摘要
文章利用2007—2020年宁夏闪电定位监测数据,分析了雷电流强度绝对值10 kA以下小幅值、200 kA和300 kA以上大幅值地闪次数分布,提出剔除雷电流强度在6 kA以下和300 kA以上地闪数据作为数据质量控制方法;对比分析了质量控制前后雷电流强度统计特征变化;分析了2007—2020年宁夏地闪年度、季节、月度、日和24 h分布特征,为宁夏防雷减灾研究和工作提供参考。
Based on the monitoring data from 2007 to 2020 in Ningxia,the distribution of small value below 10 kA and large value above 200 kA and 300 kA of lightning current intensity was analyzed,and the data quality control method was proposed to eliminate the lightning current intensity below 6 kA and above 300 kA.The statistical characteristics of lightning current intensity before and after quality control were compared and analyzed.The annual,seasonal,monthly,daily and 24-hour distribution characteristics of lightning in Ningxia from 2007 to 2020 were analyzed,providing reference for the study of lightning prevention and disaster reduction in Ningxia.
