PRESENTATION OUTLINE
1.
THE MOVEMENT OF AIR
Air moves because of density differences from uneven heat
Sun warms the earth causing air circulation
Rising and sinking air forms convection cells
Convection cells create high and low pressure belts
Coriolis Effect: is the curving of a moving object as result of Earth's rotation

GLOBAL WINDS
Pressure belts and Coriolis effect produce global winds
3 major winds systems: easterlies, westerlies, and trade winds
Jet Stream - bands of high speed winds in the upper troposphere

LOCAL WINDS
Land and water absorb and release energy differently
Resulting in local air pressure differences
Which cause sea, land, mountain and valley breezes
