Which thermocline response intensifies due to Niño events?

💡 Explanation

An intensified Walker circulation causes increased upwelling decline in the Eastern Pacific via suppressed thermocline tilting during El Niño. This is because weaker trade winds reduce surface water displacement, therefore the absence of upwelling reduces nutrient availability, rather than increasing deep water formation in polar regions.

• Which risk increases in coastal regions with alluvial plains when storm surge exceeds natural levee height?
• Which risk increases downwind when deforestation alters a regional albedo?
• Which depositional pattern develops when a mountain stream abruptly enters a broad, dry valley?
• Which outcome occurs when storm surge enhances longshore drift?
• Which pattern results from Ekman transport deflecting surface currents?
• Which geographic feature results when prevailing wind encounters an obstacle, reducing its velocity and causing increased alluvial deposition?
