| description abstract | A numerical model based on the convective plumes observed in the convecting planetary boundary layer has been developed for material dispersion from both elevated and ground source releases. Mechanistic formulation, rather than parameterization, or statistical behavior of PBL phenomenon, has been used as a basis. This model uses two universal constants, the turbulent entrainment constant, a, and decay constant, A. The model results have physical significance with regard to the observed plume behavior in a convective field. An observed case of diffusion has been simulated. The model results are in reasonable agreement with the observation without introducing any adjustable parameters to improve the fit. | |
