| 摘 要： | 1985年夏季我们在东乡地区进行了雷暴和闪电的雷达及电学特征的综合观测研究。观测点在兰州西南方向60km,海拔2408m,地处青藏高原边缘。观测设备除一3cm气象雷达外还有平均电场仪、电场变化仪,超高频场强计等电学测量仪器。资料初步分析表明,闪电进行过程中一般伴随有VHF电

| Abstract: | This paper describes the preliminary results of observation to the thunderstorm and lightning in Dongxiang,Gansu with apparatus such as weather radar,field mill electric change meter and VHF field-strenrah meter.Data analysis shows that there are often strong VHF radiations during lightning discharge process.A layer of positive charge often exists in the lower region of thunderstorms and most of cloud flashes take place between this layer and negafive charge region above. |
