Abstract: The two principal physical mechanisms for the formation of precipitation are considered to be the Bergeron-Findeisen ice-crystal process and the collision of particles of unlike size in the gravitational field. Quantitative ...

Abstract: The partial chemical analysis of some ninety samples of fog and cloud water is reported. The fog samples were collected at four locations along the northeast coast of North America, and the cloud samples were obtained on ...

Abstract: It is held that entrainment is a necessary dynamic consequence of the vertical stretching of an accelerated convective column. On this basis, equations are developed for the rate of entrainment, the vertical divergence and ...
