摘　　要：文章通过对通辽市地形、环境等物理条件进行综合分析,得出受地形影响,各天气系统越境时强度的大小变化。通辽市地形复杂,有山区,有平原,还有斜下冲积平原。分析过程从气流越山的物理量入手,详细分析气流的水平、垂直等变化,着重解释上升条件的物理因素对云雨的发展变化。结合实际情况,对各种天气系统进行逐个分析,旨在预报过程中,能较准确地把握降水量的预报,对提高预报准确率有所帮助。In this paper,we made a comprehensive analysis of Tongliao City＇s terrain,environmental and physical conditions,and obtained the change of size and intensity in various weather systems across the border,by the terrain.Tongliao City＇s terrain is complex,contained mountains,plains,as well as the ramp under the flood plains.Beginning of the physical quantity of flow over mountain,we made a detailed analysis of the airflow horizontal,vertical changes,to explain the effect of physical factors of rise conditions in the development and changes of clouds and rain.We analyzed various weather systems,aimed at in forecasting process,can more accurately grasp the precipitation forecast,help to improve forecast accuracy.
