AgulhasCurrent is the Western Boundary Currentof the South-West Indian Oceanand is part of the westward flowing South Equatorial Current. It flows down the east coast of Africafrom 27°S to 40°S. It is narrow, swift and strong.
The sources of the Agulhas Current are the
East Madagascar Current, the Mozambique Currentand a reticulated part of the Agulhas Current itself. The flow of the Agulhas Current is directed by the topography. The current follows the continental shelf from Maputoto the tip of the Agulhas Bank(Cape Agulhas). Here the momentum of the current overcomes the vorticitybalance holding the current to the topography and the current leaves the shelf. In the South-East Atlantic Oceanthe current retroflects(turns back on itself) in the Agulhas Retroflection, becoming the Agulhas Return Current. This returns to the Indian Oceanand contributes the major part of the volume of the Agulhas Current by recirculation.
Where the Agulhas turns back on itself the loop of the retroflection pinches off periodically, on average about once every two months, releasing a retroflection eddy into the
South Atlantic Ocean. This retroflection eddy or "Agulhas ring" enters the flow of the Benguela Currentand is translated north-westward across the Atlantic Ocean.
