The Agulhas, which is hundreds of kilometers long and over 2,000-meters deep, transports large amounts of ocean heat and is considered to have an influence not only on the regional climate of Africa, but on global climate as part of the ocean’s global overturning circulation.
How do ocean currents affect Africa?
The Agulhas Current transports warm tropical Indian Ocean water southwards along the South African coast. It modulates the rainfall along the east coast and interior regions of South Africa by providing the latent heat of evaporation needed for onshore wind systems to pick up moisture and carry it inland.
What are the 5 major ocean currents?
There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current” (Ross, 1995).
Which type of ocean current affects climate?
Horizontal currents moving northward or southward may carry warmed or cooled water for very long distance. The displaced warm water raises the temperature of the air while the cold water cools the air, and the land surface where the blows.
What are the 4 main ocean currents?
Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.
How does the Benguela Current affect the climate of western Africa?
The Benguela Current draws icy-cold waters from the Southern Ocean and carries them northward along the coast of Africa. … Because of these cold waters, rain clouds do not develop over the southwest coast of Africa, contributing to the parched climate of the KALAHARI and Namib deserts.
What are the ocean currents of South Africa?
South Africa’s two prevailing currents — Benguela and Algulhas, which meet at the Cape of Good Hope — make it one of the most dynamic landscapes in the world. Nowhere else are two contrastingly different ecosystems found in such close proximity.
