10Factors That Affect Climate J – Jet StreamB – Bodies of waterO – Ocean currentsW – Wind and air massesL – LatitudeE – Elevation and LandformsR - Relief
11Factor PowerCertain 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.
12Jet 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 season2 jet streams in northern hemisphere, 2 in the southernPolar Jet Streams are found at about 50-60N/S and the subtropical is found at about 30NForm where temperatures between air masses are the greatest (near poles). Caused by atmospheric heating and earth’s rotation.Jet Stream is found in the tropopause (boundary between the stratosphere and the troposphere) where winds are strongestkm/hr – faster in winter when temperature variations are greater.They change location based on the seasons. In North America, the polar jet stream is said to “follow the sun” because it moves north in the summer and a bit further south in the winter.
13Bodies of WaterBodies of water heat up and cool down more slowly than landConsider the desertBodies of water affect air temperature in the region
14Ocean CurrentsWarm and cold ocean currents make coastal locations warmer or colder than normal for its latitudeOcean current temperatures affect atmospheric conditions
15Winds and Air MassesAir mass is a huge body of air that has the characteristics of where it formedWinds blow from areas of high pressure to areas of low pressure
16Continental = formed over land (dry) Maritime = formed over water (moist)Arctic = cold to very coldPolar = cool to coldTropic = warm to hotcAcPcTmPmTWhat type of air mass would form over Regina, SK?
17Latitude 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 KenyaConsider the flashlight demonstration
19Elevation/AltitudeIs the vertical distance (height) of a landform from sea level to the top of the landform - altitudeWhat happens to the temperature as you climb up a mountain?Temperature drops as elevation increasesAir gets thinner and pressure decreases as elevation increases and is less able to retain heat from the sunAir closer to the earth’s surface has higher pressure = warmerAir Pressure is due to the weight of the air. Air that is closer to the ground, sea level, has higher pressure due to gravity
21ReliefThe difference in elevation between the highest and lowest points in an areaChange in topography (shape of land)Mountainous regions tend to have more precipitation. As air rises, it condenses and releases in various forms of precipitationExample: The Rocky Mountains
