摘　　要：通过对重点区域中国航天科工集团第六研究院附近地区大气电场的观测分析,重点分析有闪电发生时,雷暴天气过程大气电场及大气电场变化率的特征。通过对多个近距离雷暴活动的发生、发展及消散过程的分析,得出雷暴天气下的大气电场特征及变化规律;找出了针对航天六院附近地区的雷电预警的电场强度和变化率的雷电预警指标,用电场幅值阈值和差分阈值两种方法并结合闪电定位资料建立了预警模型为内蒙古地区针对重点区域有针对性的开展雷电预警预报工作打下基础。By the observation of atmospheric electric field in the of the key area sixth research institute of China aerospace science and industry corporation （hereinafter referred to as aerospace six yuan） and vicinity, it selective analysizes the change features of atmospheric electric field intensity and atmospheric electric field gradient in the process of lightning and thunderstorm. The characteristics and changes of atmospheric electric field in thunderstorm are obtained through the analysis of the occurrence, development and dissipation of multiple near-distance thunderstorms. Lightning warning index of atmospheric electric field intensity and atmospheric electric field gradient that aims at aerospace six yuan and vicinity is found out also. According to the key area in Inner Mongolia region, it established the early warning model, combining the method of electric field threshold value, difference threshold and lightning location data to lay the foundation for carrying out lightning warning and forecasting.
