Nesting of Ocean Models to Evaluate Nonhydrostatic Effects

Paul Choboter


The Regional Ocean Modeling System (ROMS) is a hydrostatic free-surface ocean model designed to simulate medium to large-scale coastal ocean processes. The Unified Curvilinear Ocean Atmosphere Model (UCOAM) is a non-hydrostatic model developed by researchers at San Diego State. In this talk, we will discuss hydrostatic and non-hydrostatic effects, and report on preparations to couple the two models together. UCOAM will be nested within ROMS, and the nested model will be used to study realistic currents in Monterey Bay, where there the bottom bathymetry has steep canyons that may generate non-hydrostatic flows.
