Regarding vorticity,it is true that
A)relative vorticity is always conserved.
B)counterclockwise rotation in the Northern Hemisphere has positive vorticity.
C)Earth vorticity decreases with latitude.
D)vorticity changes in the upper troposphere do not affect surface pressures.

Question

Quizplus · Accepted Answer

In the Northern Hemisphere, counterclockwise rotation has positive vorticity, while in the Southern Hemisphere, clockwise rotation has positive vorticity. Option A is incorrect because relative vorticity can change due to changes in wind, temperature, or pressure. Option C is also incorrect because the Earth's vorticity (due to its rotation) is maximum at the equator and increases with latitude, reaching a maximum at the poles. Option D is incorrect because changes in vorticity in the upper troposphere can affect surface pressures through vertical motion and advection.
