The mystery of WIND
By :Nathan Allaire
Definition of Wind
Local Winds
Sea breezes are created by high pressure over the ocean during the day and low pressure over land due to the uneven heating of the earth. Air moves from the ocean to the land creating a sea breeze.
Land breezes are created by low pressure over the ocean during the night and high pressure over the land due to the uneven heating of the earth. This causes wind to move from the land to the ocean creating a land breeze.

Global Winds
Doldrums are areas along the equator where no winds blow because the warm rising air creates an area of low pressure.

Trade Winds, Polar Easterlies, and Jet Streams
Polar Easterlies are wind belts that extend from the poles to 60 degrees latitude. They are formed from cold sinking air moving from the poles creating cold temperatures.
Jet streams are narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere. They separate warm air from cold air.
