| 摘 要： | 利用地闪定位仪（ＤＦ）探测了我国大兴安岭（东北地区）和北京地区的雷电活动。文中详细分析了地闪的空间分布,并讨论了不同地区各雷电参量的时间变化规律。两地区雷电活动的季节变化与日变化均有较大差异。这些差异的产生可能与本地区的天气背景及地理特征有密切的联系。要较深入地了解上述差异产生的可能原因,将雷电活动与天气因子的给合讨论是必需的。

| Abstract: | Based on the cloud to ground lightning flash data obtained by direction finder(DF) in Beijing area and North of China, the lightning spatial distributions and the regularities of all lightning factors are discussed respectively for negative and positive lightning in this paper. The results indicate that there are great difference in seasonal and diurnal variation between two type flashes. This gap maybe caused by the different weather patterns and geography features. It is necessary that we should pay more attention to correlations between the weather factors and the lightning activities in order to obtain the realistic reason which lead difference of lightning distributions in different regions. |
