| 摘 要： | ;利用闪电定位资料和气象台站记录的雷暴日资料,对揭阳市闪电密度地理特征进行了分析.研究表明,揭阳市的雷暴频繁高发期主要集中在5～9月,7、8月份尤其显著;闪电密度较大的地区主要在普宁市洪阳地区、大砰地区、揭东县五房地区和揭西县大北山地区,揭阳市区主要在渔湖半岛和仙桥紫峰山区,惠来县闪电密度相对较小,不过雷电流强度较大;雷电流强度大部分在60KA以下.闪电的分布规律与当地环境有很大的关系.

| Abstract: | In terms of the observations from lightning location system and the number of thunderstorm day from Jieyang weather station,the spatial and temporal distribution characteristics of lighting density was analyzed.The result shows that(1) lightning occurrence has a peak period from May to September,July and August especially;(2) several areas with strong(weak) lightning activities are indicated.(3)the spatial and temporal distribution of lightning are mostly associated with the local environment. |
