The horizontal dark gray contour represents the typical depth of the winter mixed layer, which generally ...A detailed study of the mesoscale structure and variability of the upper 500 m layer of the Agulhas Current off Durban has shown that the Agulhas Current is ...Throughout the Agulhas Current at central and intermediate depths waters are cooler in summer and this is due to the upward tilt of the isopycnals, consistent with stronger geostrophic transport. Seasonality is also evident at depth, where North Atlantic Deep Water has a stronger equatorward flow during winter when the Agulhas Current is …The Agulhas Current is one of the major currents of the world ocean. In the network of currents that connect the major ocean basins, it forms a key link. This linkage may be of critical importance in the way the ocean affects the earth's climate and climate change. Based on the research findings of 60 years, the author describes the origins of …A stronger Agulhas Current has more inertia so the potential for stretching is larger (related to conservation of the Bernouilli function [Ou and de Ruijter, 1986]). The current can then more easily detach from the continental slope by interface outcropping, creating a free streamline. Due to the convex curvature of the African coast a stronger ...Apr 29, 2021 · For the Agulhas Current region, the high density of vessel traffic can provide new means to study and monitor intense upper ocean currents with more detailed resolution and precision. Key Points The high density of vessel traffic and associated Automatic Identification System messages provide means to derive the oceanic surface current Nov 9, 2016 ... The Agulhas Current has not intensified since the early 1990s, but has instead broadened as a result of more eddy activity.Agulhas current: a warm, fast-moving high-saline current that moves southward down the east coast, its flow directed by topography. As you can see, the Algulhas breaks from South Africa’s coastline at Port Elizabeth and begins its anticyclonic path, turning back (retroflecting) into the Indian Ocean, while spiraling off in select zones along ... When this happens, the curved current narrowly focuses the wave’s energy, like an optical lens can powerfully focus light into a single beam. Dr. Libe Washburn, a geography professor at the University of California, Santa Barbara, explains what occurs to waves interacting with a current like the Agulhas.Nov 26, 2022 ... southern Indian Ocean Agulhas Current, surface oceanic current that forms the western boundary current of the southern Indian Ocean.Feb 9, 2021 · 2 Satellite and Modeling Data for Waves in the Agulhas Current. The Agulhas current system is one of the most intense western boundary currents, with velocities exceeding 2.5 m s −1 along the East coast of South Africa, before retroflecting back into the Indian Ocean with large ring eddies shed in the South Atlantic Ocean (Beal et al., 2011 ...

There is an anti-correlation between Agulhas Current transport and Agulhas leakage (R = −0.67), whereas Agulhas Current transport correlates positively with Agulhas Return Current transport (R = 0.89). The geostrophic volume transport of the Agulhas Current, as referenced to LADCP, is 73 Sv, and is just 3% different from the direct LADCP transport estimate. The most recent full depth estimate of Agulhas Current transport in the literature is given by Toole and Warren [1993], who estimate a geostrophic volume transport of 85 Sv.Benguela Current in the South Atlantic Gyre. The Benguela Current / b ɛ ŋ ˈ ɡ ɛ l ə / is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre.The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela front in the north, at around 16°S.The current is driven by the …The Agulhas Current is an energetic current driven by the wind field over the Indian Ocean. It has a profound effect on the climate and the coastal ecosystem of South Africa and plays a key role ...Feb 5, 2009 · The dots are biennial transport values, the lines represent the best linear fit, and the gray areas are the 95% confidence interval of these fits. There is an anti-correlation between Agulhas Current transport and Agulhas leakage (R = −0.67), whereas Agulhas Current transport correlates positively with Agulhas Return Current transport (R = 0.89).

IntroductionThe greater Agulhas Current system forms the intensified western component of the subtropical gyre of the South Indian Ocean (Stramma and Lutjeharms, 1997).The Agulhas Current is supplied with Indian Ocean Tropical Surface Water of lower salinity (34.8–35.1) from the tropics (Gordon et al., 1987) and with more …Probabilistic estimates of ice impact loading on the propulsion systems of vessels designed to operate in polar waters are necessary to assess the adequacy of current design …Agulhas Current, surface oceanic current that forms the western boundary current of the southern Indian Ocean. It flows southward along the southeast coast of Mozambique and the coast of South Africa before turning eastward to join the flow from Africa to Australia. Mozambique Current. The Mozambique Current is an ocean current in the Indian Ocean, usually defined as warm surface waters flowing south along the African east coast in the Mozambique Channel, between Mozambique and the island of Madagascar . The classical definition of the Mozambique Current is that it is a strong, steady, western boundary ...The Agulhas Current and the Agulhas Retroflection can give rise to immense "rogue waves" that can even threaten supertankers. For that reason, mariners who successfully navigated the Cape of Good Hope frequently breathed a sigh of relief. On rare occasions, however, the clouds part and provide a spectacular view for hundreds of miles. The Agulhas Current (AC) is a critical component of the global ocean circulation. Climate models consistently project the AC to decline in the 21st century. Previous studies typically attributed the weakening of AC to changes in Indian Ocean wind and/or a decline of the Indonesian Throughflow (ITF) transport. However, our analysis …It has been observed a closed correlation between the transport of this current and the shedding of rings (Goni et al, JMR, vol.55, 861-883, 1997). Monitoring both the Agulhas transport into the South Atlantic in the upper kilometer of the ocean and the number of rings shed at its retroflection provides a means of detecting any substantial ... The second swiftest current in all the world's oceans, the Agulhas is deadlier than the swiftest current (the Gulf Stream) because the Gulf Stream moves through open waters of the Atlantic. But the Agulhas travels swiftly between two bodies of land--Madagascar and Mozambique (downward arrow on map). Furthermore its waters flow in the opposite ... The ADT data identify the ring's track, showing that it was shed by the Agulhas Current retroflection in November 2009 and propagated northwest rapidly during the first 2 months (mean speed of about 10 cm s −1) but slowed down substantially (3–4 cm s −1) between March and July 2010, when it was last detected.
