mongolia,Hunsandake desert,Zhangbei of Hebei Province to Beijing. |
