Abstract: Experiments showed that, when a brass cube coated with transparent bubble-free ice or opaque ice containing a high concentration of air bubbles was allowed to slide down an opaque or transparent ice incline, temperature ...

Abstract: Experiments showed that, as an ice specimen evaporated by exposure to a stream of dry nitrogen, a temperature gradient was created in the surface of the specimen, which became electrically charged. The charge was positive ...

Abstract: When ice-coated spheres suspended from an insulating fiber were rotated rapidly through a stream of steadily falling natural snow crystals they acquired an electrical charge the magnitude of which increased markedly with ...

Abstract: A research airplane was used to study the microphysical characteristics of ice-free, nonprecipitating summertime cumulus clouds in Montana. Each cloud was penetrated at a multiplicity of levels encompassing, in general, a ...

Abstract: In order to assess quantitatively the role of drop disintegrations in producing the electrification of warm clouds, it is necessary to establish the electrohydrodynamical equations governing the stability of drops subjected ...

Abstract: A one-dimensional precipitative model of cloud electrification is outlined in which field growth results from the operation of either in inductive or non-inductive mechanism. The cloud is cylindrical, of finite dimensions, ...

Abstract: A stochastic model of ice particle multiplication is outlined in which ice splinters are produced by riming and possibly also by the splintering of individual drops on freezing. The splinters may grow into rimers or be ...

Abstract: The calculations of Gay et al. of the terminal velocities of charged hydrormeteors in the presence of electric fields have formed the basis of computations of the charging current density J flowing through a thunder-cloud ...
