6 Your Job…  Access the J. BOWLER worksheet online.  As you go to each station, complete the worksheet to learn about each factor that affects climate  Use your textbook to supplement the station information

7 Weather is…  The short-term, day-to-day conditions in the atmosphere  Examples: rain, sun, sleet, snow, wind  The weather today can be described as…

8 Climate is…  The weather conditions of a particular region averaged over a long period of time  Example: Prairie, Subarctic, Mountain, Atlantic…

9 Introducing J. Bowler I wonder if they have any clue how much I know about climate in Canada? Hmmmm. I love my skateboard I’m the world’s best bowler

10 Factors That Affect Climate  J – Jet Stream  B – Bodies of water  O – Ocean currents  W – Wind and air masses  L – Latitude  E – Elevation and Landforms  R - Relief

11 Factor Power  Certain factors have more of an impact in certain regions than in others, depending on geographic location, time of year, etc.  Therefore, some regions are more heavily influenced by 1-2 factors compared to other regions.

12 Jet Stream (Polar) Layer of fast moving, high-altitude air that forms boundary between cold air masses from the north and warm air masses from the south “Follow the sun” and change location with the season

13 Bodies of Water  Bodies of water heat up and cool down more slowly than land  Consider the desert  Bodies of water affect air temperature in the region

14 Ocean Currents  Warm and cold ocean currents make coastal locations warmer or colder than normal for its latitude  Ocean current temperatures affect atmospheric conditions

15 Winds and Air Masses  Air mass is a huge body of air that has the characteristics of where it formed  Winds blow from areas of high pressure to areas of low pressure

16 Continental = formed over land (dry) Maritime = formed over water (moist) Arctic = cold to very cold Polar = cool to cold Tropic = warm to hot cA cP cT mP mT What type of air mass would form over Regina, SK?

17 Latitude  Distance from the equator affects climate  Canada is located closer to the north pole than the equator therefore we have a colder climate than say Kenya  Consider the flashlight demonstration

18

19 Elevation/Altitude  Is the vertical distance (height) of a landform from sea level to the top of the landform - altitude  What happens to the temperature as you climb up a mountain?  Temperature drops as elevation increases  Air gets thinner and pressure decreases as elevation increases and is less able to retain heat from the sun  Air closer to the earth’s surface has higher pressure = warmer

20

21 Relief  The difference in elevation between the highest and lowest points in an area  Change in topography (shape of land)  Mountainous regions tend to have more precipitation. As air rises, it condenses and releases in various forms of precipitation  Example: The Rocky Mountains

22 Elevation and Relief

23 Windward Side Leeward Side Rain Shadow Define the terms windward, leeward, rain shadow and relief precipitation In your own words, how would you describe what this diagram is showing?

24 Relief/Orographic Precipitation

25 Work It!  Use pages to complete your chart. You can work individually or with your elbow partner.  Compare your charts and diagrams with a classmate
