What does Benguela mean? bengālə A strong ocean current in the South Atlantic, flowing northward along the SW coast of Africa. noun. A cold ocean current originating in the Southern Ocean surrounding Antarctica, thence flowing northwards up the west coast of Africa as far as Angola.
Is Falkland current warm or cold?
The Falkland Current (also called Malvinas Current or Falklands Current) is a cold water current that flows northward along the Atlantic coast of Patagonia as far north as the mouth of the Río de la Plata. This current results from the movement of water from the West Wind Drift as it rounds Cape Horn.
What causes the Benguela Current?
The Benguela Current is driven by the prevailing South Easterly trade winds of the South Atlantic Ocean. Inshore of the Benguela Current proper, the south easterly winds cause coastal upwelling, forming the Benguela Upwelling System. … The intensity of upwelling events is determined by wind strength.
What are the 3 major ocean currents?
The produce large circular currents in all the ocean basins. Currents, The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.
What are the 3 types of ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean’s surface. …
- Thermohaline circulation.
Which current is the coldest?
The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia.
Is Peru current warm or cold?
As it is a cold current, except at times of the phenomenon known as El Niño (q.v.), the Peru Current brings fog to the nearby coast but also helps to keep the coast one of the most intensely arid areas in the world.
Is Brazil Current a warm current?
The Brazil Current is a warm water current that flows south along the Brazilian south coast to the mouth of the Río de la Plata.
What are the 5 major currents?
Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The five major circulation patterns formed by the currents on this map are the world’s five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.
What is the biggest ocean currents in the world?
Notorious among sailors for its strength and the rough seas it creates, the Antarctic Circumpolar Current (ACC) is the largest wind-driven current on Earth and the only ocean current to travel all the way around the planet. Now, researchers have found that the current transports 30% more water than previously thought.
Why is ocean water always saline?
The two ions that are present most often in seawater are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand.
What is the ocean current called?
Thermohaline circulation, also known as the ocean’s conveyor belt, refers to the deep ocean density-driven ocean basin currents. These currents, which flow under the surface of the ocean and are thus hidden from immediate detection, are called submarine rivers.
Why is Alaska current warm?
A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water. … Upon contact, the drift splits sending a current of warm water poleward (the Alaska Current) and current of cold water Equatorward (the California Current).
Which climate zone is the hottest?
A: Tropical.
In this hot and humid zone, the average temperatures are greater than 64°F (18°C) year-round and there is more than 59 inches of precipitation each year.
Why is the West coast warmer than the east?
Sunlight has a greater area and depth for dispersion than land. The water at the surface is warmer than the water at greater depths. The mountains that line the coastline have an effect on both the East and the West. The water over the oceans is relatively warm.
What is the meaning of La Nina?
La Niña means Little Girl in Spanish. La Niña is also sometimes called El Viejo, anti-El Niño, or simply « a cold event. » La Niña has the opposite effect of El Niño. … During a La Niña year, winter temperatures are warmer than normal in the South and cooler than normal in the North.

Is the Norwegian current warm or cold?
An important aspect of the Norwegian Current is its effect on the ice cover in the Barents Sea. Compared with the cold and fresh Arctic water, the waters of the Norwegian Current are relatively warm and saline.
What are the 5 major ocean currents?
Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The five major circulation patterns formed by the currents on this map are the world’s five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.
Is Brazil current fast or slow?
It is a very deep, cold, and relatively slow current, but it carries a vast mass of water, about twice the volume of the Gulf Stream.
What current is used in Brazil?
Most federative units (about 60 per cent of all Brazilian households) use 127 V electricity, but some other – mainly northeastern – states are on 220 V. Even within some states themselves, the voltage may differ.
Why is the Brazil current warm?
The Brazil current is the western boundary current of the South Atlantic subtropical gyre. It transports warm water polewards. Near 22 S, the Brazil current splits; one component flows eastward and the other component hugs the coast and flows toward the southwest and interacts with the colder Malvinas Current.
What are the 2 types of ocean currents?
There are two main types of ocean currents: currents driven mainly by wind and currents mainly driven by density differences. Density depends on temperature and salinity of the water. Cold and salty water is dense and will sink. Warm and less salty water will float.
Which ocean current is the strongest and fastest ocean current in the world?
Gulf Stream Velocity. 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. In both sections the Gulf Stream is flowing into the page.
