Book Description
Considered are steady, wind-driven currents in a two-layer model ocean, confined within a rectangular basin with a horizontal sea bed. The horizontal velocities are assumed independent of elevation within each layer of this finite difference approximation to the continuously stratified real ocean. Neglecting nonlinear field accelerations, a frictional model for the entire basin is formulated which allows for vertical, but not horizontal, transfer of horizontal momentum due to turbulence. The exchange of horizontal momentum between layers and to the sea bed is provided through the assumption of interlayer and bottom stresses, which are assumed proportional to the vertical contrast of horizontal velocity across the appropriate interface. The constants of proportionality, which are estimated from considerations of the observed circulation, play decisive roles in controlling the circulation patterns within each layer and the internal dissipation of energy from the steady organized flow. The solution, obtained for a purely zonal wind stress which varies latitudinally as a cosine, depicts an anticyclonic circulation within the lower layer which is intensified more to the west than is the anticyclonic gyre within the upper layer. Numerical calculations were performed for a range of physical parameters. ...
