Coriolis Effect

  • This is the rotating of the Earth towards the East
  • Speed of rotation varies at different latitudes
  • Forces moving objects on Earth to follow curved paths
    • In the Northern hemisphere, they follow path right of intended course
    • In the Southern hemisphere, they follow path left of intended course
  • Has great effect on atmospheric circulation and ocean currents/tides
  • In Northern hemisphere, most ocean basins have a circular current flow (gyre) rotating in clockwise direction
  • In Southern hemisphere, ocean gyres rotate in anti-clockwise direction
