Answer 2

Answer:

• North Equatorial Current (Warm) : Normally, the north equatorial current is formed between the equator and 10° N latitude. This current is generated because of upwelling of cold water near the west coast of Africa. This warm current is also pushed westward by the cold Canary current. On an average, the north equatorial warm current flows from east to west but this saline current is deflected northward when it crosses the mid-Atlantic Ridge near 15°N latitude.

• South Equatorial Current( Warm) - South equatorial current flows from the western coast of Africa to the eastern coast of South America between the equator and 20° S latitude. This current is more constant, stronger and of greater extent than the north equatorial current. In fact, this current is the continuation of the Benguela current.

• Counter-Equatorial Current (Warm): The counter equatorial current flows from west to east in between the westward flowing strong north and south equatorial currents. This currents is less developed in the west due to stress of trade winds. In fact, the counter current mines with the equatorial currents in the west but it is more developed in the east where it is known as the Guinea Stream

• Gulf Stream (Warm): The Gulf Stream is a system of several currents moving in north-easterly direction. This current sys­tem originates in the Gulf of Mexico around 20 N latitude and moves in north easterly direction along the eastern coast of North America and reaches the western coasts of Europe near 70° N latitude.

• Canary Current (Cold): The Canary current, a cold current, flows along the western coast of North Africa between Maderia and Cape Verde. In fact, this current is the continuation of North Atlantic Drift which turns southward near the Spanish coast and flows to the south along the Coast of Canaries Island. The average velocity of this current is 8 to 30 nautical miles per day. This current brings cold water of the high latitudes to the warm water of the low latitudes and finally merges with the north equatorial current. The Canary cold current ameliorates the otherwise hot weather conditions of the western coasts of North Africa.

• Labrador Current (Cold):

The Labrador Current, an example of cold cur­rent, originates in the Baffin Bay and Davis Strait and after flowing through the coastal waters of Newfound­land and Grand Bank merges with the Gulf Stream around 50°W longitude. The flow discharge rate of the current is 7.5 million m3 of water per second. This current brings with it a large number of big icebergs as far south as Newfoundland and Grand Bank. These iceberges present effective hindrances in the oceanic navigation. Dense fogs are also produced due to the convergence of the Labrador cold current and the Gulf Stream near Newfoundland.

• Brazil Current (Warm):

The Brazil current is characterized by high temperature and high salinity. This current is gener­ated because of the bifurcation of the south equatorial current because of obstruction of the Brazilean coast near Sun Rock. The northern branch flows northward and merges with the north equatorial current while the southern branch known as the Brazil current flows southward along the east coast of South America upto 40°S latitude.

Thereafter it is deflected eastward due to the deflective force of the rotation of the earth and flows in easterly direction under the influence of the westerlies. The Falkland cold current coming from the south merges with the Brazil current near 40°S lati­tude.

• Falkland Current (Cold):

The cold waters of the Antarctic Sea flows in the form of Falkland cold current from south to north along the eastern coast of South America upto Argentina. This current becomes most extensive and developed near 30⁰S latitude. This current also brings numerous icebergs from the Antarctic area to the South American coast.

• South Atlantic Drift (Cold):

The eastward continuation of the Brazil current is called South Atlantic Drift. This current is originated because of the deflection of the Brazil warm current eastward at 40° S latitude due to the deflective force of the rotation of the earth. The South Atlantic Drift, thus, flows eastward under the influence of the westerlies. This current is also known as the Westerlies Drift or the Antarctic Drift.

• Benguela Current (Cold):

The Benguela current, a cold current, flows from south to north along the western coast of South Africa. In fact, the South Atlantic Drift turns north­ward due to obstruction caused by the southern tip of Africa. Further northward, this current merges with the South Equatorial Current.
