[9] [10] The effect was known in the early 20th century as the "acceleration of Coriolis", [11] and by 1920 as "Coriolis force". [ 12 ] In 1856, William Ferrel proposed the existence of a circulation cell in the mid-latitudes with air being deflected by the Coriolis force to create the prevailing westerly winds .
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.
The Coriolis force acts at right angles to the flow, and when it balances the pressure gradient force, the resulting flow is known as geostrophic. As stated above, the direction of flow is 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 .
If the Earth were tidally locked to the Sun, solar heating would cause winds across the mid-latitudes to blow in a poleward direction, away from the subtropical ridge. . However, the Coriolis effect caused by the rotation of Earth tends to deflect poleward winds eastward from north (to the right) in the Northern Hemisphere and eastward from south (to the left) in the Southern Hemisph
A requirement for the induction of field is a rotating fluid. Rotation in the outer core is supplied by the Coriolis effect caused by the rotation of the Earth. The Coriolis force tends to organize fluid motions and electric currents into columns (also see Taylor columns) aligned with the rotation axis.
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.
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.
In fluid dynamics, the Coriolis–Stokes force is a forcing of the mean flow in a rotating fluid due to interaction of the Coriolis effect and wave-induced Stokes drift. This force acts on water independently of the wind stress. [1] This force is named after Gaspard-Gustave Coriolis and George Gabriel Stokes, two
