During an El Niño event, where does warm water primarily accumulate in the Pacific Ocean?
A
In the central Arctic Ocean
B
Along the coast of Japan (northwestern Pacific)
C
Near Australia and Indonesia (western Pacific)
D
Along the western coast of South America (eastern Pacific)
Verified step by step guidance1
Understand the concept of El Niño: El Niño is a climate phenomenon characterized by the warming of surface waters in the eastern Pacific Ocean, disrupting normal weather patterns globally.
Identify the normal conditions in the Pacific Ocean: Typically, trade winds push warm surface water westward toward Australia and Indonesia, while cooler water upwells along the western coast of South America.
Recognize the changes during an El Niño event: During El Niño, the trade winds weaken or reverse, causing warm water to accumulate along the western coast of South America (eastern Pacific) instead of being pushed westward.
Analyze the options provided: Eliminate incorrect choices by understanding that the warming occurs in the eastern Pacific, not the Arctic Ocean, northwestern Pacific, or western Pacific near Australia and Indonesia.
Conclude that the correct answer is 'Along the western coast of South America (eastern Pacific)' based on the accumulation of warm water during El Niño events.
