← GeographyWhich mechanism disrupts the Hadley cell circulation pattern during El Niño events?
A)Intensified Coriolis force deflections
B)Anomalous warming of the equatorial Pacific✓
C)Strengthened polar vortex oscillations
D)Increased global volcanic aerosols
💡 Explanation
When the equatorial Pacific experiences anomalous warming during El Niño, the Walker circulation weakens because the normal pressure gradients reverse, inhibiting convective uplift. Therefore, anomolous warming disrupts Hadley cell patterns, rather than strengthened Coriolis force, polar vortex or aerosol changes, which have different effects.
