VLF/LF高精度三维闪电定位系统的建立与应用

VLF/LF High Precision 3D Lightning Positioning System Establishment and Application

摘要: 为了加强对乌鲁木齐机场雷暴天气的监测和预警，VLF/LF高精度三维闪电定位系统分别布设在乌鲁木齐机场雷达站、阿什里、柴窝铺、呼图壁和阜康五个测站，这样就可以重点保证对发生在该区域内的闪电位置等关键信号进行实时捕捉。本文介绍了该闪电定位系统的探测原理和方法、系统功能，然后结合实际运行情况，选取了一次雷暴天气过程中闪电定位仪探测的闪电活动分析。分析结果表明三维雷电探测系统的定位精度和探测效率较好，弥补了机场多普勒天气雷达对强对流天气过程的实时监控和预警的不足。

Abstract: In order to strengthen the monitoring and early warning of thunderstorm weather in Urumqi Airport, the VLF/LF high-precision three-dimensional lightning positioning system, with the central station in Urumqi Airport radar station, and the other four stations in Ashli, Chaiwopu, Hutubi and Fukang, can focus on ensuring the real-time capture of lightning location and other key signals in this area. This paper introduces the detection principle, method and system function of the lightning positioning system, and then analyzes the lightning activity detected by the lightning locator in the course of a thunderstorm. The analysis results show that the positioning accuracy and detection efficiency of the three-dimensional lightning detection system are good, which makes up the deficiency of the real-time monitoring and early warning of the severe convection weather process of the airport Doppler weather radar.
