Which of the following ocean currents is also known as the specific weather current?
1. EI-Nino
2. Benguela
3. Kuroshio
4. Agulhas

Answer 1

Correct Answer - Option 1 : EI-Nino

The correct answer is EI-Nino.

• El Nino is a name given to the periodic development of a warm ocean current along the coast of Peru as a temporary replacement of the cold Peruvian current. Hence it is known as a specific weather current.

• El Nino
  • ​It is the warm phase of the El Nino Southern Oscillation.
  • El Nino is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific.
  • El Nino is accompanied by low air pressure in the eastern Pacific and high air pressure in the western Pacific.
  • La Nina is the cool phase of ENSO.
  • The ENSO cycle, including both La Nina and El Nino, causes global changes in rainfall and temperature.
  • The El Nino Southern Oscillation (ENSO) is the cycle of cold and warm sea surface temperature of the tropical central and eastern Pacific Ocean.
