Air MovementWhat is wind?
How does the Coriolis Effect play a role in air movement?
What are the doldrums?
Air Movement
Wind
Moves from areas of high pressure to areas of low pressure
Caused by uneven heating of the atmosphere
Causes temperature and pressure differences
Air Movement
Coriolis Effect
The effect of Earth’s rotation on the movement of air masses
Changes the direction of air flow
Northern Hemisphere – currents deflect right
Southern Hemisphere – currents deflect left
Air Movement
Flowing of air caused by uneven heating of Earth
The Coriolis Effect
The air above the equator rises
Low density, low pressure
Trade Winds
Steady winds between the equator and 30 degrees north or south
Jet Stream
Narrow belt of strong winds blowing from west to east in each hemisphere
Location: top of the troposphere
97 to 185 km/hr
The land cools more rapidly than the water
Breezes Caused By: the land heating and cooling more quickly than water
