Abstract: he importance of bottom topography in the linear baroclinic instability of zonal flows on the ? plane is examined by using analytical calculations and a quasigeostrophic eddy-resolving numerical model. The particular focus ...

Abstract: his study examines eddy-driven material transport by analyzing trajectories of Lagrangian particles in an idealized model of the Southern Ocean. The main focus is on the direction of the transport in the latitude?depth ...

Abstract: AbstractThe modulation of large-scale eddying flows by gentle variation in topography is examined using a combination of direct numerical simulations and theoretical arguments. The basic state is represented by a laterally ...

Abstract: The zonally localized instability of a zonal flow that has an added meridional component in the zonal interval |x| < a is examined. The flow occurs on the infinite ? plane and is analyzed in a two-layer model. The basic ...

Abstract: The linear stability of nonzonal flow, uniform in the alongjet direction on a beta plane, is studied. The flow is balanced by a forcing term in the potential vorticity equation. The problem is analyzed in both barotropic ...

Abstract: This article continues the study of the radiation of energy from nonzonal ocean currents in the nonlinear regime. The effects of the interactions between different waves in the initial spectrum on the radiating properties ...

Abstract: The energy radiation from oceanic boundary currents is assumed to be one of the main mechanisms responsible for the production of the highly energetic eddy field in the interior of the ocean. The efficiency of the process ...

Abstract: An extension of Walin?s water mass transformation analysis is proposed that would make it possible to assess the strength of the adiabatic along-isopycnal component of the meridional overturning circulation (MOC). It is ...

Abstract: Multiple zonal jets are observed in satellite data?based estimates of oceanic velocities, float measurements, and high-resolution numerical simulations of the ocean circulation. This study makes a step toward understanding ...
