| Abstract: | Using the synchronous data of the lightning monitoring and warning network,Doppler radar,and regional AWS precipitation from a severe storm occurred in Qinhuangdao on 6 July 2009,a detailed analysis is carried out.The results show that the lightning process was dominated by negative ground flashes,with the maximum of lightning frequency being 712 times per hour;the lightning discharge trajectory was northwest-southeast oriented,moving from north to south,with the hourly rainfall being more than 100 mm per h... |
| Keywords: | disaster-inducing lightning radar echo AWS precipitation lightning frequency |
