| 摘 要： | 利用一次包含8次回击过程的人工触发闪电事件的近距离光电观测数据,分析了广东省气象闪电定位系统对其回击过程的定位结果。结果表明,回击过程探测效率约为75%(6/8),回击平均定位误差约为3768m。为了分析定位误差来源,通过对比分析的方法,逐次引入各探测子站原始记录重新进行定位计算,发现剔除误差较大的探测子站后,平均定位误差为2192m,比原来降低42%。

| Abstract: | The Lightning Location System (LLS) records of Guangdong meteorological department was analyzed comprehensively based on the close Optical-Electrical observation of one rocket-triggered lightning which contains 8 return strokes.The results show that the stroke detection efficiency was about 75%(6/8),and the average spatial location error was about 3 768 meters.For determination of the location error source,computation was re-executed based on the step-by-step introduction of the primary records of sub-stati... |
