2.6 Elevation & Climate Understand the relationship between elevation & climate Chapter 4 p. 71

Define Elevation p. 71 Elevation = height of a region above sea level Figure 1.6 p. 8 shows cross section of Canada Winnipeg 239 m 4000 m Sea Level

DID YOU KNOW? Air temperature decreases 2oC for every 300m increase in elevation IT’S TRUE!! In fact, the higher up we go; the colder it gets; hence snow on mountain tops

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???? Stop La Paz & Rio de Janeiro have similar dist. from ocean & similar latitude. La Paz is much colder because of higher elevation . La Paz, Bolivia Elevation = 3600m Coldest month = 9oC Rio de Janeiro, Brazil Elevation = 61m Coldest month= 25oC

2.6.2 Describe the relationship between the elevation of a point and its temperature and precipitation. Relief Rainfall Windward Side of mountain Leeward Side of Mountain Rain shadow – What side?

Relief Rainfall – Recap!!! Elevation and Precipitation
Windward = side of a mountain wind blows toward Leeward = side of mountain opposite from windward Rain shadow = region on leeward side of mountain that receives little precipitation because most rain dropped on windward side.

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 temperatures Cities on leeward side have little rain Cities on windward side have more rain Match the city to the data 1113mm rain & 0oC coldest month 628mm rain & -12oC coldest month Prince George Vancouver wind
