1 Chapter 22 Section 3 Handout Atmospheric Circulation

2 1 What causes the movement of air worldwide? –Pressure differences in the atmosphere.

3 2 In what pattern does air near Earth’s surface generally flow? –From the poles toward the equator.

4 6 The circulation of the atmosphere and of the oceans is affected by –the rotation of the Earth on its axis.

5 7 Earth’s rotation causes its diameter to be –greatest through the equator.

6 8 Do points near the equator or points near the poles travel farther and faster in a day? –Points near the equator because each point on Earth makes one complete rotation every day points near the equator travel farther and faster in a day

7 10 The curving of the path of a moving object from an otherwise straight path due to Earth’s rotation is called the __________. –Coriolis effect.

8 11 What impact does the Coriolis effect have on the winds? –Winds that blow from high-pressure areas to low-pressure areas curve as a result of the Coriolis effect.

9 13 In which direction does the Coriolis effect deflect moving objects in the Northern Hemisphere? In the Southern Hemisphere? –Northern Hemisphere: deflected to the right –Southern Hemisphere: deflected to the left –to the left

10 17 What are the three looping patterns of air flow in each hemisphere called? –convection cells

11 19 The prevailing winds that blow from east to west from 30 o latitude to the equator in both hemispheres are called the –trade winds.

12 22 The prevailing winds that blow from west to east through the contiguous United States are the –westerlies.

13 23 What are the prevailing winds that blow from east to west between 60 o and 90 o in both hemispheres? –the polar easterlies

14 Matching 26.doldrums 27.horse latitudes 28.jet streams 29.subtropical jet streams 30.polar jet streams a.narrow bands of winds formed when warm equatorial air meets the cooler air of the middle latitudes b.narrow bands of strong winds that blow in the upper troposphere c.bands of winds formed as a result of density differences between cold polar air and warmer air of the middle latitudes d.subtropical high-pressure zones with weak and variable winds e.a zone of low pressure at the equator where the trade wind systems meet
