    Atmospheric circulation
  •   Study   Slideshow
  • Describe the movement of warm air
    It rises
  •  15
  • When warm air rises, what happens to the area below it (in terms of pressure)
    It lowers
  •  15
  • Name the layer of the atmosphere where weather occurs
    Troposphere
  •  10
  • Identify the cells in the three cell model of air circulation
    Hadley, ferrel and polar
  •  15
  • Describe the location of three cells in the three cell model of air circulation
    Hadley is closest to the equator, ferrel in the middle (mid latitude), Polar near the poles
  •  25
  • Describe the orientation of the walker cells
    East to west
  •  15
  • Name the phenomenon that is caused by the walker cells
    ENSO
  •  20
  • What does ENSO stand for?
    El Nino Southern Oscillation
  •  10
  • Define "thermocline"
    abrupt temperature gradient in a body of water marked by a layer above and below which the water is at different temperatures
  •  20
  • Name the winds that come from the equator which influence the ENSO cycle
    Trade winds
  •  15
  • Explain El Nino using this image to help you
    Trade winds decrease, upwelling of cold water in east decreases and warm pool in west (thermocline)shallows. Less evaporation means less precipitation (drier
  •  25
  • Explain La Nina using this image to help you
    Trade winds increase, upwelling of cold water in east increases and warm pool in west (thermocline)deepens. More evaporation means more precipitation (wetter
  •  25
  • Distinguish between climate and weather
    Weather is the meteorological conditions: temperature and wind and clouds and precipitation. Climate is the long term observed weather condition affecting Eart
