摘要
2011年6月23日故宫博物院锡庆门、箭亭等5个场所遭雷击.利用该日常规天气资料、卫星资料、雷达资料、大气电场资料、闪电定位资料,分析了该次雷击事件的天气背景和雷击时段大气电场、闪电分布的相关特征;根据雷击现场调查,分析了故宫遭雷击的具体原因和防雷薄弱环节,针对存在的问题给出了整改建议;提出了采取小范围雷电监测预警措施,进行故宫精细化雷电监测预警,改善故宫防雷现状.相关结论可以为文物古建场所的雷电监测预警以及防雷措施的选择提供参考.
On June 23,2011,five sites including Xiqing Gate and the Arrow Station in the Palace Museum were struck by lightning.The weather condition and the characteristics of atmospheric electric field and lightning distribu-tion during the lightning stroke period are analyzed in detail utilizing the routine weather data,satellite data,radar echo data,the atmospheric electric field data as well as the lightning data.Then,on the basis of the field investiga-tion of lightning stroke in each place,the specific causes of lightning stroke and the weak link of lightning protection are analyzed.Aiming at these existent problems,the improvement suggestions are given. Especially,the small scale lightning monitoring and early warning measures are put forward.Thus the precise monitoring and warning measures will be implemented and the lightning protection of the Palace Museum will be improved.Some references are pro-vided for lightning monitoring ＆amp; warning and the selection of lightning protection measures in the cultural relics sites.
