3 The wind is caused by the different temperatures (and therefore air pressure differences) around a planet. The wind is caused by the different temperatures (and therefore air pressure differences) around a planet. This is caused by the Sun. This is caused by the Sun. Copyright © 2010 Ryan P. Murphy

5 An important renewable resource.

6 Brings rain – Without wind, the land wouldn’t get the evaporated water from the oceans. Copyright © 2010 Ryan P. Murphy

7 Activity! Draw the globe below. 0 30 N 30 S 60 N 60 S Equator

8 Global Winds (Word Bank) Global Winds (Word Bank) Go back to drawing of globe Go back to drawing of globe - Doldrums - Doldrums - Horse latitudes - Horse latitudes - Trade Winds - Trade Winds - Prevailing Westerlies - Prevailing Westerlies - Polar Easterlies - Polar Easterlies Copyright © 2010 Ryan P. Murphy

9 Doldrums- Areas of no wind, occurs at the equator, air here heats up fast causing low pressure. Copyright © 2010 Ryan P. Murphy

10 Horse Latitudes- Areas of no wind occurs at 30  N + 30, air stops moving toward the poles and sinks. Copyright © 2010 Ryan P. Murphy

11 Horse Latitudes- Areas of no wind occurs at 30  N + 30, air stops moving toward the poles and sinks. Copyright © 2010 Ryan P. Murphy When boats couldn’t find winds they would drop their weight. Often horses.

12 Horse latitudes again. Copyright © 2010 Ryan P. Murphy

13 Trade Winds- Surface winds are blown toward the equator because the horse latitudes produce areas of high pressure. –Coriolis force curves the wind. Copyright © 2010 Ryan P. Murphy

14 Prevailing Westerlies- Winds blowing toward the pole, move from west to east, occurs between 30  + 60  Copyright © 2010 Ryan P. Murphy

16 Polar Easterlies- Cold air sinks and heads toward the equator, Coriolis Effect curves the winds Copyright © 2010 Ryan P. Murphy

18 What is the name of the winds under the boxes below? Copyright © 2010 Ryan P. Murphy

19 The rotation of the earth (which causes the Coriolis Force). The rotation of the earth (which causes the Coriolis Force). Copyright © 2010 Ryan P. Murphy

21 Pressure gradient forces cause the hurricanes to spin opposite of the Coriolis Force. Copyright © 2010 Ryan P. Murphy

22 Pressure gradient forces cause the hurricanes to spin opposite of the Coriolis Force but the Coriolis Force keeps Atlantic forming hurricanes from crossing the equator and sends them NW. Copyright © 2010 Ryan P. Murphy

24 Coriolis Force means that you can’t fly in a straight line on a moving planet. Copyright © 2010 Ryan P. Murphy

27 The Jet Stream: Any of the high-speed, high-altitude air currents that circle the earth in a westerly direction. The Jet Stream: Any of the high-speed, high-altitude air currents that circle the earth in a westerly direction. Copyright © 2010 Ryan P. Murphy

28 Flying times can be significantly shorter going from California to New York than vice versa because of the Jet Stream (100+kph) Copyright © 2010 Ryan P. Murphy
