WebbFirst, thunderstorms and lightning are part of the Earth’s global electric circuit. Thunderstorms and electrified clouds are like batteries that cause the Earth to have negative charge and the atmosphere to have positive charge.. This maintains the fair weather electric field, which is about 100 V/m near the surface. arim name meaningThe dataset used in the ML model consists of data used as predictors, namely available meteorological data (air pressure, air temperature, relative humidity, and wind speed) and lightning activity data as the response.
