  • high pressure 

    calm weather
  • low pressure

    clouds and rain

    A) polar cell
    B) Ferrell cell
    C) hadley cell
    D) hadley cell
    E) ferrel cell
    F) polar cell
  • polar cell

    above 60' North - Artic circle
    below 60' south - Antarctic circle
  • ferrel cell

    between 30'North and 60'north
    between tropic of cancer and Artic circle
    between 30'south and 60'south
    between tropic of Capricorn and Antarctic circle
  • hadley cell
    between 0' and 30'north
    between equator and tropic of cancer
    between 0' and 30' south
    between equator and tropic of Capricorn
  • Equator 

    closest to the sun
    highest temperatures
    concentrated rays
  • Poles - north and south 

    sun light / rays = more spread out
    colder
    low concentration of rays
  • low pressure

    warm air moves away from the Earth's surface - creates clouds - therefore, rainy and unsettled conditions
  • high pressure 

    cold air moving down towards the Earth - creates calm and settled weather conditions
