Coriolis force (plural Coriolis forces)

1. (physics, meteorology) A fictitious force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame.

   Coordinate term: Coriolis effect

   • 2006, J. Gordon Leishman, Principles of Helicopter Aerodynamics‎, page 197:

     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.

   • 2013, C. H. Townes, A.L. Schawlow, Microwave Spectroscopy, page 30:

     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.

   • 2013, Jack Williams, The AMS Weather Book: The Ultimate Guide to America's Weather‎, page 56:

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