Abstract: A simple, two-layer, quasi-geostrophic model is used to investigate the stability of baroclinic currents confined to a finite length scale L in a basin of considerably larger dimension (4L). The current distributions studied ...

Abstract: A plate tilted at 42° from the horizontal is oscillated along its length with frequency ? and amplitude a in a linearly stratified fluid (salt water) of kinematic viscosity ?. If the Reynolds number Rc = a(?/?)½ is small, ...

Abstract: Several aspects of thermal convection in the presence of a lateral shear associated with either a shear line [with velocity V(x)] or a circular vortex [with azimuthal velocity V(r)] are considered. Parameter settings that ...

Abstract: A two-layer model is constructed for wind-driven flow over topography in a closed polar basin where thevariation of Coriolis force with latitude is negligible. The model equations are reduced using scales appropriate for ...

Abstract: Baroclinic instability of a circular current is modified by the presence of a unidirectional bottom slope.An analytical theory is developed for the slightly unstable flow regime over a weak slope. The presence of theslope ...

Abstract: We consider the instability properties of a circular current in the upper layer of a two-layer quasi-geostrophic ocean over a unidirectional slope. This particular flow-topography geometry is intended as a crudemodel of ...

Abstract: A simple parallel flow model is derived for a thin (depth to length ratio ?1) Hadley circulation in a two-dimensional box with rigid horizontal boundaries maintained at a temperature which increases linearly with the ...

Abstract: The Eady problem concerning the stability of quasi-geostrophic baroclinic flows which have uniform vertical shear is generalized to include time-dependent basic flows. By means of a simple transformation an exact solution ...
