摘　　要：利用云南省不同地理位置的13个闪电定位仪组成的闪电定位系统获得的2008年云地闪电资料对云南省雷暴的时空分布特征进行了初步分析,同时还利用同期云南省雷电灾害统计资料对云南省的雷电灾害特征进行分析。结果表明,云南省闪电密度高值区以中部地区为主,呈辐射状逐渐减少;就同纬度地区而言,雷电活动东部较西部频繁;全省雷电活动的月变化呈单峰单谷型,5—9月为雷暴活动的高发期。雷电灾害主要发生于4—9月,电力和通信行业受灾最为严重。Based on the cloud-to-ground lightning data in 2008,which was collected by the lightning location system composed of 13 lightning detectors,the spatial and temporal characteristics of thunderstorm in Yunnan Province were analyzed.Meanwhile,the characteristics of the lightning hazard were analyzed with lightning disaster statistics on the same period in Yunnan Province.The results showed that lightning density up to its maximum in the central part of Yunnan Province,was gradually reduced radiation.On the same latitude,thunderstorm activity was more frequent in the east than in the west.The diurnal variation of lightning activity in Yunnan Province showed a single peak-valley type and thunderstorm activity was most frequent from May to September.Lightning disaster occurred mainly from April to September,electricity and communications sectors were most severely affected.
