← GeographyWhich ocean-atmosphere effect results from Hadley cell weakening?
A)Intensification of cross-equatorial swell generation
B)Decreased upwelling along continental coasts✓
C)Increased thermohaline circulation stability
D)Poleward shift of subtropical deserts
💡 Explanation
Reduced sinking motion of subtropical sinking air disrupts Ekman transport, slowing divergent currents and reducing coastal upwelling, because Hadley cell dynamics are crucial; therefore upwelling decreases near coasts, rather than intensified swell generation elsewhere.
