The Sources and Mixing Characteristics of the Agulhas Current
|
ABSTRACT
Recent observations taken at four principal latitudes in the Agulhas Current show that the watermass properties on either side of its dynamical core are significantly different. Inshore of its velocity core are found waters of predominantly Arabian Sea, Red Sea, and equatorial Indian Ocean origin, while offshore waters are generally from the Atlantic Ocean, the Southern Ocean, and the southeast Indian Ocean. For the most part, the inshore waters approach the Agulhas Current th...

Underestimation of latent and sensible heat fluxes above the Agulhas Current in NCEP and ECMWF analyses
Journal of Climate
; ABSTRACT The Agulhas Current is the major western boundary current of the Southern Hemisphere. South of Africa it retroflects back into the southwest Indian Ocean, transporting relatively warm water into the midlatitudes. Large sensible and latent heat transfers from the Agulhas Current and its

Ocean-atmosphere interaction in the Agulhas Current region and a South African extreme weather event
Weather and Forecasting
; (Manuscript received 25 October 2000, in final form 30 November 2001) ABSTRACT Ocean-atmosphere interaction above warm western boundary currents such as the Gulf Stream, the Kuroshio Current, and the Agulhas Current often leads to very high evaporation rates. In the case of the Agulhas Current,

Evidence for the influence of the Agulhas Current on regional atmospheric circulation patterns
Journal of Climate
; ABSTRACT The Agulhas Current is much the strongest western boundary current in the Southern Hemisphere transporting about 65 Sv of warm water along the southeast coast of Africa. South of Africa, it retroflects back into the South Indian Ocean and flows east as the Agulhas Return Current. Large

Stability of western boundary currents with an application to Pulselike behavior of the Agulhas Current
Journal of Physical Oceanography
; ABSTRACT The northern Agulhas Current off South Africa displays very steady flow characteristics. Roughly five to six times per year the flow is disrupted by the passage of large solitary meanders, propagating downstream. Observations obtained from moored current meters show that these so-called

Modeling the Variability of the Greater Agulhas Current System
Journal of Climate
; ABSTRACT An eddy-permitting, regional ocean model has been used to examine the variability in the source regions of the Agulhas Current on a range of time scales. These source regions are the East Madagascar Current, the flow through the Mozambique Channel, and the recirculation of the southwest

Is Interleaving in the Agulhas Current Driven by Near-Inertial Velocity Perturbations?
Journal of Physical Oceanography
