Beijing Lightning NETwork (BLNET): Configuration and Preliminary Results of Lightning Location

  • 摘要: 北京闪电综合探测网(Beijing Lightning NETwork, 简称BLNET)由10个观测站组成, 每个子站主要由闪电快、慢电场变化测量仪(也称快、慢天线)和闪电甚高频(VHF)辐射探测仪构成, 实现了对闪电的多频段的综合观测。本文首先详细介绍了BLNET的网络构成, 然后利用蒙特卡罗法对网络的定位误差进行了理论分析, 模拟结果表明网络内部水平定位误差小于200 m, 网络外部100 km处水平定位误差小于3 km, 最后利用Chan氏算法和Levenberg-Marquardt算法相结合的方法, 对发生在2013年7月7日的一次雷暴过程分别进行了地闪和云闪定位, 将定位结果和对应时次的雷达回波进行比较, 发现地闪和云闪都出现在大于30 dBZ的雷达回波区, 表明了探测网络和定位方法的可靠性。
