Agulhas leakage, the warm and salty inflow of Indian Ocean water into the Atlantic Ocean, is of importance for the climate-relevant Atlantic Meridional Overturning Circulation. South of Africa, the eastward turning Agulhas Current sheds Agulhas rings, cyclones and filaments of order 100km that carry...

Using ocean models of different complexity we show that opening the Indonesian Passage between the Pacific and the Indian oceans increases the input of Indian Ocean water into the South Atlantic via the Agulhas leakage. In a strongly eddying global ocean model this response results from an ...
The Agulhas leakage brings warm and saline water from the Indian Ocean into the South Atlantic, forming part of the returning branch of the global thermohaline circulation, an important component of climate. We develop a new method using the passive tracer spice, to estimate Agulhas leakage ...
The interoceanic transfer of seawater between the Indian Ocean and the Atlantic, ‘Agulhas leakage’, forms a choke point for the overturning circulation in the global ocean. Here, by combining output from a series of high-resolution ocean and climate mo
he Agulhas Current transport of heat and salt from the Indian Ocean into the South Atlantic around South Africa (Agulhas leakage), can affect the Atlantic meridional overturning circulation (AMOC) and, thus, influence global climate. However, efforts to elucidate forcing mechanisms connecting the ...

The results show that in addition to the Agulhas Leakage and the Agulhas Return Current, the Agulhas waters flow southeastward and enter the ACC at several mixing hot spots that are instigated by topographic obstacles. The most notable intrusion into the ACC occurs at the southwest Indian Ridge,...

[1] The Agulhas Leakage represents a significant portion of the warm, surface return flow of the global overturning circulation and thus may be an important feedback in the ocean climate system. Models indicate that reduced leakage could be caused by a stronger Agulhas Current and/or a more ...
