- 摘要:
- 利用在山东滨州沾化区人工引雷实验得到的2017-2020年30次闪电数据,对比分析ADTD闪电定位系统在人工引雷场地及其相似地区的定位效率、定位精度及电流峰值偏差。结果表明ADTD对人工引雷触发闪电事件定位效率为60%(即18/30),回击闪电定位效率为88.89%(即8/9),回击过程定位效率34.48%(10/29),ICC闪电定位效率47.62%(10/21)。定位精度31.724 km,负地闪定位精度高于正地闪,2站以上定位精度高于2站定位。电流峰值偏差36.38%。
- Abstract:
- Using the 30 lightning data from 2017 to 2020 obtained from the rocket-triggered lightning test in Binzhou Zhanhua District of Shandong Province,the positioning efficiency,positioning accuracy,and current peak deviation of the ADTD lightning location system in the Rocket-Triggered place and similar areas are compared,and analyzed. The results show that ADTD has a positioning efficiency of lighting events is 60%(18/30). The lightning location efficiency with return stroke is 88.89%(8/9).Positioning efficiency of lightning return is 34.48%(10/29). Continuous current positioning efficiency is 47.62%(10/21). Positioning accuracy is 31.724 km. The positioning accuracy of negative cloud-to-ground lightning is higher than that of positive cloud-to-ground lightning.The positioning accuracy of more than 2 stations is higher than that of 2 stations. Peak current deviation is 36.38%.
