| wind | movement of air from an area of high pressure to an area of lower pressure |
| local winds | the two types are: sea (water) breeze and land breeze |
| sea breeze | flow of air from the sea to the land, sometimes called a water breeze |
| land breeze | flow of air from the land to the sea |
| global winds | the four types are: doldrums, tradewinds, prevailing westerlies, and polar easterlies |
| doldrums | light, calm global winds found in a narrow belt above the equator |
| trade winds | warm, calm, steady global winds located between 0 and 30 degrees latitude in both hemispheres |
| prevailing westerlies | strong global winds that travel from west to east and are located between 30 and 60 degrees latitude in both hemispheres |
| polar easterlies | cold global winds that travel east to west between 60 and 90 degrees latitude in both hemispheres; these change the weather in the USA |
| horse latitudes | the place where sailors used to get stuck because there was too little wind (30 degrees latitude) |
| Coriolis Effect | shift in wind direction caused by the rotation of the Earth on its axis |
| Anemometer | instrument used to measure wind speed |
| Wind Vane | Instrument used to tell the direction the wind is blowing |
| Tornado | violent, unpredictable whirlwind storm, which has the strongest winds on Earth |
| Hurricane | Giant wind storms, which begin in warm water, which bring strong rain and wind |
