Factors Affecting Climate

2. in Brazil! The tropics always get my direct rays!
L = Latitude
The closer you get to the equator, the hotter it gets =
Gee it's hot
in Brazil! The tropics always get my direct rays!
Low Latitude = high Temp
Middle Latitudes= seasonal temperature
Higher latitudes= lower temperature

3. Tilt of the earth creates the Seasons
June 21, Summer Solstice

4. A = Air Mass Polar air moves towards tropics, tropics move to poles
When two air masses meet= wind, storms, fronts

5. M = Mountain Barrier the Orographic Effect
Blocks air & moisture
windward leeward
Leeward Side
Rain Shadow
Let’s draw this!

6. Windward side of the Cascades
Leeward side of the Cascades
Rain Shadow

7. E = Elevation The higher you go, the colder and drier it gets
Temperature drops 3.5 degrees per 1,000 feet increase!
75 °at bottom
-28°
47° temp at top
3.5° (from formula
x 8 (mt. highth)
28°

8. C = Continental Location- Continentatlity
Location : Center of continent. Not influenced by proximity to water.
Water and land heat and cool at different rates which affects temperature and precipitation.

9. When a place is completely surrounded by
land. (landlocked) and away from water!
St. Louis is hotter than Houston in the Summer
Experiment: Bucket of sand vs. a bucket of water. Which one will heat up quicker and will have a higher temperature?

10. O = Ocean Currents Gulf Stream Warm water moves away from the equator
Cold water moves away from the poles
North Atlantic Drift
Gulf Stream

11. W = Winds – pressure and prevailing winds
High pressure is heavy, cold air
Low pressure is light, warm air.
Heat rises- cool falls convection!!
Prevailing winds- consistent pressures and winds

13. S = Storms When air masses hit they create storms.
The type of storm depends on the type of air mass.
Tornadoes - Fujita-Pearson scale-
F0= 40-70mph F5= around 300mph

14. S- Storms. Seasonal storms will greatly influence the climate of a place.
Hurricanes- Atlantic O, Gulf of Mexico
Typhoons- Pacific O.
Cyclones- Indian O.
Monsoons- the seasonal shift in winds that affect South Asia.

15. Arid Climate

Fargo, North Dakota
Paris, France
Calcutta, India
