General Information About Wind

Wind is the movement of air. Wind is caused by differences in air pressure. When the high air pressure collides with low air pressure, it creates wind. The greater the difference, the faster the wind moves. There are 11 big winds including PRESSURE BELTS, GLOBAL WINDS, Polar Easterlies, PREVAILING WESTERLIES, TRADE WINDS, DOLDRUMS, HORSE LATITUDES, JET STREAMs, LOCAL WINDS, LAND BREEZES and SEA BREEZES. Each wind has a different type of ability and all the information about these furious winds will be told below.

Air Pressure

Differences in air pressure are caused by the uneven heating of Earth. Uneven heating produces pressure belts which occur every 30° latitude

Pressure Belts

As warm air rises at the equator and moves toward the poles, it cools. As it cools, some of the air sinks around 30° north and south of the equator. At the poles, cold air sinks and moves towards the equator. Around 60° north and south, the air begins to heat up and rise

Global Winds

The combination of pressure belts and the Coriolis Effect cause global winds. These are polar easterlies, prevailing westerlies, and trade winds

Types of Global Winds

Definition of Local Winds

Local winds are caused by geographic features that produce temperature differences

Descriptions About How Local Winds Are Created

Local winds Generally move short distances and can blow in any direction.

Sea Breezes

  • High pressure is created over the ocean during the day and low pressure over land due to uneven heating. Air moves from the ocean to the land creating a sea breeze.

Land Breezes

  • Low pressure is over the ocean during the night and high pressure over the land due to uneven heating. This causes the wind to move from the land to the ocean creating a land breeze.

Horse Latitudes

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.

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

Big image

Polar Easterlies

Wind belts that extend from the poles to 60° latitude. Formed from cold sinking air moving from the poles creating cold temperatures

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
