Earth vorticity
A)is greatest at the Equator.
B)does not affect absolute vorticity.
C)is a function of latitude.
D)is vorticity relative to the earth's surface.

Question

Quizplus · Accepted Answer

Earth vorticity is a function of latitude, which means it varies with the distance from the Equator. It is caused by the rotation of the earth on its axis and is defined as the component of the local rotation rate of the atmosphere that is perpendicular to the surface of the earth. Therefore, it is vorticity relative to the earth's surface. Option A is incorrect because the vorticity is actually minimal at the Equator due to the lack of Coriolis force. Option B is incorrect as Earth vorticity is a significant contributor to the absolute vorticity of the atmosphere.
