General Information on Winds

Wind is the movement of air from areas of high pressure to areas of low pressure. Wind is also the sideways movement of air.Winds are caused by the unequal heating of the earth's surface.

Local Winds

A local wind is a wind that happens over a small area, it changes speed and direction a lot. Local winds are created by the unequal heating of earth's surface. A sea breeze happens during the daytime, cooler and heavier air is over the water and moves toward the land and warmer and lighter air is over the land, it blows from the sea to the land. A land breeze happens during the evening, cooler and heavier air is over the land and warmer and lighter air is over the water, it blows from the land to the sea.

Global Winds

Global winds move across the entire planet. Global winds are most likely not to change direction and speed. Global winds are created by the unequal heating of earth's surface over a large area.Doldrums are a calm area where warm air rises.The Coriolis effect is a large convection current that occurs between the equator an the poles. The earth's rotation causes the winds to turn, that means that they do not go straight. In the northern hemisphere global winds turn right and in the southern hemisphere the global winds turn left.Jet stream is a area of very strong winds that travel in the troposphere.Prevailing Westerlies are winds that lie between 30 degrees and 60 degrees north and south latitude and blow from the west and blow toward the east. Polar Easterlies blow cold air away from the poles.
