摘要
根据衡水市2009—2020年闪电定位数据和1972—2013年雷暴日资料,采用Kriging插值和统计分析方法,对衡水湖景区的雷电活动时空分布特征进行分析。结果表明,衡水湖景区雷暴日数总体呈轻微减小趋势,历年最大为37 d,最小为15 d;雷电活动时间分布特征明显,8月最频繁,占全年的61.6%,18:00—20:00和次日3:00—4:00为雷电多发时段;空间上地闪密度呈北高南低分布,旅游码头区域最高,为2.8次/(km^(2)·a)左右,闾里古镇区域最低,为1.4次/(km^(2)·a)左右;雷电流强度呈外高内低分布,衡水园博园、旅游码头和湖中岛3个区域平均雷电流为32 kA左右,衡水湖南部为26 kA左右,闾里古镇为18 kA左右。结合景区实际,提出了“五位一体”防雷减灾策略,以期有助于提高景区防雷减灾水平,有效保障游客生命财产安全。
Based on lightning location data during 2009—2020 and the data of thunderstorm days during 1972—2013 in Hengshui City,Kriging interpolation and statistical analysis methods were used to analyze the temporal and spatial distribution characteristics of lightning activity in Hengshui Lake scenic spot.The results showed that the number of thunderstorm days in Hengshui Lake scenic area showed a slight decreasing trend,with the maximum of 37 days and the minimum of 15 days;the temporal distribution characteristics was obvious,and it was most frequent in August,accounting for 61.6%of the whole year,and the peak periods of daily lightning activity were 18:00—20:00 and 3:00—4:00;the spatial distribution of ground lightning density was high in the north and low in the south.The Tourism Wharf had the highest rate of about 2.8 times/(km^(2)·a),while the Lyuli Ancient Town had the lowest rate of about1.4 times/(km^(2)·a);the spatial distribution of ground lightning current density was high outside and low inside.The average lightning current of Hengshui Garden Expo Park,Tourism Wharf and Island was about 32 kA,and Southern of Hengshui Lake was about 26kA,and Lyuli Ancient Town was about 18 kA.Combining with the reality of the scenic spot,the“five-in-one”lightning protection and disaster reduction strategy was put forward to help improve the level of lightning protection and disaster reduction in the scenic spot and effectively protect the safety of tourists’life and property.
