Abstract

A microphysical model is presented which can be used to provide first approximations of vertical extinction profiles for low stratus subclouds. The thermodynamic portion of the model is based on particle growth models by Hanel, drop-size distributions by Duncan and Low, or Shettle and Fenn, bulk phase change thermodynamics, and a mass balance formulation. Complex indices of refraction are estimated using mixture rules by Hanel, and transmission characteristics are determined by using Mie theory. Results obtained for adiabatic and nonadiabatic conditions are presented.
