Coriolis force

plural Coriolis forces

1. climatologyA fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame.

   First, we'll look at a simplified picture of how the pressure gradient and Coriolis forces affect an air parcel high above the ground.

   On a rotor, Coriolis forces will appear whenever there is a radial lengthening or shortening of the blade about the rotational axis, which will be a result of blade flapping or bending.

   These terms are generally thought of as due to Coriolis forces, and represent a coupling of the modes of vibration ω₂ and ω₃ Coriolis forces in the rotating molecule. The Coriolis force is a fictitious force which must be introduced if mechanical motion is studied in a rotating coordinate system and the rotation is otherwise overlooked.
