1. Chapter 22 Section 3 Review Page 564 #’s 1-6

2. 1 • Describe the pattern of air circulation between an area of low pressure and an area of high pressure. • Air moves from regions of high pressure toward regions of low pressure.

3. High pressure and low pressure

4. 2 • Explain how the Coriolis effect affects wind flow. • In the Northern hemisphere, winds curve to the right; in the southern hemisphere, they curve to the left.

5. Coriolis effect on winds

6. 3 • Name and describe Earth’s three global wind belts. • Polar easterlies are prevailing winds that blow from east to west between 60o and 90o latitude in both hemispheres. • The westerlies are winds that blow from the southwest in the Northern Hemisphere and from the northwest in the southern Hemisphere in the belts between 30o and 60o latitude.

7. 3 continued • Name and describe Earth’s three global wind belts. • The trade winds are prevailing winds that blow from the northeast from 30o N to the equator and from the southeast from 30o S to the equator.

8. Earth’s three global wind belts

9. 4 • Summarize the importance of the jet streams. • Jet streams are narrow bands of high-speed winds that blow in the upper troposphere and lower stratosphere. • They are important because they can affect the paths of storms and airline routes.

11. 5 • Identify two factors that create local wind patterns. • Temperature differences between land and sea and between mountains and valleys influence local wind patterns.

12. Temperature differences between land and sea

13. 6 • Determine whether wind moving south form the equator will curve eastward or westward because of the Coriolis effect. • Wind moving southward from the equator will curve to the east because of the Coriolis effect.
