Which climate outcome occurs when Walker circulation weakens during intense El Niño events?

💡 Explanation

When Walker circulation weakens, reduced east-to-west pressure gradient causes diminished upwelling because the surface water movement is suppressed by weaker winds. It is linked to El Nino events that develop along the South American coast. Therefore, decreased upwelling results, rather than increased rainfall, strengthened winds, or lower temperatures which all indicate normal or La Nina conditions.
