摘　　要：利用2002～2004三年5～8月郑州714CD多普勒雷达回波资料,以90km内向郑州方向移动的回波强度Z≥50dBz、高度H≥9km的回波和郑州附近新生的50dBz以上强对流回波为研究对象,通过分析雷达回波,找出了雷暴外流边界和郑州强对流天气的关系,并和无外流边界出现的强回波对郑州天气的影响进行了对比,得出了对郑州强对流天气临近预报有意义的参考结论。With the echo data of Zhengzhou 714CD Doppler radar trom May to August from 2002 to 2004, the severe convective echoes that move towards Zhengzhou within 90km （echo intensity≥50dBz, echo height≥9km） and produced near Zhengzhou are investigated. The relationship between thunderstorm outflow boundary and severe convective weather in Zhengzhou, and the impact of strong echoes without outflow boundary on weather of Zhengzhou are analyzed.
