1 Large Scale Patterns of Climatic Variations Amanda Rosenberger Photo :

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

3 Photo:

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 moves north and south Air warms up and collects moisture

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

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 Photo:

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
