3. Factors Affecting Climate
L :Latitude
rays of sun & how it strikes the earth
low latitudes get sun year-round (hot all year)
Middle latitudes (tropics to poles) are temperate
Great temperature shifts
True seasonal changes
High latitudes (Arctic & Antarctic Circles) – Cold all year

4. Factors Affecting Climate
E: Elevation
atmosphere gets thinner
thinner air retains less heat…not as dense as altitude increases

5. Factors Affecting Climate
M: Mountain Barriers
Orographic effect (Rain shadow)
Winds with moisture cool as they move up the mountain and dry out – windward side
Weather patterns weaken or are even stopped as they move across the mountains – leeward side

6. Factors Affecting Climate
P: Proximity (closeness) to water
Water slower to heat than land, so land near water has consistent temperature
Affected by landforms
Tilt of the Earth on its access also play a part

7. Factors Affecting Climate
O: Ocean currents
Rivers flowing in the ocean - Cold and warm streams of water move through oceans (based on earth’s rotation, differences in water temperature, and change in air pressure).
Warm waters flow away from the Equator toward the poles; cold water back toward the Equator
Wind and ocean currents distribute the sun’s heat through CONVECTION (heat rises…)
Global wind patterns work the same way
Direct influence on precipitation
Prevailing Westerlies 
Trade Winds
Doldrums 

8. Factors Affecting Climate
S: Storms
El Nino (boy with the warm heart)
Weather pattern
Seasonal rains in the Americas
Drought in Australia/Asia
Every 2-7 years
La Nina (girl with the cold heart)
Reverse of El Nino
Flooding around and toward India
Drier on the coasts
Certain geographical areas receive more storms than others
Hurricane vs. typhoon
Tornado Alley
