摘　　要：利用MICAPS和NCEP1°×1°再分析资料，对一次典型东北路径移动西南涡演变及产生的致洪暴雨进行研究。通过对低涡的生成源地、环流特征、移动路径、强度变化、生命史及所形成暴雨过程进行分析，指出影响低涡致洪暴雨的天气系统配置，为影响河南地区的低涡及致洪暴雨预报提供依据。Using the MICAPS data and NCEP1°×1° reanalysis data, one typical evolution of southwest vortex moving towards northeast, which caused flood-producing heavy rainfall was studied. By analyzing the features such as genesis, circulation characteristic, movement track, intensity during the genesis and moving process, lifetime and heavy rainfall cause, the allocation of influencing flood-producing synoptic system were offered to provide basis for forecasting vortex and flood-producing heavy rainfall in Henan province.
