摘　　要：利用常规气象资料和合肥多普勒雷达回波,分析了2004年5月21日巢湖市降雹的环流背景、回波发展演变过程。结果表明,烔炀至巢湖市沿湖一线短时间内连续两次遭受冰雹袭击可能与湖陆交界的特点有关,是湖陆风与天气系统叠加和共同作用的结果。Based on the meteorological data and the Doppler radar data of Hefei, general circulation background, echo＇s development and evolution of the hail during 21 May 2004 in Chaohu, Anhui Province are analyzed. The results show that continued hail along the Chaohu lake in the short time period is closely related to its position between land and lake and caused by the superposition of mesosystem and the land and lake breeze.
