| 摘 要： | 选取了青藏高原东北侧临夏站1980—2010年的雷暴观测资料和陇中地区闪电定位仪2006—2010年的闪电观测资料,利用统计学手段对该地区雷电的年际变化、年变化、日变化、首次发生雷暴方向、地闪密度等进行了分析.基本揭示了该地区雷电的发生特征,发现一年中雷电主要发生在夏季,一天中雷电主要发生在下午及傍晚,地闪密度高于中国平均密度.对该地区雷电灾害防灾减灾工作有一定的促进意义.

| Abstract: | By using the thunderstorm observation data from 1980 to 2010 of Linxia station in the northeast side of Qinghai-Tibet Plateau and the lightning data from 2006 to 2010 in the middle area of Gansu,thunderstorm and lightning characteristics such as inter-annual variation,annual variation,diurnal variation,directions of first thunderstorm,cloud-to-ground lightning density,etc were analyzed.The results of this paper found the formation characteristics of thunderstorm and lightning:the thunderstorms and lightning mainly happened in the summer and afternoon;the cloud-to-ground lightning density is higher than the average densities in China.This research will be useful to prevention and mitigation of disasters. |
