Answer:
During an El Nino event, ocean currents are reversed along the equator and along the west coast of South and Central America.
Explanation:
- During El Niño and Southern Oscillation (ENSO) the atmospheric circulation over the tropical Pacific are changed along with the hindrance in ocean currents.
- The pool of warm surface water normally driven westward by the trade winds now drifts eastward.
- The surface waters in the central and eastern Pacific Ocean become significantly warmer than usual during this event.
- Reduction in the upwelling of cooler, nutrient-rich waters occurs that reverses the ocean currents.
