摘　　要：结合多普勒雷达产品特征对2007年7月18～19日烟台地区出现的一次区域性暴雨过程的中尺度雨团特征进行分析，结果表明：多个强降水雨团自西北向东南移过半岛是产生这次大暴雨的主要原因。冷锋带状回波与冷锋前方块状回波结合后迅速发展，有中气旋出现。700hPa干舌、500hPa弱冷平流和强上升区的存在是出现强对流天气的主要原因。Combined with the characters of Doppler radar product, the characters of a meso-scale rain group in a regional rainstorm process occurred on July 18^th - 19^th of 2007 in Yantai were analyzed. The most reason was several strong precipitation rain group move from northeast to southeast of peninsula. The echoes of strip shape of cold front integrated the echo of block before cold front and developed rapidly. And mesocyclone appeared. The dry air flow in 700 hPa, cold flow and puissant ascending flow in 500 hPa were the mairl reasons of strong convection.
