Abstract : Considered in the present study is the temporal and spatial theoretical description of circulation and mixing of sea water induced in an initially motionless, continuously stratified, uniformly rotating, baroclinic ocean by steady as well as transitory, axisymmetric, cyclonic atmospheric vortices. The nonlinear processes of lateral and vertical advection of momentum, heat, and salt are explicitly included in flux form in the governing hydro-thermodynamic equations. Lateral as well as vertical turbulent diffusion of momentum and thermal properties are included in gradient form, but all exchange coefficients are held constant, with assumed Prandtl numbers of unity in the respective horizontal and vertical directions. Additional pertinent constraints include constant Coriolis parameter, use of the hydrostatic approximation in an incompressible ocean, and imposition of the rigid-lid approximation along the sea surface. Time-marching numerical integration of an appropriate set of partly explicit and partly implicit finite-difference relations is used for obtaining solutions to the system of primitive equations.
