Question

The oceanic current produced by the irregularly periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean is known as:

Options

  1. A Humboldt current
  2. B El Nino
  3. C Canary current
  4. D Agulhas current
Show Answer

Correct Answer

B El Nino

Model Answer

  • El Nino–Southern Oscillation (ENSO) is an irregularly periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics.
  • The warming phase of the sea temperature is known as El Nino and the cooling phase as La Nina.

Additional Information

Humboldt Current

  • The Humboldt Current is also known as the Peruvian Current.
  • The Current is a cold, low-salinity ocean current that flows north of the western coast of South America.
  • The current extends from southern Chile to northern Peru where upwelled, cold, waters intersect warm tropical waters to form the equatorial front.

Canary Current

  • It is a wind-driven current in North Atlantic Gyre.
  • It is a type of cold current.

Agulhas Current

  • It is a warm current (red) along the east coast of South Africa, and the cold Benguela current (blue) along the west coast.
