摘要
主要选取1998—2017年杭州雷电观测资料,对雷电灾害特征进行分析,并提出了相关的安全防御对策。结果表明,杭州市近20年来雷电灾害总体呈显著增加的变化趋势,气候倾向率为84.444次/10年;杭州市雷电灾害在3—9月出现比较频繁,8月雷电灾害次数最多,12月和1月最少;杭州市夏季雷电次数出现最为频繁,春季次之,秋季较少,冬季最少。面对杭州雷电灾害多发的严峻形势,防雷技术人员应加强雷电监测、预警预报工作,科学指导群众采取雷电安全防御措施,定期开展防雷装置安全检测工作,从而有效防御雷电灾害,保障人民生命财产以及社会公共安全。
Based on the lightning observation data of Hangzhou from 1998 to 2017,the characteristics of lightning disasters were analyzed,and the relevant security countermeasures were put forward.The results showed that lightning disasters in Hangzhou had increased significantly in the past 20 years.The climatic tendency was 84.444 times per 10 years.The lightning disasters occurred frequently in March-September in Hangzhou,with the largest number of lightning disasters in August and the least in December and January.Hangzhou had the most frequent lightning frequency in summer,followed by spring,fewer in autumn and the least in winter.Faced with the severe situation of frequent lightning disasters in Hangzhou,lightning protection technicians should strengthen lightning monitoring,early warning and forecasting work,scientifically guide the masses to take lightning safety defense measures,and regularly carry out the safety detection of lightning protection devices,so as to effectively prevent lightning disasters,protect people’s lives and property and social public safety.
