Clustering Phenomena in the Time Distribution of Lightning
Abstract
Two years of lightning data, measured during 2002 and 2003 in two areas of Italy, Lombardia (northern Italy) and Campania (southern Italy), have been investigated in order to reveal clustering properties in their time dynamics. The Allan Factor analysis has been performed. Our findings point out to the existence of time-clustering in the sequence of lightning time-occurrences, characterized by the presence of two scaling regions, which reveal intra-cluster (inside individual thunderstorms) and inter-cluster (among successive thunderstorms) time-clustering properties of lightning data. A crossover timescale is identified, which could be connected with the mean duration of a thunderstorm.
