For 10 points, name this effect in which objects appear to deflect from a straight line when viewed from a rotating reference frame.
One result of this is that objects feel heavier or lighter depending on direction of motion, which is known as the Eötvös effect. The Ekman spiral is caused by this, and the ratio of inertial forces to forces caused by it is known as the Rossby number. Acceleration due to this effect is equal to negative two times the cross product of the system's angular velocity and the particle's velocity. It is directed radially inward for high pressure systems, and cyclones rarely form at the equator due to the absence of this effect.
