摘　　要：近地面大气电场仪一般采用电场阈值法进行雷电预警,实际业务应用中容易出现空报和漏报,而结合差分电场可以有效提高预报准确率。本文利用大气电场仪分析民航气象保障工作中关注的初雷、强雷暴、干雷暴、阵雨等4种强对流天气下大气电场和差分电场的变化特征,分析结果表明不同强对流天气背景下的大气电场和差分电场有着显著差异,利用其特征能够在机场预报中提高强对流天气类型判别和预警预报能力。At present the research of ground atmospheric electric field is mainly used to provide lightning warning. But it may produce false weather messages. Combining with the method of electric field temporal difference, the broadcast accuracy can be greatly improved. This paper analyzes the characteristics of initial thunderstorms, severe thunderstorms, dry thunderstorms, rain without thun- derstorm which are highly concerned by civil aviation meteorological personnel. Results show that under different atmospheric convective weather conditions, atmospheric electric field and electric field temporal difference have significant variation which can improve convective weather forecasting and warning accuracy.
