← GeographyWhich oceanic shift results when subtropical anticyclones intensify?
A)Enhanced coastal upwelling shear forces✓
B)Increased sea ice formation increases
C)Weakened thermohaline convection occurs
D)Reduced chlorophyll production expands
💡 Explanation
Intensified anticyclones create stronger, more persistent winds, resulting in enhanced Ekman transport. This causes greater divergence of surface waters, leading to intensified coastal upwelling because nearshore areas draw water from the deep ocean, rather than experiencing downwelling.
