Analysis of Ground Lightning Characteristics in Handan
摘要
Abstract
Based on the monitoring data of lightning from 2005 - 2008 in Handan, the law and characteristics of lightning were analyzed. Result showed that, negative ground lightning was the dominant one in ground lightning. Ground lightning and negative ground lightning were in unimod-al distribution from February to November, both reached the peak in July and in August, which was corresponding to the period when convective activity and precipitation occurred most frequently. The diurnal variation curve of ground lightning was in four-peak distribution, which reached the peak at 15:00 and 19:00. Otherwise, the diurnal variation of ground lightning was consistent to the law of diurnal variation when severe convective weather happened, positive ground lightning occurred behind negative ground lightning The diurnal variation corresponding to the ratio between positive ground lightning and total ground lightning indicated that severe convective weather generally grew intensely after 16:00, and the time when convective weather grew mature in one day from 17:00 to 19:00. The mid-west areas were the areas where lightning with high density took place the most frequently and showed significant characteristics.关键词
