Breezing Through The Wind

By: Jonathan Strong

General Information on Wind

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

The Greater the difference, the Faster the wind moves.

Information On Local Winds

Generally move short distances and can blow in any direction

Caused by geographic features that produce temperature differences


Low pressure is created over the land during the night and high pressure over land due to uneven heating.


High pressure is created over the ocean during the day and low pressure over land due to uneven heating.

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.

Temperature differences between the equator and the poles produce giant convention currents in the atmosphere.

Polar Easterlies

Wind belts that extend from the poles to 60° latitude.

Formed from cold sinking air moving from the poles creating cold temperatures.


Wind belts found between 30° and 60° latitude.

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

Trade Winds

Winds that blow from 30° almost to the equator.

Called the trade winds because of their use by early sailors.


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.
