Abstract: The assumptions, techniques and methods of improving Gaussian plume modeling are briefly reviewed. Then the statistical theory for the diffusion of a substance S into a turbulent flow in homogeneous and inhomogeneous flows, ...

Abstract: A theory for the velocity deficit in the wake of a moving vehicle in still air is derived from a perturbation analysis of the equations of motion. By suitable assumptions, expressions are found for the turbulent energy ...

Abstract: The theoretical and laboratory studies on mean velocity and temperature fields of an unsteady atmospheric boundary layer on sloping surfaces reported here were motivated by recent field observations on thermally driven ...

Abstract: Theoretical and field observational studies on mean velocity and temperature fields of quasi-steady nocturnal downslope (katabatic) flows on sloping surfaces are reported for the case of very wide valleys in the presence ...

Abstract: A finite-difference highway model is presented which uses surface layer similarity theory and a vehicle wake theory to determine the atmospheric structure along a roadway. Surface similarity is used to determine the wind ...

Abstract: Past research has suggested that the evening transition in complex topography typically has several main features, such as (a) continued weak upslope flows persisting 3?5 h after sunset (if the sidewalls of the valley ...

Abstract: merging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific and societal interest in mountain meteorology. To address ...
