When does the tide occur because of centrifugal force?

Answer 1

There is no perceptible tidal offset due to centrifugal force. Apparent centrifugal force (it is a ficticous force to compensate for a rotating inertial frame) is a function of angular velocity and the distance to the axis of rotation. Because these are both constant at any point on earth, there is no effect on tides. Tides have many constituents, the two primary are solar(sun) and lunar(moon). Although the sun is much larger, because gravitational force is diminished at a rate of distance squared, lunar tide constituents are much more influential. Harbor geometry(Seiche) can also play a major role in near-shore tides.
