| contents | Wind-wave and ocean current interactions affect critical coastal and oceanic processes, yet modeling these interactions presents significant challenges. The western North Atlantic Ocean provides an ideal test environment for coupled hydrodynamics and wind wave models, thanks to its energetic surface currents such as the Gulf Stream. This study evaluates a high-resolution coupled SCHISM WWM III model, utilizing NOAA's 'STOFS-3D-Atlantic' computational mesh, while incorporating three-dimensional baroclinic dynamics to account for density stratification effects. We evaluate the model's calculated water level and tidal predictions against NOAA tide gauge measurements during December 2016. The coupled model demonstrates robust skills in reproducing tidal constituents, non-tidal components, and total water level predictions along the U.S. East and Gulf of Mexico Coasts. In addition, we systematically evaluate three wave physics parameterizations (Ardhuin, Makin and Stam, and Cycle Three) in the spectral wave model to quantify their effects on the modeled wave characteristics. This validated modeling framework enhances our ability to understand and predict complex coastal and oceanic processes, offering significant applications for coastal management, maritime operations, and climate adaptation planning throughout the western North Atlantic region. |
