摘　　要：根据南昌CINRADWSR 98D天气雷达获取的 2 0 0 2年 4月 5日的平均径向速度场和强度场回波资料 ,结合当日探空、5 0 0hPa及地面天气形势等资料分析发现 :2 0 0 2年 4月 5日的强风夹带飑线天气过程的发生、发展 ,在高空、地面天气形势及层结稳定度方面均表现出明显特征 。Based on the velocity and intensity field data from CINRAD WSR 98D weather radar, an analysis was made of the squall lines on 5 April 2002 in conjunction with the radiosonde data and 500 hPa and surface weather data at the same day. Results indicate that there were obvious characteristics in the surface and upper level weather patterns and in stratification stability, as well as in Doppler radar echoes during the formation and development periods of the squall lines.
