2. Temperature 23 ½° tilt Seasons in Northern Hemisphere
Summer – Earth is tilted toward the sun
Winter – Earth is tilted away from the sun
Spring and Fall – sun is directly overhead the equator
Higher Latitudes – less light from sun= colder climate

4. Atmospheric Circulation
Warm air with moisture rises
Air cools down and moisture is released
Air moves north and south
Air cools more, becomes denser
Cool air sinks back towards surface
Air warms up and collects moisture

5. Atmospheric Circulation
3 air circulation cells on each side of equator

6. Coriolis Effect
Objects appear to move to the right (Northern Hemisphere) and left (Southern Hemisphere)
Winds are named for the direction they begin at

7. Climate Diagrams Developed by Heinrich Walter in 1985
Shows patterns of average variation in temperature, precipitation, wet and dry seasons and portions of the year temperatures are above 0°C
