Wild, Wonderous, Working, Winds

Definition of wind

Wind is when the there is movement in the air caused by unequal heating.

Land and Sea Breezes

land and sea breezes are local winds that are caused by unequal heating on the earth's surface within a small area. A land breeze is when cool air rises up towards the sea, and a sea breeze is when cool air moves beneath warm air towards the sea.

Global Winds

The combination of pressure belts and the coriolis effect cause global winds. The global wind apear in a large area. If the earth doesn't rotate then global winds blow from the north and south poles. The movement of air betweenm the equator and the poles produce global winds.

Large Convection Currents

When warm air gets above the earth surface and instead of staying near the equator it flows away and moves toward the north and south poles.

When warm air rises and creates a low air pressure. When the warm air rises the cool air moves into the area where there is low pressure area, but the cold air is warmed up rapidly.

Jet Streams

A 10 kilometer high wind that go high speeds that go 200-400 kilometers per hour. Jet streams usually blow from west to east and as jet steams travel around Earth, they wander north and south along a wavy path.

Polar Easterlies

Cold air near the north and south pole sinks a flows towards the lower latitudes. The coriolis effect shifts the polar winds to the west creating the polar eastrlies. The polar easterlies and the prevailing westerlies meet at 60° north and 60° south latitudes.

Prevailing Westerlies

In the mid latitudes, between 30° and 60° the north and south winds blow towards the north and south poles that are turned toward the east by the coriolis effect. This happens because the wind blows west to east, it is called the prevailing westerlies.
