Abstract: The growth of electric fields in clouds resulting from charge rearrangement due to particle interaction and translation is calculated under the assumption that the initial electrification is provided by the fair weather ...

Abstract: The physical factors governing the induction charge separation mechanism in thunderstorms are discussed. Evidence is presented indicating that rebounding collisions between hailstones and cloud droplets are not (as suggested ...

Abstract: The lack of detailed information of the drag forces of cloud droplets during accelerated motion has made it necessary to assume that steady-state drag forces can be used to predict their motion at all times. This assumption ...
