Abstract

"Considerable interest has developed in recent years to understand transport phenomena in thermally stratified boundary layers. More complete knowledge in this field is needed to improve the prediction of the diffusion of air pollutants in the lower atmosphere as well as in forecasting air-water circulation for weather conditions.

The atmospheric boundary layer is modeled using the equations of continuity, momentum, energy, and concentration. Closure of this set of partial differential equations is hindered by the turbulence terms. Using turbulence kinetic energy, the system of equations is closed by internally determining the exchange coefficients of heat, mass, and momentum along with other atmospheric parameters. This approach makes it possible for the history of turbulent motion to be taken into account. Verification of this model is made by systematically comparing the numerical results with available wind tunnel data for neutral, stable, and unstable conditions. Application of the model is made to study the formation of advection fogs occurring over cold sea surfaces. However, the predicted results of liquid water and water vapor contents have yet to be verified with actual data obtained from field measurements"--Abstract, page ii.
