Coriolis force

English

Etymology

From Coriolis +‎ force, after French scientist Gaspard-Gustave Coriolis.

Noun

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[1], 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[2], 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.
