Winds

Stack #178143

QuestionAnswer
winds are formed by this movement of air from one place to another.
two types of winds local and global
Local winds blow from any direction and usually cover short distance
Global winds blow from specific direction and longer distances than the local winds
Local and Global winds are caused by differences in air pressure due to unequal heating o the atmosphere
sea breeze the flow of air from the sea to land
land breeze a flow of air from land to sea. It can also be called off-shore breeze
monsoon a major land and sea breeze, seasonal wind, very common in Asia
large global wind systems an unequal heating of the Earth's surface
At the equator the warm air rises
At the poles the cooler air sinks
Global pattern of air circulation at the equator warm air rises and moves to the at the poles the cool air sinks and moves to the equator.
Coriolis Effect the apparent shift in the path of any fluid or object moving above the surface of the Earth due to the rotation of the Earth.
Doldrum at the equator surface winds are calm
trade winds the air moving back toward the equator forms a belt of warm, steady winds
horse latitudes the latitudes 30 degrees north and south of the equator
northeast trades in the northern hemisphere, the Coriolis effect deflects the trade winds to the right
southeast trades In the southern hemisphere the trade winds are deflected to the left
Prevailing Westerlies In both hemispheres the winds appear to travel from west to east, they are strong winds
Polar Westerlies The band of cold air is deflected west by the Corislis effect, winds travel from east to west, cold weak winds
Jet stream the wind is a narrow belt of strong, highspeed, high pressure air, take great detours north and south
Airplane pilots use the jet stream to increase speed and save fuel when flying west to east
Wind vane to determine the direction of the wind on the Earth's surface, points into the wind
anemometer is used to measure wind speed
