← GeographyWhich outcome results when trade winds weaken across gyres?
A)Increased coastal thermocline subsidence occurs
B)Reduced surface water convergence develops✓
C)Enhanced deep water formation strength
D)Intensified high latitude downwelling rises
💡 Explanation
Weakening trade winds reduce Ekman transport and coriolis effect, therefore reduced surface water convergence develops because the pressure gradient shallows, rather than intensified downwelling, due to decline in the geostrophic currents influencing the gyres.
