Abstract

The CUDM system provides transport and dispersion modeling capability at the urban scale. It simulates the mean flow, turbulence and concentration fields in urban areas. The system involves a cascade of meteorological models from the operational regional model to an urbanized meso-scale model that in turn drives a CFD flow model running at the urban scale. This CFD model simulates mean wind and turbulence fields that can feed dispersion models. The presentation will briefly describe the current state of the CUDM system, present results obtained over Vancouver during the Olympics and over Toronto during the G8/G20 summit meetings, and compare the different configurations.
