摘　　要：利用活动目录拓扑图(ADTD)闪电定位数据,结合地形高程数据统计分析中国南方地区的闪电时空分布特征,重点分析地形差异下的闪电活动特征、峰值变化及其季节性变化。统计分析发现,中国南方地区闪电夏多冬少,季节交替对闪电峰值时刻影响较小,主要分布在14时(北京时,BJT)至16时附近。中国南方地区地形高程变化较大处附近闪电峰值时刻会出现在0时左右,可见地形对闪电活动数量亦有影响。Using active divectory topology diagrammer(ADTD)lightning location data and terrain elevation data,the temporal and spatial distribution characteristics is analyzed of lightning in southern China,focusing on the characteristics of lightning activity,peak changes and seasonal changes under terrain differences.The statistical analysis shows that the lightning in southern China is more in summer than in winter,and the seasonal alternation has little influence on the lightning peak time,which is mainly distributed around 14:00(Beijing Time,BJT)to 16:00.The lightning peak time near the place where the terrain elevation changes greatly in southern China will occur around 0:00,which shows that the terrain also has an impact on the number of lightning activities.
