Abstract: The nonlinear dynamics of baroclinically unstable waves in a time-dependent zonal shear flow is considered in the framework of the two-layer Phillips model on the beta plane. In most cases considered in this study the ...

Abstract: A study is made of the thermocline and current structures of a subtropical/subpolar basin. Tis paper explores the shape of the interface, and the flow patterns when the lower layer is infinitely thick. Simple frictional ...

Abstract: The instability of jets in the context of the shallow-water model for both quasigeostrophic (QG) and non-QG parameters is studied. First, the linear stability problem is solved for a wide range of Rossby and Froude numbers ...

Abstract: In this article, the effect shelflike topography has on the stability of a jet that flows along the smooth shelf is addressed. The linear stability problem is solved to determine for which nondimensional parameters a shelf ...

Abstract: We examine the nonlinear evolution of barotropic ?-plane jets on a periodic domain with a pseudospectral. A calculation of the linear growth rate yields an infected U-shaped curve on the ? versus k0 plane which separates ...
