Abstract: Work has focused primarily on simulations of the coastal atmosphere, and on building a coupled regional ocean-atmosphere model, based on the Naval Research Laboratory - COAMPS and Rutgers/UCLA ROMS models, for use on multiple processor, cluster systems. Progress to date includes the development of a processor management code module using the Model Coupling Toolkit (MCT) (Argonne National Laboratory). The management module is able to run both COAMPS and ROMS on independent processors. Model initializations for both the ocean and atmosphere have been developed for an idealized, linear coastline, using conditions similar to summer upwelling events along the U.S. west coast. Comparison of the coupled simulations with uncoupled and partial coupled cases suggests that the dynamics of the near shore upwelling region are greatly affected by coupled processes. For example, in cases without coupling, offshore mass transport is nearly constant across the coastal shelf Coupling generates a more realistic mass - transport results that gradually increases over a distance of 10-20 km off shore. Near shore currents are also affected with the coastal jet decreasing near the coast where the wind stress is reduced.
