Air Circulation. Air-Sea Interface The atmosphere and the ocean act as one independent system. Solar energy causes winds. Atmospheric winds create most.

• At the poles (areas which receive less solar radiation), the air is cold and descends towards the equator through the lower layers of the atmosphere.

Global Winds Winds that blow over a long distance Caused by movement of air between equator and poles

The Coriolis Effect Deflection of winds due to rotation of the Earth Northern Hemisphere: to the right Southern Hemisphere: to the left

Latitude

Latitude The distance from the equator, measured in degrees. 30 N / S (Tropic of Cancer/Capricorn) 60 N / S

Global Wind Belts Trade Winds Prevailing Westerly Polar Easterlies

Trade Winds Between the equator and 30 N & between the equator and 30 S Winds that sailors relied on for trade.

Prevailing Westerlies Between 30 & 60 N and between 30 & 60 S Play an important role in the weather of the United States.

Polar Easterlies Between 60 & 90 N and between 60 & 90 S. Affects weather changes in the United States.
