Which outcome occurs during ENSO when normal trade winds weaken?

💡 Explanation

Weakening trade winds during ENSO reduces the normal upwelling because Ekman transport is diminished near the South American coast; therefore fewer nutrients reach surface waters, rather than increased fog which demands cold upwelling waters maintaining atmospheric stability.
