摘　　要：为了找出雷暴活动过程中地面大气电场的特征,利用泰山和西双版纳两地积累的大气电场资料,讨论了雷暴过程中大气电场正负跳变的形成原因。通过对大气电场资料的统计分析,给出了雷暴活动期间大气电场的均值分布情况及大气电场的波动范围。并对比分析了泰山和西双版纳两地雷暴活动过程中大气电场变化的共同点及不同之处。分析了两地的雷暴时段分布特征,给出了雷暴在一天当中活动的时段分布情况,并讨论了形成这种分布的原因。对两地雷暴电场特征的分析揭示了两地雷暴过程的时段分布、强度变化及闪电发生时间间隔等规律,可为雷电预警预报工作提供指导。In order to find out the characteristics of atmospheric electric field during thunderstorm, the collected atmospheric electric field data in both Mountain Taishan and in Xishuangbanna was used in the study. The causation of leap in atmospheric electric field curve during thunderstorm was discussed. Statistics showed the mean and fluctuation range of atmospheric electric field during thunderstorm, and contrastive analysis gave out the common ground and differentia of electric field changes in Mountain Taishan and Xishuanghanna. Thunderstorm climate characteristics of the two places were analyzed, and the study gave out the period of time distributing of thunderstorm during 24 hours and the cause of this distributing was debated later. The characteristics of thunderstorm electric field on Mountain Taishan and in Xishuangbanna show the thunderstorm＇s distributing period of time, intensity change, and the time interval of lightning, which can offer guidance for thunderstorm and lightning forecasting and warning.
