| 摘 要： | 利用近几年来气象卫星对沙尘天气的监测结果,分析了影响北京地区沙尘天气的一些特征,得到以下结果:(1)影响北京地区沙尘的源地可分为3类:第1类沙尘起源于蒙古国南部地区,第2类沙尘起源于我国内蒙古地区,第3类沙尘起源于北京本地.(2)影响北京地区的沙尘路径大致有3条:第1条路径,蒙古国南部-内蒙古浑善达克沙地-河北省西北部-北京地区;第2条路径,蒙古国南部-内蒙古朱日和一带-河北省西部-北京地区;第3条路径,山西高原-河北-北京地区.(3)沙尘在移动过程中,强度是不断变化的.(4)大气环流是制约沙尘天气的直接原因.

| Abstract: | Some features of the dust weather affecting Beijing are analyzed. The results show three kinds of dust storm sources that influence Beijing. The first one is in the southern part of Mongolia, the second is in the Inner Mongolia, and the third is in Beijing area. The routes are mainly three. The first one is the southern part of Mongolia-the Hunshandake desert in the Inner Mongolia-the northwestern part of the Hebei Province-Beijing area, the second is the southern part of Mongolia-the Zhurihe area in the Inner Mongolia-the western part of the Hebei Province-Beijing area, and the third is Shanxi tableland-Hebei Province-Beijing area. The intensity of dust storms changes while they are moving. The direct reasons that control dust storm weather are atmospheric circulations. |
