1. Winds are initiated by what?
E. The pressure gradient
2. The Coriolis effect is caused by what?
C. The rotation of the Earth
3. Because of the Coriolis effect, winds and other moving fluids are deflected to which direction in the Southern Hemisphere?
C. Left
4. In the absence of friction, the combined effect of the pressure gradient and the Coriolis effect would produce what kind of winds?
C. Winds that flow parallel to the isobars
5. What does this sketch of wind flow show?
B. A low pressure center in the Southern Hemisphere, in the friction layer
6. Which of the following statements is true for a high pressure center?
A. A high pressure center is an anticyclone.
7. What does this sketch of wind flow show?
D. A high pressure center in the Southern Hemisphere, above the friction layer
8. In the Northern Hemisphere, which of the following statements would be true of the wind pattern around a low pressure cell on the surface?
A. It would be convergent, with winds moving counterclockwise.
9. Warm temperatures or air converging and rising from the surface are most likely to produce what kind of pressure at the surface?
B. Low
10. Cold temperatures or air subsiding from above are most likely to produce what kind of pressure at the surface?
A. High
