Winds
global winds, local winds, rainshadow effect
Term | Definition |
---|---|
Global Winds | Large scale winds that blow across the Earth due to convection |
Local Winds | Winds that occur due to the presence water since land and water absorb heat at different rates |
Air Pressure | The force of air molecules due to gravity |
Barometer | Instrument that measures air pressure |
Anemometer | Instrument that measures wind speed |
Coriolis Effect | The curving of air and water due to the shape of the Earth and the rotation of Earth |
Doldrums | Area of little wind at the Equator |
Horse Latitudes | Area of little wind at 30 degrees latitude due to air rising |
Jet Stream | Narrow belts of high speed winds that influence weather |
Trade Winds | Global winds that blow from 30 degrees latitude to the equator. |
Wind | Created by unequal heating of the Earth |
Windward | The wet side of a mountain, usually has forests |
Land breeze | Wind that blows from land to sea, occurring at night since the land has cooled off |
Leeward | Dry side of a mountain, often a desert |
Polar Easterlies | Global winds that blow from the poles to 60 degrees latitude |
Prevailing Westerlies | Global winds that blow from 30 to 60 degrees latitude. |
Rain Shadow Effect | When a mountain creates a barrier to prevailing winds causing one side of the mountain to be wet, and the other side dry (the dry side is said to be in the "shadow" of the rain. |
Sea Breeze | Wind that blows from sea to land; occurs during the day when the land heats up faster than the water. |
