Wind Patterns Flashcards
Convection Currents
When gases and liquids rise and sink in a circular pattern
Sea Breeze
When days are sunny, the land heats up faster than the sea. The warm air above the land rises. Cooler air from over the sea moves in to replace it.
Land Breeze
When the sun sets, the land cools off faster than the sea. The warm air above the sea rises. Cooler air from the land moves toward the sea to replace it.
Coriolis Effect
The rotation of the Earth causes objects in the Northern hemisphere to deflect to the right while objects in the Southern Hemisphere are deflected to the left
Jet Stream
A band of very fast moving wind caused by differences in temperature
Trade Winds
Winds that blow toward the equator
Doldrums
A spot near the equator where there are very few winds
Prevailing Winds
Winds that blow away from the equator
Prevailing Westerlies
Winds that blow away from the equator( Blow West to East )
Polar Easterlies
Winds that are found near the poles ( Blow East to West )
The Gulf Stream
An ocean current found in the Atlantic that brings warmer temperatures to the east coast on the U.S
La Niña
A band of cold ocean temperatures that develop off the coast of South America
El Niño
A band of warm ocean temperatures that develop off the coast of South America
