摘　　要：运用常规天气观测资料和九三新一代多普勒天气雷达资料对2011年5月28日黑龙江省西部的强对流天气进行综合分析。结果表明:此次天气过程产生于下层暖湿、上层干冷的环境中。急流的干湿输送作用和逆温层的阻隔作用,为本次过程的对流发展提供了能量储存。冷锋和925hPa气压槽的辐合作用是本次过程的触发机制,低抬升凝结高度、强垂直风切变有利于强对流天气的发生、发展。Using conventional observation and CINRAD data, the strong convective weather happened in the western of Heilongjiang Province on May 28, 2011 was analyzed. The results show that the weather occurred in conditions with lower warm and humid, upper cold and dry. The water vapor transportation of jet and separating effect of the inversion layer provided energy storage for the convective development. The cold front and the atmospheric convergence of trough on 925 hPa were the trigger mechanism of the process. The low lifting condensation level and the strong vertical wind shear is conducive to the occurrence and development of the severe convective weather.
