Final Report on A. R. A. P.'s Model for the Atmospheric Marine Environment

Abstract

This report presents the results for the past year's developments for computing the detailed low-level atmospheric distribution of velocity, temperature, moisture, refractive index, and the turbulent variances of these quantities. A critical review of the present status of the model is presented along with results of new calculations. A calculation of fog evolution is presented to show a cold-water fog evolving into a warm-water fog as a result of radiational cooling. The evolution of breaking Kelvin-Helmholtz waves is also followed in a series of calculations which should lead to a better understanding of the dynamics of the inversion layer at the top of the atmospheric boundary layer. Detailed derivations of two proposed extensions to the model are presented. One involves a hybrid integral-differential description to permit approximate solutions to be obtained with less numerical effort, and the second involves the incorporation of precipitation into the two-phase representation of water in the atmospheric.
