Ice Particle Charge Transfer Studies.

Abstract

Electric charge transfer between ice crystals and an ice target has been measured under a range of environmental conditions in which simulate the environment of a thunderstorm. The charge transfer is very dependent on ice crystal size and cold chamber which permits long growth times has been used to determine charge/size relationships for crystal sizes up to 800 micrometers. Also, a new hot-wire device has been developed to measure liquid water content. The collection efficiencies of a rimed target for water droplets and ice crystals have been determined. High velocity crystal/target impacts up to 100 m/s show a maximum charge transfer at 25 m/s.
