The characteristics of lightning monitoring and positioning system in Inner Mongolia were introduced and studied in the lightning accident analysis based on the lightning monitoring and positioning data of the lightning stroke accidents. The positioning error of lightning monitoring and positioning system was analyzed. The results showed that lightning current intensity and the position precision were very important data in the lightning disaster investigation. Finally, a variety of meteorological data should be applied in the lightning disaster investigation and identification.展开更多

The results show that the effective detection radius of a lightning monitoring sub-station in Guizhou Province is 160 km; some counties in the southwest,northwest and northeast of Guizhou were not detected. To improve the detector efficiency of lightning monitoring network in Guizhou Province,it is suggested that nine sub-stations should be built in Weining,Shuicheng,Qinglong,Pingtang,Rongjiang,Yuping,Songtao,Tongren and Renhuai,so that the effective detection efficiency will reach more than 95%.展开更多

For the weather monitoring station, it not only realizes the automatic detection, but also makes the weather monitoring station have a larger space for growth. At the same time, the staff of the weather monitoring station needs to focus on how to reduce the lightning strike rate and then make the correctness of the weather monitoring improve. In view of this, this paper mainly discusses the disadvantages of lightning protection in meteorological monitoring field and the corresponding treatment strategies for reference only.展开更多
