1 2.6 Elevation & ClimateUnderstand the relationship between elevation & climateChapter 4 p. 71
2 Define Elevation p. 71Elevation = height of a region above sea levelFigure 1.6 p. 8 shows cross section of CanadaWinnipeg 239 m4000 mSea Level
3 DID YOU KNOW?Air temperature decreases 2oC for every 300m increase in elevationIT’S TRUE!! In fact, the higher up we go; the colder it gets; hence snow on mountain tops
4 2.6.2 Describe the relationship between the elevation of a point and its temperature and precipitation.See Figure 4.19 – Textbook…what is the relationship between temperatures and elevation????StopLa Paz & Rio de Janeiro have similar dist. from ocean & similar latitude. La Paz is much colder because of higher elevation .La Paz, BoliviaElevation = 3600mColdest month = 9oCRio de Janeiro, BrazilElevation = 61mColdest month= 25oC
5 2.6.2 Describe the relationship between the elevation of a point and its temperature and precipitation.Relief RainfallWindward Side of mountainLeeward Side of MountainRain shadow – What side?
6 Relief Rainfall – Recap!!! Elevation and Precipitation Windward = side of a mountain wind blows towardLeeward = side of mountain opposite from windwardRain shadow = region on leeward side of mountain that receives little precipitation because most rain dropped on windward side.
7 2.6.3 Analyze the relationship between temperature and precipitation of a point and its location relative to a mountain system.Cities higher up in a mountain have colder temperaturesCities on leeward side have little rainCities on windward side have more rainMatch the city to the data1113mm rain & 0oC coldest month628mm rain & -12oC coldest monthPrince GeorgeVancouverwind
