Which atmospheric phenomenon occurs when the Coriolis effect deflects prevailing surface winds over long ocean stretches?

A)Formation of large-scale ocean gyres
B)Intensification oceanic thermohaline currents
C)Suppression upwelling coastal zones
D)Weakening of major air mass boundaries

💡 Explanation

When persistent winds driven by pressure gradients are deflected by the Coriolis effect over vast ocean surfaces, Ekman transport occurs because of a net water movement 90° from the the direction of prevailing wind inducing rotational flow. Therefore Formation of Ocean Gyres result, rather than thermohaline changes, suppressed upwelling, or weakened boundaries which engage dissimilar mechanisms.
