摘要:
利用广西2016-2019年VLF/LF和ADTD两套闪电定位系统的地闪资料进行对比分析，并利用典型雷灾事故数据进行评估。结果表明，两套系统的监测结果均以负地闪为主，VLF/LF探测效率约是ADTD的2．6倍，尤其是正地闪以及弱地闪探测效率明显提高，VLF/LF地闪平均雷电流幅值较ADTD偏小且两者差异较大；在地闪频次及雷电流幅值的年变化和日变化上，两套系统的监测结果较为一致，月变化差异较大；在空间分布上，两套系统的地闪密度分布较为一致，雷电流幅值分布差异较大；雷灾事故评估表明VLF/LF定位的准确性和可靠性优于ADTD。
Abstract:
The ground flash data of the two sets of lightning positioning systems VLF/LF and ADTD in Guangxi from 2016 to 2019 were used for comparative analysis, and the typical lightning disaster accident data was used for evaluation. The monitoring results of the two systems were mainly negative ground flash, and the detection efficiency of VLF/LF was about 2.6 times that of ADTD, especially the detection efficiency of positive ground flash and weak ground flash was significantly improved. The average lightning current amplitude of VLF/LF was smaller than ADTD, and the difference between them was larger. In terms of annual and daily changes of lightning frequency and lightning current amplitude, the monitoring results of the two systems were relatively consistent, while the monthly changes were quite different; in terms of spatial distribution, the lightning density distribution of the two systems was relatively consistent, and the lightning current amplitude distribution was different. The assessment of lightning disaster accidents showed that the accuracy and reliability of VLF/LF positioning was better than ADTD.
