The Impact of Aerosol Prediction in Cloud-Scale Numerical Prediction Models (Invited)
At Environment Canada, research is currently underway to investigate the impact of the chemistry-dynamics interaction to NWP through a fully coupled model (GEM-MACH) with a 2.5-km grid spacing. The NWP model uses a detailed two-moment bulk microphysics scheme, which provides the link between the chemistry and meteorology of the modeling system. Results will be presented from the GEM-MACH/GEM modeling system. Emphasis will be given on providing a detailed overview on how predictive aerosols affect NWP through the various processes that depend, directly and indirectly, on the aerosol input into the microphysics scheme.
