AB: Hurricane eyewall lightning is seldom observed during the development and quiescent periods of a hurricane's lifetime. However, observational evidence collected during the 2004 and 2005 hurricane seasons suggests that abundant eyewall lightning is present during periods of rapid intensification. We provide a conceptual model of hurricane electrification during the rapid intensification phase, and analyze the current and historical Atlantic hurricane records to determine frequency and strength of rapid intensification. We correlate hurricane intensification with eyewall lightning frequency using the National Lightning Detection Network (NLDN) and Los Alamos Sferic Array (LASA) lightning databases to assess the potential efficacy of remote eyewall lightning observations for hurricane intensity monitoring.
