大气电场大气电场atmosphericelectricfield大气中存在的电场。地面带着负电，大气中含有净的正电荷，所以大气中时刻存在电场。大气电场的方向指向地面，强度随时间、地点、天气状况和离地面的高度而变。按天气状况可分为晴天电场和扰动天气电场。晴天电场是指晴天条件下的大气电场，电场方向铅直朝下，就全球平均而言，晴天电场强度在陆地上为120伏／米，在海洋上为130伏／米。在工业区由于空气中存在高浓度的气溶胶，电场强度会增至每米数百伏。晴天电场随纬度而增大，称为纬度效应。晴天电场具有日变化和年变化，在海洋和两极地区，电场日变化和地方时无关，在世界时19时左右出现极大，04时左右出现极小，振幅约达平均值的20％。对陆地测站而言，日变化和地方时有关，在地方时04～06时和12～16时出现极小值，07～10时和19～21时出现极大值，振幅约达平均值的50％。电场的年变化在海洋上不明显，陆地上测得冬季出现极大值，夏季出现极小值。扰动天气电场是指存在着激烈的天气现象（如雷暴、雪暴、尘暴）时的大气电场。其特点是电场方向和数值上均有明显的不规则变化。如雷雨云下的电场可达－104伏／米，其中负号表示电场方向向上。在层状云和积状云中，电场的大小和方向变化很大，通常出现的场强约为每米数百伏。雷雨云中则可达104～105伏／米。
