This "fictitious" force causes flows in a rotating reference frame to be deflected from a straight line.
If the pressure gradient is balanced by this phenomenon, a flow is geostrophic. The combined effects of drag and this phenomenon create an Ekman spiral. The ratio of inertial forces to this phenomenon is given by the Rossby number. The strength of this phenomenon is directly proportional to the sine of latitude. This phenomenon results in cyclones spinning counter-clockwise in the Northern Hemisphere but clockwise in the Southern Hemisphere. This "fictitious" force causes flows in a rotating reference frame to be deflected from a straight line. For 10 points, name this effect that results from the Earth's rotation and which is not actually responsible for the way a toilet flushes.
If the pressure gradient is balanced by this phenomenon, a flow is geostrophic.
