South Atlantic Bight Numerical Model Application - Executive Summary

摘要

Circulation of the water masses in the South Atlantic Bight (SAB) has been modelled using a three-dimensional, physically comprehensive General Circulation Model (GCM) that incorporates realistic turbulent mixing and air-sea momentum, heat and mass transfer. Open ocean boundary conditions for this model have been deduced from a Characteristic Tracing Model (CTM 81) that uses simplified physics to derive the currents from prescribed water density and sea-surface and wind stress fields. The two models in consort with each other provide current distributions in the SAB at various depths in the water column. The capabilities of the models have been demonstrated by deducing the circulation distribution for typical seasons.
