摘　　要：利用常规气象资料、雷达资料等从影响系统、物理量场诊断等方面对2013年6月12日发生在漳州市的暴雨过程进行分析,结果显示这次暴雨过程是在500 h Pa高空槽和850h Pa低层切变共同影响下产生的,暴雨区与垂直速度所表现的上升区对应,并伴有高能高湿条件。雷达回波的"列车效应"以及暖平流+辐合,造成漳州部分地区强降水。模式降水预报检验结果表明,48 h T639降水预报有较好的参考价值。Using conventional meteorological data and radar data, this paper carried out an analysis on a rainstorm occurred in Zhangzhou on June 12 th,2013 from the perspective of the impact system and physical quantity. The result demonstrated that the rainstorm occurred under the influence of 500 h Pa upper trough and low level shear. Rainstorm area corresponded to the rising area shown by the vertical speed and accompanies high-energy and high-humidity conditions. The ＂train effect＂ of radar echo, warm advection and convergence contributed the heavy rainfall in some area of Zhangzhou. The results of pattern rainfall forecast indicated that the T639 rainfall forecast of 48 hours had a relatively high reference value.
