1. 2.7Climatic Zones p. 75-81 P. 75 fig. 5.1

2. Describe climatic conditions within selected zones p. 75 6 climate regionsEach has sub-regions 6 climate regionsEach has sub-regions

3. Tropical Climates - Common LOW latitudes (near equator) Between the “Tropics!” Temp. over 18 0 C every day Hence a relatively flat temperature line warm ocean currents & prevailing winds = high precipitation.

4. REALLY ?!?! NOTE: Even though the tropic climates are hot, they are not the hottest climatic region. Why not? With rainfall comes constant cloud cover…which reduces the amount of sunlight reaching the earth. What other effect can cloud cover have on temperatures in this region? HINT: NIGHT…. Muggy!!! Hot, wet air

5. Tropical Wet & Dry - Climate graphs Notice: Relatively flat temperature line Temperature relatively constant & high (19-27 0 C) Wet and dry seasons (monsoons)!!!

6. Tropical Wet - Climate graphs Precipitation in each month is high Temperature constant & high (19-27 0 C) Relatively flat temperature line

7. Dry Climates

8. All Dry climates: < 500mm precipitation annually 10-30 N & S May be continental, leeward side of mountain or influenced by cold ocean current. More evaporation than precipitation Little vegetation Often windy with No cloud cover High daytime temperatures, Low nighttime temperatures Temperatures may vary seasonally

9. Arid - Climate graphs

10. Semi-Arid - Climate graphs

11. REMEMBER!!!! The main factor that characterizes the DRY climate zone is the amount of precipitation – that is, there is not much!

12. Temperate Mild Winter Temperate Mild Winter Mild winter ( above -3 o C). Mild winters usually caused by ocean currents Mid Latitudes (30-60 N & S) Usually near oceans (coastal) Summer temperatures vary

13. Temperate Mild Winter Mediterranean Marine West Coast Subtropical Which is further north??

14. Temperate COLD Winter Locations generally affected by continentality Ex. Reason for colder winters! Mostly inland (continental) Generally the mid Latitudes (30-60 N) Highest precipitation occurs during summer

15. Subarctic Continental Warm Summer Continental Cool Summer Temperate COLD Winter Which is further north??

16. Polar Region  High latitudes  (+60 o latitude)  Near poles Short cool summers Never exceeds 10 o C Coldest, darkest & driest winters Polar Region

17. Ice Cap Tundra Notice how little precipitation occurs. WHY??? Which is further north??

18. Highlands Elevations over 1000 m Colder conditions than the lower lying areas surrounding it. Climates from one highland to another will vary because of latitude, proximity to oceans

19. Patterns of climatic zones Globally speaking where is each climatic zone concentrated? Globally speaking where is each climatic zone concentrated? 1.Tropical ____ 2.Dry ____ 3.Temperate ___ 4.Polar ____ 5.Highland ____

20. Practice Question #2 p. 75 Part a Question #2 p. 75 Part a Georgetown, Guyana Tropical (Tropical wet) Bombay, India Tropical - Monsoonal (Tropical Wet & Dry) Montreal Temperate Cold Winter (Continental Warm Summer) Alice Springs Australia Dry (arid/semiarid)

21. Practice Question #2 p. 75 Part b Question #2 p. 75 Part b Montreal & Alice Springs have wide temperature ranges Re. Temperature ; colder winter in Montreal Re. precipitation; more in Montreal Re. Months of summer; opposite summer months due to North & south Hemispheres

22. Practice Question #2 p. 75 Part c Different hemispheres give opposite seasons Question #2 p. 75 Part d Montreal = temperate cold winter (Cont. Warm Summer) Alice springs = Dry (Semi- arid) Question #3 p. 77 is a good practice question too.
