Winds

General information on winds

Wind definition- Wind is the sideways movement of air. The air always moves from an area of high pressure to an area of low pressure

Wind is caused by the uneven heating of the Earth's surface

Information on local winds

Local wind definition:Local winds are winds that blow over a short distance

Local winds are created by the unequal heating of Earth's surface within a small area

Sea breezes blow from an ocean to land

Land breezes blow from land to a body of water

Information on global winds

Global winds are winds that blow steadily over long distances

Global winds are created by the unequal heating of the Earth's surface, for example the sun shines directly over. The uneven heating at the poles create giant convection currents making global winds

Doldrums- The doldrums are local winds that lie at the equator (0 degrees) and it is a calm area where warm air rises

Jet streams-band of strong winds in the upper troposphere

Trade Winds- very strong winds also sailors use them for trade

Prevailing westerlies- Lie between 30 and 60 degrees north and south latitude
