What is WInd?

Wind is air moving from areas of high pressure to areas of low pressure. Wind is moving air. Two factors are used to specify wind: speed and direction.

Wind is caused by the uneven heating of Earth's surface by the sun. Warm air rises and cooler air moves in replacing the warmer air. The movement of this air is wind.

Local Winds

Local winds are one of a number of winds that are influenced predominantly by the topographic features of a small region.

Land Breezes

Land breezes blow from the land to the ocean. As warm air over the ocean rises it is replaced by cooler air blowing in from the land.

Sea Breezes

Sea breezes blow from the ocean to the land. As warm air over the land rises it is replaced by cooler air blowing in from over the sea.

Global Winds

Global winds travel over large areas. They blow steadily from specific directions over long distances.

A series of wind belts circle the Earth. Between them are calm areas where wind is rising and falling. If Earth didn't rotate global winds would blow in a straight line. The way the winds curve is called the Coriolis effect.

Doldrums

The doldrums are part of global winds. They are a very low pressure area along the equator where prevailing winds are the calmest. This low pressure is caused by the constant heating by the sun.

Horse Latitudes

The Horse Latitudes are areas of falling air which are very calm.

Jet Stream

The Jet stream is a fast flowing narrow band of air currents found in the atmosphere. The main jet streams are found in the troposphere.
