Abstract : The dynamics of the eddy shedding by the Loop Current in the Gulf of Mexico have been investigated using three nonlinear numerical models: two-layer, barotropic, and reduced gravity. The barotropic and reduced gravity models demonstrate the individual behavior of the external and internal modes, and provide insight into how they interact in the two-layer model. Because of the economy of the semi-implicit free surface models, it was possible to perform over 100 experiments to investigated the stability properties of the Loop Current. Typically the models were integrated 3 to 5 years to statistical equilibrium on a 1600 x 900 km rectangular domain with a resolution of 20 x 18.75 km. Prescribed inflow through the model Yucatan Channel was compensated by outflow through the Florida Straits.
