COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System)
Posted March 21, 2002,16:43
The atmospheric portion of COAMPStm represents a complete three-dimensional data assimilation system comprised of data quality control, analysis, initialization, and forecast model components. Features include a globally relocatable grid, user-defined grid resolutions and dimensions, nested grids, an option for idealized or real-time simulations, and code which allows for portability between mainframes and workstations. The nonhydrostatic atmospheric model includes predictive equations for the momentum, the non-dimensional pressure perturbation, the potential temperature, the turbulent kinetic energy, and the mixing ratios of water vapor, clouds, rain, ice, and snow, and contains advanced parameterizations for boundary layer processes, precipitation, and radiation.
