THE MOVEMENT OF AIR

  • Wind is air movement
  • The sun warms the earth, cause the circulation of air
  • The rising and sinking of air in earths atmosphere forms convection cells, these create high and low pressure belts
  • In the earth there is northern, western, eastern, and Southern Hemisphere. In these hemispheres, the wind has its own direction.

GLOBAL WINDS

  • The two factors that produce global winds are pressure belts and Coriolis
  • The locations where the major globe winds systems take place are the easterlies: blow east to west, westerlies: blow west to east and trade winds: blow east to west.
  • Jet streams are high-speed winds in the upper troposphere

LOCAL WINDS

  • These types of winds are short and go in many directions!
  • Sea and land breezes are caused from land and water being absorbed in the atmosphere and then being released.
  • Uneven heating in the earth cause most local winds! Like valley breezes.
  • Mountain breezes, when land and water release energy in a different way, causes mountain breezes.
