Temporal and Spatial Characteristics of Lightning Activity in Huai''''an during 2011 -2014

摘要

Based on the monitoring data of lightning activity in Huai''''an from 2011 to 2014, the temporal and spatial distribution of lightning activity and lightning density were analyzed. The results show that positive and negative lightning activity in Huai9an had obvious seasonal variations and diurnal variations during 2011 -2014. The month changes of positive and negative lightning activity had a single peak and valley, while the diurnal variations of both positive and negative lightning activity had double peaks and valleys. The high-value areas of ground flash density in Huai9an had obvious randomness. Seen from the spatial distribution of annual average of ground flash density, lightning activity was mainly distributed in Xuyi County, Jinhu County and Huai''''an District.
