Advances in parallel computing provide opportunities for improving numerical simulation methods for atmospheric transport and dispersion. Wind simulation over complex terrain with resolutions on the order of meters can now be executed in nowcasting and forecasting modes. However, the choice of numerical methods and the issues of subgrid-scale and near-wall modeling of turbulence become critical for making the most out of many-core computing. Within the context of immersed boundary methods, it will be shown that wind-field reconstructions are strongly coupled to the subgrid-scale viscosity, and fine tuning of the turbulence-model implementation can improve predictions markedly. The success of the Bayesian inference engine, employed to reconstruct contaminant plume dispersion from multiple sources, will be demonstrated for a variety of release scenarios.

For accommodations based on disability, or more details, please call 325-6561. All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required.

The University of Oklahoma is a smoke-free / tobacco-free campus
