General Information About Wind
Differences in air pressure are caused by the uneven heating of Earth. Uneven heating produces pressure belts which occur every 30° latitude
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
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.
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.
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
Winds that blow from 30° almost to the equator. Called the trade winds because of their use by early sailors.
Wind belts found between 30° and 60° latitude. Flow towards the poles from west to east carrying moist air over the United States
Wind belts that extend from the poles to 60° latitude. Formed from cold sinking air moving from the poles creating cold temperatures
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
