Abstract: A six-level ocean model is coupled with Hibler's sea-ice model to examine oceanic roles in seasonal ice advance off the east coasts of continents. The model has the straight coast to the west and the steplike shelf break, ...

Abstract: The process of meander growth on and eddy detachment from an eastward flowing oceanic jet, which is modeled after the Gulf Stream east of Cape Hatteras, is studied using numerical solutions of nonlinear equations. The ...

Abstract: Asymmetric instability of a circular Gaussian ring and evolution of a ring shape in a nonlinear case are studied using a two-layer quasi-geostrophic model on an f plane. Ring behavior is classified on an F-? plane with ...

Abstract: A rectangular-basin ocean, driven by buoyancy and density fluxes in its northern and southern portions, is studied using a two-level model. Only baroclinic motion is induced under the conditions of 1) no wind, 2) neither ...

Abstract: In a two-layer model with a rigid surface and a flat bottom on an f-plane, an internal Kelvin wave is forced by quasi-geostrophic, mesoscale meanders of a coastal current. These meanders are assumed to be quasi-periodic ...

Abstract: A quasi-geostrophic model of a three-layer fluid on an f-plane is employed to study instability of a current flowing over a uniform bottom slope with isobaths parallel to the current. The model has a basic flow only in the ...

Abstract: The effect of meridional movement of the curl τ = 0 line on the intergyre transport is investigated by passive tracer experiments in a double gyre circulation. Furthermore, the contribution to temperature distribution is ...

Abstract: The process of eddy detachment from a strong, eastward-flowing oceanic jet, which is modeled after the Gulf Stream, is studied using a two-layer quasi-geostrophic model. Numerical calculations are performed, in which an ...

Abstract: The 3D pathways of the Indonesian Throughflow (ITF) in the Indian Ocean are identified using an OGCM, with a combined set of tools: 1) Lagrangian particle trajectories, 2) passive tracers, and 3) active tracers (temperature ...

Abstract: A dynamic?thermodynamic sea ice model with the ocean mixed layer forced by atmospheric data is used to investigate spatial and long-term variability of the sea ice cover in the Arctic basin. The model satisfactorily ...
