← GeographyWhich thermocline displacement follows reduced trade wind forcing?
A)Decreased coastal upwelling intensity✓
B)Increased phytoplankton bloom duration
C)Enhanced deep ocean carbon sequestration
D)Intensified thermohaline circulation rates
💡 Explanation
Reduced trade winds decrease the wind stress and the Ekman transport off the coast, reducing the upwelling intensity, because this mechanism depends on surface forcing for upwelling. Therefore, upwelling diminishes rather than alternatives which require intensification or different trigger conditions.
