Thus the Coriolis parameter, , is the angular velocity or frequency required to maintain a body at a fixed circle of latitude or zonal region. If the Coriolis parameter is large, the effect of the Earth's rotation on the body is significant since it will need a larger angular frequency to stay in equilibrium with the Coriolis forces.

A Taylor column is a fluid dynamics phenomenon that occurs as a result of the Coriolis effect. It was named after Geoffrey Ingram Taylor . Rotating fluids that are perturbed by a solid body tend to form columns parallel to the axis of rotation called Taylor columns.
A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars, with the high pressure to the right of the flow in the Northern Hemisphere, and the high pressure to the left in the Southern Hemisphere.
It descends, creating a cold, dry high-pressure area. At the polar surface level, the mass of air is driven away from the pole toward the 60th parallel, replacing the air that rose there, and the polar circulation cell is complete. As the air at the surface moves toward the equator, it deviates westwards, again as a result of the Coriolis ...
Support for the idea that the Coriolis field is a real physical effect and not just a mathematical artifact is justified by Machian theory. It notes that evidence of the field's existence is not only visible to the rotating observer; its distortion is also visible and verifiable for non-rotating onlookers.
A slope of one part in one million in sea surface height, for example, will result in a current of 10 cm/s at mid-latitudes. The fact that the Coriolis effect is largest at the poles and weak at the equator results in sharp, relatively steady western boundary currents which are absent on eastern boundaries. Also see secondary circulation effects.
The Coriolis effect induces an acceleration on the proof masses equal to = (), where is a velocity and is an angular rate of rotation. The in-plane velocity of the proof masses is given by X ip ω r cos ( ω r t ) {\displaystyle X_{\text{ip}}\omega _{r}\cos(\omega _{r}t)} , if the in-plane position is given by X ip sin ( ω r t ...
