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.

• Which flow pattern arises when wind-driven surface currents converge toward the center of an ocean gyre?
• Which flooding outcome occurs when frequent deposition overloads fans at mountain fronts?
• Which outcome occurs when lithospheric plates subduct irregularly?
• Which consequence results when sediment accretion ceases along coastlines?
• Near strike-slip plate boundaries, which outcome reduces displacement during earthquakes?
