Lightning Data Observed With Lightning Location System in Guang-Dong Province, China

Abstract

This paper presents an investigation into cloud-to-ground lightning activity data collected by a lightning detection system in the Guang-Dong Province, the southernmost in China. Annual lightning days are acquired and ground flash density maps are constructed from the database, which contains the information of more than one million flashes. The lightning days are compared with annual thunderstorm days collected by the Guang-Dong Meteorological Agency, and a weak correlation is noted. The correlation between ground flash density and thunderstorm day is studied, and an empirical formula is presented. The relationship between transmission line faults and ground flash density is discussed in this paper too. It is noted that the correlation with the faults caused by lightning is relatively high. The correlation coefficient does not significantly vary with the threshold of discharge current set for constructing the map of revised ground flash density.

Terrestrial gamma ray flashes due to particle acceleration in tropical storm systems

“…However, they also found that weaker hurricanes generated more lightning flashes within the inner core region and additionally observed that there was a strong correlation between lightning activity within this region and the minimum sea level pressure for 12 of the 16 hurricanes in the sample. Zhang et al [] performed a similar study for tropical storms in the northwest Pacific Ocean using the Guandong Lightning Location System [ Chen et al , ]. In this study, radial distribution of lightning was found to be dependent on the intensity of the storm system.…”

Physical and observable characteristics of cloud‐to‐ground lightning over the Pearl River Delta region of South China

“…Lightning characteristics had been studied in Beijing, Tibet Plateau, and Guangdong [Chen et al, 2004;Qie et al, 1991Qie et al, , 2002. Both natural lightning and artificial-triggered lightning had been used to study the physical processes of lightning and electric charge structure of thunderstorm [Lü et al, 2012;Qie et al, 2006Qie et al, , 2009Zhang et al, 2014].…”

Lightning occurrence characteristics in Japan for 17 years: observation results with lightning location systems of electric power utilities from 1992 to 2008

“…Cloud‐to‐ground lightning flash frequency is one of the important factors for the rational insulation design of power transmission systems. Recently, lightning location systems (LLSs) have been widely used and lightning data with such systems have been collected and summarized all over the world [1–6]. In Japan, nine electric power companies have their own LLSs, and the lightning data have been collected.…”
