| Abstract |
Laboratory experiments were conducted in a stratified towing tank to investigate plume dispersion in stably stratified flows. First, plume dispersion over an idealized terrain model with a simulated elevated inversion in the atmosphere was investigated. These results were compared with those of experiments previously conducted under simulated ground inversions. Second, plume dispersion in 1-layer stably stratified flows over a realistic terrain was also modeled. The plume dispersion patterns showed a strong interaction between the stratified flow and the rugged terrain features. Third, plume dispersion during inversion breakup was simulated. Results indicated that as soon as the convective layer built to reach the plume, pollutants were stirred and carried to the ground. |
