The Coriolis Force - continued

Properties of the coriolis force, continued:

  • the coriolis force is larger for parcels moving at faster speeds, it's zero if a parcel is not moving
  • the coriolis force is not that large for slow-moving objects or for those moving over short distances

NOTE: The coriolis force is an "apparent" force that arises solely due to the fact that the earth is rotating. Therefore, it can only change a parcel's direction, it CAN NOT affect its speed.
