<p> Chapter 19 Reading Guide The Atmosphere in Motion</p><p>19.1: Air Pressure and Wind</p><p>Air Pressure Elevation Temperature Humidity</p><p>Increasing Elevation leads Decreasing temperature Increasing humidity leads to to decreasing air pressure leads to increasing air decreasing air pressure pressure</p><p>1. Define air pressure. Then describe the likely weather in both high and low-pressure conditions.</p><p>Air pressure: </p><p>In high-pressure conditions:</p><p>In low-pressure conditions: </p><p>2. Name and describe a way to measure air pressure.</p><p>19.2: Factors Affecting Winds</p><p>List the ways that the Coriolis effect and friction affect wind.</p><p>Coriolis Effect Friction Lessens impact of Coriolis effect, allowing winds to blow on truer course Greater effect over flat land than hilly land</p><p>Greatest effect over the ocean</p><p>Effect on winds decreases with elevation 1. Define the jet stream and explain the effect friction has on it.</p><p>19.3: Global Wind Patterns</p><p>1.Explain how warm and cool air circulate through the cells of the three-celled circulation model. Discuss how the Coriolis effect changes the direction of the air as it circulates.</p><p>Global wind patterns create somewhat predictable conditions at different places on Earth. List the likely conditions in each latitude zone.</p><p>Air Temperature Air Pressure Surface wind direction and strength 1. 0 - 30 Low</p><p>2. 30- 60 Hot Little wind, westerly</p><p>3. 60 - 90 Low</p><p>4. 90 Coldest Steady wind, easterly</p><p>19.4 Continental and Local Winds</p><p>Under each label, describe the change of direction and temperature of the air as time passes.</p><p>Sea Breeze Circulation Land-Breeze Circulation</p><p>Describe monsoon winds and explain how the effects of both the seasons and the continents combine to create these winds.</p>
