摘　　要：我们利用布设的地面大气电场仪观测沙尘天气中大气电场的变化。通过对2002年春季几次沙尘天气过程中大气电场数据的分析,获得了沙尘暴、扬沙、浮尘等天气现象初步的大气电场特征。通过比较沙尘和雷暴天气现象下的大气电场特征,我们认为可以将大气电场仪作为有效的监测装备用于监测沙尘天气现象,而应用于气象业务。The variance of atmospheric electric field was recorded with a surface-based electric field mill instrument during several sand/dust events in the spring of 2002.By Analyses on the data, the primary features of the electric fields of sandstorm, flowing sand and floating dust were obtained. The electric field features in sand storm and in thunderstorm were compared.The studies provided a possibility of applying this method to moniter the sandstorm.
