Wind is The movement of air, from high pressure to low pressure. Copyright © 2010 Ryan P. Murphy
The wind is caused by the different temperatures caused by the sun (and therefore air pressure differences). This is caused by the Sun. Copyright © 2010 Ryan P. Murphy

Temperature differences over the land and over seas. Copyright © 2010 Ryan P. Murphy
Cool air has high pressure Warm air has low pressure
An important renewable resource.
Brings rain – Without wind, the land wouldn’t get the evaporated water from the oceans. Copyright © 2010 Ryan P. Murphy
Wind blowing through your hair feels good / cools you down. Copyright © 2010 Ryan P. Murphy
The wind brings smell. Water, prey items, predators, etc. Copyright © 2010 Ryan P. Murphy
Wind allows a bird to fly with minimal effort. Copyright © 2010 Ryan P. Murphy

Many insects use wind to move / disperse. Copyright © 2010 Ryan P. Murphy
To dry out and also to cool down. Copyright © 2010 Ryan P. Murphy

Global Winds (Word Bank) Go back to drawing of globe - Doldrums - Horse latitudes - Trade Winds - Prevailing Westerlies - Polar Easterlies Copyright © 2010 Ryan P. Murphy
Doldrums- Areas of no wind Doldrums- Areas of no wind , occurs at the equator, air here heats up fast causing low pressure. Copyright © 2010 Ryan P. Murphy
Horse Latitudes- Areas of no wind occurs at 30N + 30, air stops moving toward the poles and sinks. Copyright © 2010 Ryan P. Murphy
Horse Latitudes- Areas of no wind occurs at 30N + 30, air stops moving toward the poles and sinks. When boats couldn’t find winds they would drop their weight. Often horses. Copyright © 2010 Ryan P. Murphy
Horse latitudes again. Copyright © 2010 Ryan P. Murphy
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
Prevailing Westerlies- Winds blowing toward the pole, move from west to east, occurs between 30+ 60 Copyright © 2010 Ryan P. Murphy
Polar Easterlies- Cold air sinks and heads toward the equator, Copyright © 2010 Ryan P. Murphy
Polar Easterlies- Cold air sinks and heads toward the equator, Coriolis Effect curves the winds Copyright © 2010 Ryan P. Murphy

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
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
Jet Stream: Like the ocean current in the movie except in the air. Copyright © 2010 Ryan P. Murphy

Land Breeze (Night): The breeze that blows from the land toward the sea. Copyright © 2010 Ryan P. Murphy
Land Breeze (Night): The breeze that blows from the land toward the sea. High specific heat of water slowly releases stored energy from the day during the night making the water warmer than the land. Copyright © 2010 Ryan P. Murphy

Wind
Wind It’s caused by the different temperatures (and therefore air pressure differences) around a planet.
Wind “Yeh, Wind.”
