A prognostic turbulence scheme for the nonhydrostatic plume model ATHAM

Summary: | Herzog et al presents a turbulence scheme for the Active Tracer High-resolution Atmospheric Model (ATHAM) to parameterize the effect of subgrid-scale turbulence. The presence of high tracer concentrations in a particle-laden plume is taken into account, as well as supersonic affects at low Mach numbers. Numerical simulations of convective plumes of typical Plinian volcanic eruption with the nonhydrostatic plume model ATHAM reveal that a complex treatment of turbulent quantities is necessary in order to capture the bulk characteristics of the plume height, the horizontal extent, and plume development in time. |
