Is the Agulhas Current warm or cold?

Because it is fed from lower latitudes, the Agulhas Current is warm, ranging in temperature from 57 to 79 °F (14 to 26 °C) at the surface. The average temperature is lower in southern sections near Antarctica. The Agulhas is noted as a major western boundary current in the Southern Hemisphere.

What causes the Agulhas Current?

The Agulhas Current is formed by the confluence of the warm Mozambique and East Madagascar Currents, which meet south-west of Madagascar (not shown in the diagram). The cold Benguela Current originates from upwelling of water from the cold depths of the Atlantic Ocean against the west coast of the continent.

What is the tip of Africa called?

Which ocean current is the fastest?

The Gulf Stream The Gulf Stream is the fastest ocean current in the world with peak velocities near 2m/s. Shown to the left are velocity profiles across the Gulf Stream at the Straits of Florida and Cape Hatteras.

What is the largest current in the world?

The Antarctic Circumpolar Current The Antarctic Circumpolar Current is the largest current in the world. ‘It’s been estimated that this current is 110–150 times larger than all the water flowing in all the rivers of the world,’ says Dr Mike Williams.

How does the Agulhas Current affect climate?

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 is Agulhas Retroflection?

Abstract. The Agulhas Retroflection, as observed in late 1983, consists of the main Retroflection at 21°E with two large warm-core Agulhas rings to its west. It encircles a core of Agulhas water which was highly altered, by the action of the winter atmosphere, from the source Agulhas water.

Is the Agulhas Current Geostrophic?

Orange and red colors further offshore are indicative of the north-easterly flowing Agulhas Return Current. Cross-track geostrophic current velocities within the Agulhas Current core are often in excess of 2 ms−1 along both Tracks #020 and #198.

What is a richest country in Africa?

Nigeria Nigeria is the richest and most populous country in Africa. The country’s large population of 211 million is a likely contributor to its large GDP. Nigeria is a middle-income, mixed economy and emerging market with growing financial, service, communications, and technology sectors.

Why is Horn of Africa treacherous?

Cape Horn marks the point at which the Atlantic and Pacific Oceans meet – which is what makes the passage so treacherous. Extreme low-pressure systems whirl across the sea, creating the dreaded williwaw winds. These gusts are sudden, unpredictable and frequent – and with bigger winds, come bigger waves.

Why is Africa called Cape of Good Hope?

It is known for its spectacular scenery. It was originally named the Cape of Storms by Portuguese explorer Bartholomew Dias in 1488. It was later renamed, by King John II of Portugal, the Cape of Good Hope because of the great optimism engendered by the opening of a sea route to India and the East.

What was Africa called before?

Alkebulan What was Africa called before Africa? The Kemetic or Alkebulan history of Afrika suggests that the ancient name of the continent was Alkebulan. The word Alkebu-Ian is the oldest and the only word of indigenous origin. Alkebulan meaning the garden of Eden or the mother of mankind.

Which current travels faster?

Off the Atlantic seaboard of the United States, the Gulf Stream flows at a rate nearly 300 times faster than the typical flow of the Amazon River. The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour).

Which current is the fastest?

Gulf Stream The Gulf Stream is the fastest ocean current in the world with peak velocities near 2m/s.

Why is California current cold?

The water along the coast of California is cold for a couple of reasons. First, the California Current brings cold water from Alaska southward along the coast. And second, cold water from the deep ocean comes up to the surface through a process called upwelling. So water from the deep ocean is sucked to the surface.

Which ocean current is a cold current?

The cold current among the following given options is Labrador Current. This Labrador Current flows in the North Atlantic Ocean. The cold current flows till the Labrador coast from the Arctic Ocean. This cold wave also meets the warm waves that are moving and outward in Gulf Stream.

Which ocean current is warm?

What is the largest water current in the world?

The Antarctic Circumpolar Current The Antarctic Circumpolar Current (ACC) is the largest ocean current on Earth. It flows clockwise around Antarctica, linking the Atlantic, Pacific and Indian Oceans.

How much water does the Agulhas current transport?

about 70 million cubic metres per second Agulhas Current The amount of water transported amounts to about 70 million cubic metres per second, making it one of the largest western Boundary Currents in the world.

How does the Leeuwin current affect climate?

The Leeuwin Current is a warm ocean current which flows southwards near the western coast of Australia. Because of the Leeuwin Current, the continental shelf waters of Western Australia are warmer in winter and cooler in summer than the corresponding regions off the other continents.

In which ocean is the Humboldt Current?

southeast Pacific Ocean Peru Current, also called Humboldt Current, cold-water current of the southeast Pacific Ocean, with a width of about 900 km (550 mi). Relatively slow and shallow, it transports only 350,000,000–700,000,000 cu ft (10,000,000–20,000,000 cu m) of water per second.

Is the Indian Ocean warm or cold?

The Indian Ocean is the warmest ocean in the world. Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, at about 1.2 °C (34.2 °F) (compared to 0.7 °C (33.3 °F) for the warm pool region) during 1901–2012.

Is Somali Current a warm current?

A current in the northern Indian Ocean that reverses direction during the year. In the northern winter season, it is a warm current that is fed by an anticlockwise circulation in the Arabian Gulf and flows south-westwards along the coast of Somalia. With the onset of the summer monsoon, the circulation reverses.

Is the Brazil current warm or cold?

The Brazil Current is a weak western boundary current carrying warm subtropical water, which runs south along the coast of Brazil from about 9°S to about 38°S and is generally confined to the upper 600m of the water column.

What is the largest Geostrophic current?

The Antarctic Circumpolar Current It transports about 134 million cubic metres (4.7 billion cubic feet) of seawater per second over a path of about 24,000 km (about 14,900 miles) and is the most important factor in diminishing the differences between oceans.

What is a Geostrophic gyre?

3:11 4:28

How geostrophic flow is formed?

The rotation of the earth results in a “force” being felt by the water moving from the high to the low, known as Coriolis force. The Coriolis force acts at right angles to the flow, and when it balances the pressure gradient force, the resulting flow is known as geostrophic.

Why is Cape Horn weather so bad?

The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs. (Many take a detour through the islands and anchor to wait for fair weather to visit Horn Island, or sail around it to replicate a rounding of this historic point.)

Why is Cape Horn so windy?

The Horn sits at a latitude of 56 degrees south and is thus prone to intense westerly winds nicknamed the “furious fifties”. These winds are intensified at the Horn because of the funneling effect of the Andes Mountains and the Antarctic Peninsula that force the winds into the relatively narrow Drake Passage.
