Which effect results when approaching air masses deflect in the northern hemisphere due to planetary vorticity?

A)Westward prevailing wind direction
B)Eastward prevailing wind direction
C)Increased tropospheric temperature
D)Decreased stratospheric ozone

💡 Explanation

When approaching air masses are influenced by planetary vorticity, the Coriolis effect deflects them to the right in the northern hemisphere, because of the Earth's rotation, leading to a westward direction. Therefore westward prevailing winds result, rather than eastward winds, warming, or ozone depletion which have independent mechanisms.
