Abstract : The general circulation in the Gulf of Mexico is treated with two-layer ocean models. Scaling of vorticity equation for the upper layer with the motionless lower layer indicates that the inertia, horizontal eddy viscosity and wind-stress terms are unimportant compared with planetary vorticity and friction (proportional to velocity) terms for time scales longer than a few months and that a non-stationary motion like Loop Current may develop within a few weeks. Analytical solutions of the linearized transport vorticity equation with planetary vorticity and frictional terms are obtained by use of a Green function method for a rectangular, two-ports basin similar to the Gulf. An equation for change of the upper layer depth along a streamline is obtained from the integral relationships of the non-linear equations of motion. (Author)
