“…No corrections for detection efficiency have been made to the data presented in this paper. Systematic •ngle errors also exist in direction finding networks and these have been extensively studied by Machet al (1986) and Schutte et al (1987). Since the summer of 1985, we have applied site error corrections and calculated the optimal lightning location in real time .…”

A bipole pattern has been observed in the locations of lightning flashes that lower positive and negative charge to earth in mesoscale storm systems. The pattern has a characteristic size of about 100 km and may last for many hours. The pattern is aligned with the upper level winds and has been observed in all seasons, but is more apparent in the fall and winter. The ratio of the positive flash density to the negative flash density is approximately 0.1, but varies from 0.05 to 0.2. This ratio occurs because there are fewer positive flashes and they are more spatially dispersed than negative flashes in storm systems.

“…The layout of an LDN plays a crucial role in determining the spatial distribution of lightning location accuracy. Prior studies predominantly emphasized the location accuracy distribution of LDNs with varying geometric configurations, typically deployed over flat terrains [27,31]. No studies have delved into the impact of LDNs featuring a consistent vertical layout on location accuracy.…”

This study investigates the location accuracy distribution of the lightning detection networks (LDNs) deployed on inclined terrains, an aspect frequently encountered in complex terrains but hitherto disregarded in previous studies. By designing eight substation LDNs deployed on slope-type (ST), mountain-type (MT) and basin-type (BT) terrains, respectively, we employed Monte Carlo simulations to analyze their spatial location accuracy distribution based on time-of-arrival technology. Significant differences among the LDNs on inclined terrains and between them and the LDN on plain-type (PT) terrain were revealed. Compared to the PT LDN, LDNs on inclined terrains exhibited a reduction in high-precision location regions and a shift in the distribution pattern of location accuracy. The ST LDN showed marked deviations in the high-precision vertical location toward the lower slope side with increases in the elevation angle and consistently smaller high-precision vertical location areas compared to MT and BT LDNs. The variations in elevation angles of MT and BT LDNs had a substantial impact on the spatial distribution patterns of both horizontal and vertical location accuracy, with BT LDNs featuring larger vertical high-precision areas than MT LDNs. Our conclusions were further corroborated through an analysis of an actual LDN, which combined characteristics from both ST and MT terrain patterns.
