It is shown, by use of Langmuir's precipitation growth data and Ludlam's hailstone heat economy data, that the glaze-ice thunderstorm charge generation mechanism suggested by E. J. Workman and the author is consistent with the thunderstorm cell development pattern observed by Workman and the author. The environment of charge separation is found theoretically. It also is shown that the initiation of precipitation in Midwestern thunderstorms without the involvement of ice crystals is consistent with Langmuir's cloud-droplet growth theory.
* NMIMT has been studying thunderstorm-charge generation under U. S. Army Signal Corps sponsorships since 1946.
