globlal atmospheric circulation

• give 4 examples of types of precipitation?

  1. snow
  2. sleet
  3. freezing fog
  4. graupel
• give 3 examples of types of clouds?

  1. stratus
  2. cirrus
  3. cumulus
• what do SOME clouds bring?

  some clouds bring rain and some do not bring rain
• what is air likeat the equator?

  warm
• what does warm air at the equator do?

  Rises. this leads to low pressure , condensation, thunderclouds, daily clouds
• what happens after the warm air at the equator has risen?

  air spreads and cools
• what is found in between polar cell and ferrell cell?

  mid-latitude depression
• what is found in between ferrell cell and hadley cells?

  subtropical anticyclones
• what is found in between hadley cells and hadley cell?

  ITCZ
• what does ITCZ stand for?

  intertropical convergence zone
• what pressure is found at the poles?

  Polar high pressure
• is pressure low or high at the poles?

  high
• what is pressure like at the mid-latitude depressions?

  low
• what is pressure like at subtropical anticyclones?

  high
• what pressure is found at the ITCZ?

  low pressure
• how is low pressure created at the ferrell cell?

  the air masses push upwards, creating low pressure
• what does the cool air do at the hadley cell/ at 30 degree latitude?

  cool air sinks leading to high pressure /clear blue skies / desert conditions
• Which way do winds ALWAYS BLOW?

  From high pressure areas to low pressure areas
• what are winds deflected by?

  the Earth's spin
• which direction are winds deflected by the earths spin\?

  • to their right in the Northern hemisphere
  • to their left in the Southern hemisphere
  • this is called the CORIOLIS FORCE
