摘要
为探究闪电与多尺度气象要素的关系,该文利用闪电定位资料、多普勒雷达资料、天气图以及自动气象站资料对2016年3月8日平远双溪雷击事故进行了分析。结果表明:"16.03.08"平远双溪雷击事故是1次局地对流小系统,该区域K值很低,正的SI,天气比较稳定,无明显不稳定能量,地面表现为脊后槽前型,700 hPa为槽前型;事故发生地雷达回波强度为45~50 dBZ,是1次正地闪。同时还进一步分析了此次雷击事故带来的一些思考,以期对未来雷电预警预报服务有所借鉴。
To explore the relation between lightning and multi-scale meteorological elements, the lightning location data and Doppler radar data, weather map and data from automatic weather station of March 8, 2016 Shuangxi lightning accident in Piugyuau are analyzed. The results show that 2016. 03.08 is a ligbtning accident of local convective system in Shuangxi. The K value is very low, and the SI is Positive. The weather is relatively stable without obvious unstable energy, and ground symptom is posterior groove type, which 700hPa type is front trough pattern; the radar echo intensity is 45 -50dbz, is a positive cg. Some thoughts on the lightning accident are analyzed in further, which hope to play an indicative role of future lightning warming forecast.
