Abstract

A detailed model of the melting, shedding, and wet growth of spherical graupel and hail is presented. This model is based upon recent experimental studies by Rasmussen et al. and Lesins et al. The model is presented in the form of five easy-to-use tables. Important quantities considered were the heat transfer. terminal velocity behavior, and shedding of liquid water.
