Abstract:
Electrified lightning and non-lightning producing clouds of various types are thought to play a major role in supplying current to the global electric circuit (GEC). Previous studies suggest that oceanic storms produce higher conduction currents than their continental counterparts. This study looks in depth at the variability of conduction currents and differences of other electrical and storm microphysical properties for oceanic and continental cloud types using electric field mill measurements above clouds, lightning, passive microwave and radar measurements.
