1. Climate

2. Climate
Average weather conditions at a location over a long period of time. Climate is the pattern of weather over a long period of time.
Determined by average temperature and amount of precipitation.
Climate is what you expect, weather is what you get!

3. 4 Factors Affecting Climate (Temperature & Precipitation)

4. Why do the following locations have different climates?
Brazil, South America
Russia

5. Latitude (uneven heating from equator to poles)

6. Why do the following locations have different climates?
Tignes, France

7. Elevation (temperature drops the higher your elevation)

8. Why do the following locations have different climates?
Portland Minneapolis

9. 3. Distance from Large Bodies of Water (oceans, seas, large lakes)
oceans hold their heat longer creating mild coastal climates

10. Newfoundland
Scilly Isles

11. 4. Ocean Currents Warm-water currents warm coastal climates
Cold-water currents cool coastal climates.

12. (Temperature and Precipitation)
Climate Zones
(Temperature and Precipitation)

13. Climate Zones (Temperature & Precipitation)
Tropical: Temps? Precip?
Desert: Temps? Precip?
Temperate: Temps? Precip?
Polar: Temps? Precip?

14. FOUR Basic Climate Zones (Based on Temperature & Precipitation)
Tropical – (0-25 degrees latitude) warm temps year round & high levels of precipitation
Desert (Arid) – (25-35 degrees latitude) hot temps during day & low levels of precipitation
Temperate – (35-60 degrees latitude) seasonal temps & moderate/seasonal precipitation
Polar – (60-90 degrees latitude) cold temps year round & low levels of precipitation

16. Koppen’s Climate Zone Classification

17. Koppen’s Climate Zone Classifications

18. Climate Change

19. El Nino (impact on global climate for 1-2 yrs)
Dry conditions in the western Pacific (Australia & Indonesia)
Heavy rainfall in South America (Peru) & Southern U.S.
Mild winter temps in Northern U.S.

20. Volcanic Eruption (1-100s of yrs depending on size of eruption)
Volcanic dust & sulfur dioxide blocks solar energy

21. Meteor Impact (similar to volcanic eruptions)

22. Global Warming (human impact on atmosphere, could be 100s of yrs)

23. Ice Ages (1000s of yrs)

24. Ice Age (from ocean current “conveyor belt”)

25. Continental Drift (millions of yrs)
