Wind
BY: Natalie Portonova-Nolan
General Information
- Definition: Wind is the horizontal movement of air of high pressure to an area of lower pressure
- Cause: Differences in air pressure and uneven heating from the sun
- Measured: Anemometer
Doldrums
- Definition: Very clam, not much wind
- Caused by solar radiation from the sun
- Rising air in the Doldrums can cause tropical storms
- Found in the Atlantic and Pacific Oceans
- Almost every hurricane that starts in the Atlantic Ocean started in the Doldrums
Trade Winds
- Definition: A global wind that blows almost all the time
- Found in both the Northern and Southern Hemisphere
- Trade Winds blow from the Southeast
- Between 30 degrees North and South
- Boarder Doldrums to the North and South
Jet Streams
- Definition: A global high-altitude wind
- 6,000-12,000 meters above Earth's surface
- A Jet Stream's location can affect weather where you live
- Jets that fly from east to west get boost in speed from the Jet Stream
- Jets that fly against the Jet Stream are slowed by the winds from it
Local Winds
- Definition: Winds that blow over short distances
- Cause/Created: Unequal heating of Earth's surface in a small area
- Sea Breeze: During the day, warm air rises from the land and the cool air from the sea blows toward the land.
- Land Breeze: At night, the warm air from the ocean rises and the cool air from the land blows out towards the sea.
Global Winds
- Definition: A wind that blows steadily over a long distance
- Cause: Unequal heating of Earth's surface in a large area
- Creation: Parts of the Global Winds are Prevailing Westerlies, Jet Stream, Horse Latitudes, Northeast Trade Winds, and Doldrums. That is all the parts needed for creating the Global Winds.
