江南夏季雷电的云回波特征分析

Feature analysis of cloud echo of thunder in Summer

根据南昌713雷达取获的2000年6～7月雷暴回波，结合地面闪电及雷电灾害实况， 对夏季雷电的云回波特征、天气形势及大气稳定度进行初步分析。结果表明，强雷电回波的 产生离不开高温、高湿的大气环境。另外，强雷电与强降水、雷雨大风、冰雹等强对流天气 一样，均出自强烈发展的雷暴中，但它们在天气形势和雷达回波参数上又有所区别。

：According to the data of thunderstorm echo in June－July,2000,which is get from 713 Radar in Nanchang,surface lighting and thunder disaster,analyse cloud echo feature of thunder,weather situation and atmospheric stability.The re sult shows that the emerge of intensive thunder echo needs the atmospheri enviro nment which temperature and humidity are high.Furthermore,intensive thunder is f rom the thunderstorm that develop intensively,which is same as other intensive c onvention weather,such as intensive precipitation,thunder gale and hail.But whic h weather situation and Radar echo parameter are different.
