- Local wind
- winds that blow over short distances and affect local weather.
- wind vane
- measures wind direction
- Global winds
- wind patterns, caused by the Coriolis effect and travel the earth.
- trade winds
- Steady winds that occur between the equator and 30 degrees latitude(north & south).
- Wind
- horizontal movement of air from an area of high pressure to an area of lower pressure.
- Maritime Tropical Air Mass
- Has warm temperatures and lots of moisture. It orginates over warm waters.
- Continental Polar air mass
- Created by long winter nights and strong cooling, which make the air cold & unstable.
- polar easterlies
- Winds that blow from northeast to southwest near the north pole and from southeast to northwest near the south pole.
- Latitude
- invisible lines that go side to side around the globe and are the distance north or south of the equator.
- Anemometer
- something that measures wind speed.
- prevailing westerlies
- Winds that blow in he opposite direction from trade winds(towards the poles) and are between 30 & 60 degrees latitude(north & south).
- Jet stream
- bands of high speed winds in the upper troposphere.
- Land breeze
- At night, air moves toward the water as the land cools more rapidlly than the water.
- Corioles effect
- the rotation of the Earth causes moving air and water to change direction to the right north of the equator and left south of the equator. Winds appear to be curving.
- air mass
- A large body of air that has similar temperature and moisture properties throughout.
- Sea breeze
- A convection current blows wind from the cooler sea toward warmer land during the day.
- doldrums
- Calm areas near the equator with little wind and they cause daily rain patterns.
