贵州省闪电定位资料中小幅值地闪范围研究

Study of the Small Amplitude Range of Cloud-to-ground Lightning Location Data in Guizhou Province

采用2006—2015年贵州省ADTD闪电定位资料，应用Matlab软件中的曲线拟合工具箱对数据进行对数正态分布拟合，利用非参数正态分布检验中的Kolmogorov—Smirnov检验方法（简称K？S检验方法）分析各区间拟合效果，最终确定贵州省闪电定位系统资料的“小幅值地闪”干扰区间为－10～2kA，该结论为贵州省闪电资料修正提供理论依据，在使用ADTD闪电定位资料时可先将此区间误差数据剔除。该研究为利用闪电定位资料确定雷电灾害风险区划提供重要参考。

Using the 2006—2015 ADTD lightning location data in Guizhou Province, fitting the data with the log normal distribution by using the curve fitting toolbox of Matlab software, using non-parametric normal distribution test of Kolmogorov-Smirnov test method （ K-S test） to analyze the interval fitting effect. The interference interval of the“small amplitude cloud-to？ground lighting” of lightning location system in Guizhou province ranges in -10 ~2kA. This conclusion provides theory basis for lightning data correction in Guizhou Province. The data in this error burst can be removed when using ADTD lightning location data. This study provides an important reference for determining the lightning disaster risk zoning based on lightning location data.
