2. Heating the Earth Weather is the daily conditions of the atmosphere The factors that interact to cause weather are heat energy, air pressure, winds, and moisture

3. Atmospheric Circulation Coriolis Effect is the tendency for an object to follow a curved path rather than straight due to the rotation of the Earth. Deflected to the right in the Northern hemisphere, left in the Southern Hemisphere Only affects fast moving objects and large objects http://www.nasa.gov/audience/forstudents/brainbites/nonflash/bb_home_corioliseffect.html

4. Global Winds http://www.mhhe.com/biosci/genbio/tlw3/eBridge/Chp29/animations/ch29/global_wind_circulation.swf

5. Trade Winds The winds that flow toward the equator between 0º and 30º Northeast Trade winds in the Northern Hemisphere and Southeast trade winds in the southern Hemisphere

6. Westerlies The winds that flow between 30º to 60º In the Northern Hemisphere these are southwest winds and in the Southern Hemisphere they are northwest winds These are the winds responsible for most of the weather conditions in the US

7. Polar Easterlies These winds blow toward the poles from 60º to 90º In the Northern Hemisphere the winds are southwest winds and in the Southern Hemisphere northwest winds The winds are the strongest where they flow off Antarctic

8. The Doldrums and the Horse Latitudes The area where the Trade winds meet at the equator is know as the Doldrums These are warm low pressure winds The area where the Trade Winds and the westerlies meet is called the Horse Latitudes These winds are subtropical and high pressure winds

9. Jet Stream These winds are narrow bands of fast moving winds that blow in both hemispheres They are found in the upper troposphere and lower stratosphere The Polar jets can blow up to 500km/hr and can change latitude bringing cold air with them The subtropical jet stream do not change in speed or position

10. Local Winds Land and sea breezes Mountain and valley breezes
