text: The coriolis force is just a fictitious force that comes from trying to describe a rotating noninertial frame as an inertial frame (the centrifugal force is another one). Anytime there is a rotating noninertial frame, the motion can be more easily analyzed using the coriolis paradigm. And of course, the universe is FULL of rotating noninertial frames; planets, stars, solar systems, galaxies, etc.
