IT'S ALL ABOUT WIND
What I learned about wind
What is wind?
Wind is the movement of air caused by differences in air pressure.The greater the difference, the faster the wind moves.
What is a Local Wind?
Local Winds
Local Winds generally move short distances and can blow in any direction.Also, their caused by geographic features that produce temperature differences.
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 occurs over the ocean during the night and high pressure over land due to
the uneven heating of earth.This causes wind to move from the land to the ocean creating
a land breeze
What is a Global Wind?
Global Wind
Global Winds
The combination of pressure belts and the Coriolis effect cause global winds.They are polar easterlies, prevailing westerlies, and trade winds
Polar Easterlies
Wind belts that extend from the poles to 60° latitude.It's formed from cold sinking air moving from the poles creating cold temperatures.
Prevailing Westerlies
Wind belts found between 30° and 60° latitude.It flows 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.It's called the trade winds because of their use by early sailors.
More from Global Wind
Doldrums
Located along the equator where no winds blow because the warm rising air creates and area of low pressure
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.
