摘　　要：利用常规气象观测资料、中小尺度自动站资料、FY-2D卫星资料、多部多普勒雷达资料对2013年春季的一次强对流天气过程进行了分析。结果表明,此次强对流过程是发生在中高层干冷、低层暖湿的较强不稳定环境中,低层强烈的辐合触发不稳定能量的释放,激发中小尺度系统发生发展;强对流天气发生发展的热力动力条件呈现明显的中尺度天气特征;不同雷达回波特征可以清楚地判断冰雹、雷雨大风等中小尺度天气的发生发展。Based on the conventional meteorological data,meso-micro automatic station data,FY-2D satellite data and Doppler radar data,the strong convective weather process in the spring of 2013 was analyzed.This process occurs in a strong unstable environment where dry and cold in high level,but wet and warm in low level.The stong convergence in lower level triggers the release of unstable energy,stimulating the development of the meso-micro scale system.The result indicates：the dynamic and thermal conditions of the occurrence and development of strong convective weather present obvious mesoscale weather characteristics ; and the occurrence and development of mesoscale weather such as the hail and thunderstorm weather can be judged by different radar echo characteristics.
