摘　　要：利用常规气象资料和红外云图资料,对2013年7月14-16日呼伦贝尔市一次暴雨天气过程进行成因分析。结果表明:此次降水的环流形势为典型的副热带高压与西风槽相互作用的暴雨天气形势,系统垂直发展旺盛且坡度陡直,使得中低层影响系统始终处于上升运动区;地面气旋的辐合作用和辐合线的抬升作用是这次暴雨产生的触发机制;中低空急流的耦合配置为对流发展创造了有利条件,同时低空急流为这次暴雨天气提供了源源不断的水汽输送;南北长达数千公里带状云系上的对流云团强盛发展与暴雨落区对应很好。Using of conventional meteorological data and infrared cloud image data, the causes of rainstorm weather process was analyzed in Hulunbuir on July 14-16, 2013. The results showed that： the circulation situation of the precipitation was the situation of rainstorm of the interaction with typical subtropical high and westerly trough, system of exuberant vertical development and steep slope, made the lower layer system to be always in the ascending motion area; The rainstorm resulting triggering mechanism was surface cyclone convergence and the line lifting; The low-level jet created favorable conditions for the development of convection, and low-level jet provides everfount vapor transport for the rainstorm; The corresponds conrresponded very well between convective cloud strong developed of south for thousands of kilometers banded cloud and drop zone of heavy rain.
