1977 Status Report on Low-Level, Atmospheric Turbulence Model for Marine Environments.

Abstract

This report details the last year's developments to A. R. A. P. 's program for computing the detailed low-level atmospheric distributions of velocity, temperature, moisture, refractive index, and the turbulent variances of these quantities for marine environments. Effort has been divided between extending the model and in exercising the existing model to both exemplify expected phenomena and to compare with available observations. The model has been extended: to remove the hydrostatic approximation; to incorporate condensation and radiation into the two-dimensional, unsteady model; to incorporate terrain variation into the surface boundary conditions; and to determine the influence of particle size on the turbulent transport of aerosols. Sample calculations include fog episodes, diurnal variation of stratus over the ocean, the general structure of the tradewind boundary layer, and an evaporatively cooled gust front. Although verification tests have not been adequate to provide a detailed assessment of accuracy, the model results are generally quite consistent with available observations. (Author)
