title: Thunderstorm Electrification and Raindrop Collisions and Disjection in an Electric Field.
abstract: Raindrop collisions in an electric field selectively transfer charges of one sign to the larger disjected drops. The disjected drops, falling away from the smaller drops, separate free charge to establish electric fields as large as those observed in thunderstorms.
