Thunderstorms, lightning, and the Global Electric Circuit (GEC) are interconnected, and their studies have significant implications for understanding the global climate. Solar insolation plays a role in linking lightning distribution to Earth's climate. Extensive research on the GEC has aimed to establish a connection between variations in the fair-weather electric field (known as the Carnegie curve) and global variations in electrified weather, using lightning rates as a proxy.
Thunderstorm-induced muon events (TIMEs) are observed when strong electric fields in thunderstorms modulate muon acceleration, leading to changes in their count rate at the observational level. In this study, we report a substantial number of TIMEs observed
continuously over a fifteen-year period (2006-2020). Furthermore, we examine the diurnal distribution patterns of these events by comparing them with the Carnegie curve. The observed comparative pattern stimulates contemplation about the relationship between the GEC and TIMEs and suggests the former's potential role in the formation of the latter.
