Briefly describe the effects of severe El Niño events
What will be an ideal response?
Severe El Niño events can be associated with ecological and economic disaster. In areas that normally experience upwelling, specifically the tropical eastern Pacific, a strong El Niño event brings warm water into an area and may even result in downwelling instead of upwelling. Marine life dependent upon upwelling of nutrient-rich waters is adversely affected. Areas normally experiencing arid conditions may receive above-normal precipitation, while normally wet areas may experience the opposite effect.
