Parametric cquations dcscribing the growth of ice particles in the range 10-”-1 g are presented. Three subrangcs (10-11-5 X 5 X 10-s-10-4, and 10-4-1 g) are used. Thc parametric equations were developed with the aid of a complex method of calculating ice-particle growth. Two approaches to using the parametric equations in a simulation resembling a natural cloud situation are described. One meth...
