Title: A Research on the Characteristics of Lightning in Hailstorms of Beijing Area by the Method of Analysis the Lightning Detection Data and Numerical Simulation
Abstract: In this paper, by using lightning detection material of Beijing area, we analyzing the characteristics of lightning in four hailstorms. The results show that the mean percentage of cloud-to-ground (CG) lightning accounting for the total lightning is 8.28%, which is lower than the normal thunderstorms. On the contrary, the CG lightning has a higher proportion of positive CG than the normal thunderstorms. All cases variation trend of lightning frequency show a conspicuous intensive increase before the hail reaches the ground. The peak lightning frequency usually occurs 5 to 80min earlier than hailstone falling. These characteristics may have contribution to the forecasting of hailstorms of Beijing area. Another work was done by using a two-dimensional numerical model which includes dynamic, microphysics, electrification and discharge to simulate these four instances. The results present similar characteristics with the actual detection data. This will lay a foundation for the continuing studies of the relationship between hailstorm and lightning and the inherent reason of the relationship by using the method of numerical simulation.
