1 Climate

2 LOWERN There are 6 factors that affect climate Latitude Ocean Currents
Wind/Air Mass Elevation Relief Near Water

3 Latitude Distance from the equator
Further from the equator, the greater the area the sun’s energy covers

4 Latitude

5 How does Latitude Affect Climate?
As latitude ________, the average annual temperature _________. increases decreases 0° Latitude ° Temperature

6 Ocean Currents The temperature of an ocean current affects the temperature of the air that passes above it

7 Ocean Currents In the Gulf Stream- warm, moist air is carried from the Gulf of Mexico to Nova Scotia and the southern parts of Newfoundland The warm North Pacific current heats the cool air passing over it, giving a mild climate to Coastal British Columbia The cold Labrador Current cools the air of Labrador and Northern Newfoundland Where the Labrador Current and Gulf Stream meet ( over the Grand Banks) the weather is often damp and foggy

8 Ocean Currents

9 Gulf Stream

10 Warm Currents: warmer climate Cold Currents: cooler climate
How do ocean currents affect climate? Warm Currents: warmer climate Cold Currents: cooler climate

11 Wind/Air Mass

12 Prevailing Winds In Canada, the prevailing winds called Westerlies, blowing from west to east. Temperature of the winds depend on if they originated from the equator or the poles 

13 Wind/Air Mass The weight of air is called air pressure
Two types of Air Pressure: High and Low High Pressure- when rising air cools and falls towards the earth Low Pressure- when warm air, above heated ground, rises

14 Effect of High Pressure on Climate and Weather
High pressure is associated with clear, sunny days Air is cool and dry

15 Effect of Low Air Pressure on Climate and Weather
Low air pressure is usually associated with warm, moist air This also creates clouds

16 Elevation

17 WHY??? Elevation How does elevation affect Climate? As elevation
_____________, the Average annual Temperature _____________ Elevation Temperature increases decreases WHY???

18 Relief

19 Windward Side: ___________ Leeward Side: _____________
Relief How does relief affect climate? Windward Side: ___________ Leeward Side: _____________ cool, moist warm, dry

20 Relief The leeward sides of the Adirondacks & Catskills receive much less precipitation The windward sides of the Adirondacks & Catskills receive a great deal more precipitation

21 Near Water Bodies of water have a moderating effect on land temperatures. HOW? Oceans and large lakes heat up and cool down at a slower rate than the surrounding land So in the winter, the water retains heat longer and keeps climate to surrounding land warmer In summer, water takes longer to heat up, cooling the climate in the surrounding land

22 Near Water

23 Near Water Water __________ the temperature.
How does closeness to a large body of water affect climate? Water __________ the temperature. _______ summers. _______ winters. moderates Cooler Warmer Cities A & B are located at the same latitude. City B is closer to a large body of water. Its temperature line is flatter (moderated).

24 Climate Zones of Canada

25 Arctic Climate Zone Characteristics Cold winters, cool summers
Precipitation - low amount (less than 50 cm) snow High winds Coastal areas are warmer and have heavier snow falls

26 Mountain Characteristics Very diverse because of the 2 mountain ranges
Summers tend to be dry, with wetter winters Temperatures tend to drop the higher you get in elevation Precipitation- West side of Coastal Mnts cm - East side of Coastal Mnts cm - West side of Rockies- 120 cm

27 West Coast Characteristics Very wet (60- 400cm precipitation)
Cool summers, mild winters

28 Boreal Characteristics
Temperature range is large because zone covers large area latitudinal Precipitation is generally low, with higher amounts in the eastern coastal areas

29 Prairie Characteristics Extreme temperature range Windy
Generally very dry

30 Southeastern Characteristics Cool winters, warm to hot summers
Prone to highly changeable weather Moderate precipitation- various forms One of the major storm tracks of North America
