← GeographyWhich hydrologic consequence results from El Niño events?
A)Intensified coastal upwelling subsidence
B)Increased strength of gyre currents
C)Weakened thermohaline circulation downwelling
D)Extreme shifts in regional precipitation✓
💡 Explanation
El Niño disrupts normal weather patterns; the Walker circulation weakens. This disruption alters global atmospheric pressure; therefore, precipitation deviates dramatically from historical norms, rather than consistent deep water formation or wind patterns.
