← GeographyWhich effect occurs when air masses move poleward from subtropical high-pressure zones, deflected by the Coriolis force?
A)Formation of trade winds towards the equator
B)Creation of prevailing westerlies in mid-latitudes✓
C)Development of polar easterlies at high latitudes
D)Intensification of tropical cyclone rotation
💡 Explanation
When air masses move poleward from subtropical highs, the Coriolis force deflects them eastward because it causes moving objects to curve relative to the Earth's rotating surface, producing prevailing westerlies in the mid-latitudes. Therefore, prevailing westerlies develop, rather than trade winds, polar easterlies, or intensified cyclone rotation, which involve different pressure gradients and locations.
