Abstract:
Based on the Lightning data obtained from the lightning location system in Hubei Province from 2007 to 2016, the evaluation model of lightning intensity is established after the statistical analysis of the characteristics of lightning current amplitude and lightning steepness. The lightning intensity is divided into four levels: weak (I), medium (II), strong (III) and extremely strong (IV) by using the method of symmetrical unequal interval, and the thresholds for each level are calculated. In addition to test the rationality of the classification threshold, a further inspection is also made with the thunder and lightning disaster data. The results show that the lightning intensity classification method is objective and feasible, which can provide references for lightning disaster assessment and classification, and lightning warning and forecasting.
