Abstract

Lightning location records were comprehensively compared with the high-resolution observation of triggered lightning and natural lightning in Guangzhou, to evaluate the performance characteristics of the Lightning Location System of Guangdong-Hongkong-Macau. The results show that the flash detection efficiency and stroke detection efficiency were about 74% and 40% respectively during 2007-2011, while 97% and 90% respectively in 2012. The arithmetic mean value and median value for location error was estimated to be about 2660 m and 1500 m during 2007-2011, while 950 m and 470 m respectively in 2012. Lightning Location System reported peak currents of triggered lightning records were about 30% lower than the truth during 20082012, while 300% higher in 2012. When the number of detection sub-station was significantly increased in 2012, the detection efficiency and location precision were found to be obviously improved, but the peak currents of return strokes were systematically overestimated.
