Characteristics of high- and low-pressure centers in the Northern Hemisphere are listed below. In each case, indicate by H or L whether the statement applies to high- or low-pressure centers. If a statement is valid for both types of centers, place both H and L in the blank space.
1. _____ Winds blow counter-clockwise.
2. _____ Winds spiral inward toward the pressure center.
3. _____ Pressure gradient force points away from the pressure center.
4. _____ Associated with subsidence, dry air and generally clear skies.
5. _____ Vertical motions are downward above the surface pressure center.
6. _____ Wind speeds (in the absence of friction) are slower than geostrophic.
7. _____ Clouds and precipitation generally occur above the surface pressure center.
