Parameterization of Ice Growth for Numerical Calculations of Cloud Dynamics.
ResearchPublished 1971
Parametric equations describing the growth of ice particles are presented in the range 10 to the minus 11th power g to 1 g. The parametric equations were developed with the aid of a complex method for calculating ice-particle growth. Two approaches to using the parametric equations in a simulation resembling a natural cloud situation are described. One method breaks the ice-particle spectrum into three components and monitors the sizes of each. The other assumes a size distribution that can be characterized by a "growth-median" size, so that only one size need be monitored to describe the rate of growth. The parametric method is compared with more complicated methods in a simulated cloud environment, and the results are regarded as satisfactory. 34 pp. Ref.
