Abstract:

As specified in the original proposal, there exits mounting evidence that the growth of strong electric fields - culminating in lightning - in the great majority of thunderstorms is intimately linked with - and probably contingent upon - the concomitant development of the ice-phase. Thus, significant progress in the elucidation of electrification mechanisms requires an improved understanding of the complex set of processes involved in cloud glaciation. Accordingly, primary emphasis has been devoted in this first year of a proposed 3-year study, to the analysis and interpretation of data emanating from major airborne experiments in which a primary objective was to seek a superior understanding of the initiation and development in cumulus clouds of the type which often become strongly electrified.
