1. Introduction Western boundary currents (WBCs) are dominant features in the world oceans. Here the stability of such currents will be investigated with special emphasis on the Agulhas Current off South Africa. A key feature of the Agulhas is that it establishes a link in the global thermohaline circulation as it exports properties, like salt and heat, from the Indian to the Atlantic Ocean [see De Ruijter et al. (1999a) for a review]. The Agulhas Current can be divided into two regions

as La t decreases (see section 3 ). One advantage of (9) is that it allows the definition of friction velocities due to shear and due to the wave that are additive, yielding the sum . The present approach partially resembles the modification of the surface shear stress to account for wave effects in the study of the Ekman–Stokes boundary layer by Polton et al. (2005) , where, however, Earth’s rotation effect was taken into account. c. A model for the current profile To obtain a model for

1. Introduction Boundary processes exert a strong influence over large-scale circulation patterns and energy budgets in both the ocean and the atmosphere ( Wunsch 1970 ; Schneider et al. 2003 ). In the ocean, boundary currents over continental shelves and slopes can influence water mass modification ( Whitworth et al. 1998 ; Orsi et al. 2002 ; Flexas et al. 2015 ), eddy formation ( Molemaker et al. 2015 ; Gula et al. 2015 ), and the generation of potential vorticity (PV) anomalies

mesoscale flow over rough topography energizes the internal wave field at rates similar to those observed by Naviera-Garabato et al. (2004) in the Southern Ocean. Of direct relevance to this study, Dewar et al. (2015) argued that eastern boundary currents appeared capable of directly driving mixing by centrifugal instability (CI). The sequence of events leading to mixing were that poleward-flowing currents, like the California Undercurrent (CUC; see Fig. 1 ), develop strips of strong negative

Atlantic Ocean at intermediate depths. Near the outer continental shelf and shelf break, the West Greenland and Labrador Currents transport Arctic-origin water equatorward ( Fig. 1 ). Offshore of these currents, on the continental slope, resides a deep-reaching boundary current that transports the warm and salty waters of subtropical origin plus the Sverdrup return flow of the wind-driven subpolar gyre. For the purpose of this paper, we will refer to this slope flow as the Irminger Current. Farther
