    What affects climate What affects climate Presentation Transcript

    • Climate
    • What Affects Climate?
      • Science words :
        • Tropics
        • Polar zones
        • Temperate zone
    • Climate
      • Climate
        • Determined by averaging weather over a long period of time- at least 30 years
      • Temperatures on Earth
        • Range from -89.2 degrees C to 57.8 degrees C
      • Factors that affect a regions climate:
        • Latitude
        • Topography
        • Oceans and lakes
        • Ocean currents
        • Air mass
    • Latitude Affects Climate
      • Latitude close to equator receives most radiation
      • Tropics:
          • Region between latitudes 231/2 degrees north and 231/2 degrees south
      • Polar zones:
        • Solar energy hits at low angle
        • Polar ice reflects radiation
        • Never really warm
      • Temperate zones:
        • Between tropic and polar zones
        • Moderate
    • Topography Features Affect Climate
      • Large Bodies of Water
      • Coastal regions:
        • Warmer in winter, cooler in summer
      • Ocean currents
      • Moisture
        • Winds blowing from sea
          • Contain more moisture then land
        • Coast have wetter climate
          • Prevailing winds blow to coast
      • Mountains
      • Same latitude:
        • Mountain’s climate cooler then sea level
      • Less air molecules to absorb radiation
      • One side of mountain is cooler then other
        • Other side can contain a desert
      • Mountains and large bodies of water affect climate
      • Large cities -change weather patterns
    • Large Cities Affect Climate
      • Radiation strikes
        • Areas of vegetation
          • Radiation energy evaporated
        • City areas
          • Streets, parking lots, and buildings absorb radiation energy
          • Heat up and radiate heat into atmosphere
          • Car exhaust traps heat
            • “ heat island”
      • Large buildings
        • Change local winds and precipitation patterns
    • Climate Types
      • Science Words:
        • Adaptation
        • Hibernation
    • Climate Classification
      • Koppen Climate Types
      • Climates in six groups
        • Tropical
        • mild
        • dry
        • continental
        • polar
        • High elevation
      Climatologists- study climates use method to classify climate types 1918 – Wladimir Koppen- observed types of vegetation – region depends on climate of area
