摘　　要：利用自动气象站观测资料、Micaps数据资料,从环流背景、动力热力学诊断分析等方面分析2016年7月19—20日沧州地区暴雨特点。结果显示:在两高对峙的环流背景下,高低空形势的配合、黄淮气旋的生成和发展、本地湿层深厚且低空急流提供的源源不断的水汽供应和系统有利的动力条件是本次暴雨形成的重要原因。Based on the observation data of automatic weather station and MICAPS data,the characteristics of heavy rain in Cangzhou during July 19-20,2016 were analyzed from the circulation background,dynamic and thermodynamic diagnosis analysis and other aspects.The results show that under the background of the circulation of two high and two high confrontation,the important reasons for the formation of the rainstorm are the coordination of high and low altitude situation,the formation and development of the Huang-Huai cyclone,the continuous water vapor supply from the deep local wet layer and the favorable dynamic conditions of the system.
