The world amazing winds

General Information on Wind

Wind is the movement of air caused by differences in air pressure

wind is caused by the difference of air pressure

Information on Local Winds

Generally move short distances and can blow in any direction

Caused by geographic features that produce temperature differences



Air moves from the ocean to the land creating a sea breeze this blows towards the land during the day


This causes wind to move from the land to the ocean creating a land breeze it blows towards the sea at night

Information on Global Winds

The combination of pressure belts and the Coriolis Effect cause global winds

These are polar easterlies, prevailing westerlies, and trade winds these are the winds between the poles and equator the one blows at the wind is the uneven air pressure so there are convection currents.


horse latitude Occur at about 30° north and south of the equator where the winds are very weak Most deserts on the Earth are located here because of the dry air

trade winds Winds that blow from 30° almost to the equator

Called the trade winds because of their use by early sailors

jet streams The jet streams are narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere Separates warm air from cold air

prevailing westerlies Wind belts found between 30° and 60° latitude

Flow towards the poles from west to east carrying moist air over the United States
