摘要文章利用克拉玛依地区的大气电场仪组网资料、闪电定位系统资料和常规观测数据等,对克拉玛依地区2013年晴天大气电场和雷暴天气中的地面大气电场特征进行了分析,结果表明:44个晴天大气电场样本的平均场强日变化存在“双峰双谷”的特征,峰值出现在09:00和18:00左右,谷值出现在14:00和00:00左右,平均场强值的几何平均值在0.18~0.30 kV/m之间。设置了三级本地化的雷暴电场警报阈值,电场仪自动监测预警的雷暴事件与闪电定位仪监测资料较为一致,地面大气电场的演变可以较好的反映出地闪的活动信息。

Abstract：Based on the monitoring data from atmospheric electric field device,lightning location system and conventional meteorological observation in Karamay area,this paper analyzed the characteristics of electric field of fair-weather and thunderstorm weather days of Karamay City in 2013.The results show that the diurnal variation in the atmosphere electric field in 44 fair-weather days indicated double peak and double vally.The peak occurred at 9 and 18 oclock and the vally occurred at 14 and 00 oclock.And the geometric mean value of the electric field peak values is 0.18—0.30 kV/m.The local lightning warning threshold values for the three levels were set up.The thunderstorm weather event automatically monitored and forecasted by electric field device is nearly consistent with the monitoring data of lightning position indicator.The evolution of ground atmosphere electric field can better reflect the ground flash activity

Key words： arid area atmospheric electric field warning threshold
