Viscosity parameterization and the Gulf Stream separation
Recent advances in computer architecture allow for numerical integration of state-of-the-art ocean models at basin scale with a grid resolution of 1/10 # or higher. At that resolution, the Gulf Stream's separation at Cape Hatteras is well simulated, but substantial di#erences from observations...

| Summary: | Recent advances in computer architecture allow for numerical integration of state-of-the-art ocean models at basin scale with a grid resolution of 1/10 # or higher. At that resolution, the Gulf Stream's separation at Cape Hatteras is well simulated, but substantial di#erences from observations are still observed in its path, strength, and variability. Several high resolution (1/12 # ) North Atlantic simulations performed with the Miami Isopycnic Coordinate Ocean Model (MICOM) are discussed and the results suggest that, even with such a fine grid spacing, the modeled large scale circulation is still quite sensitive to choices in forcing and viscosity parameterization. 1. |
