Abstract

A now well established model [6] is used to analyze the evolution of raindrops in warm clouds from the initial stage of nucleation to clouds maturation and active raindrops formation. The numerical simulation performed shows that the mixing ratio of the raindrops in the active warm cloud follows a law of Gauss-Laplace type, and we bring evidence of it from the test. We therefore can determine the period of acuteness in the production of the raindrops.

Keywords and phrases: clouds, raindrops, microphysics, dynamics, thermodynamics, mixing ratio, Gaussian distribution.
