摘要
基于杭州的地理位置及气象历史数据,分析了2022年第19届亚运会举办城市杭州的雷暴气候变化规律和闪电的时空分布特征、赛事核心区内雷电时空分布特征以及2007~2020年雷电流强度与雷电流幅值概率分布,定量表征了该区域雷电活动的强弱。根据赛会核心区内雷电流幅值年最大值的平均值,计算了雷击点与屏蔽空间距离不同时,场馆处无衰减的磁场强度值,为场馆雷电防护及内部电子信息系统设计提供依据和参考。
Based on the geographical location and meteorological historical data of Hangzhou,the climate change laws of thunderstorms and the spatiotemporal distribution characteristics of lightning in Hangzhou,the host city of the 19th Asian Games in 2022,the spatiotemporal distribution characteristics of lightning in the core area of the event,and the lightning current intensity and lightning current amplitude probability distribution from 2007 to 2020 were analyzed.The intensity of lightning activity in this area was quantitatively characterized.According to the average value of the annual maximum value of the lightning current amplitude in the core area of the competition,when the distance between the lightning strike point and the shielding space is different,the non-attenuated magnetic field strength value at the stadium is calculated,which provides a basis and reference for the design of lightning protection and internal electronic information system of the stadium.
