5 unusual facts about Coriolis


Coriolis

Coriolis effect, the apparent deflection of moving objects from a straight path when viewed from a rotating frame of reference

Gaspard-Gustave Coriolis (1792–1843), French mathematician, mechanical engineer and scientist

Equatorial Rossby wave

Equatorial Rossby waves, often called planetary waves, are very long, low frequency waves found near the equator and are derived using the equatorial Beta plane approximation, f = \beta y, where "β" is the variation of the Coriolis parameter with latitude, \beta = \frac{\partial f}{\partial y}.

SpaceShaft

More about the combined effects of wind loads and upthrust is discussed later, under the section of "Heave and roll behavior" which would describe the similar of a spar-buoy on a waterway and on the section "Wind force and Coriolis", likewise for bending and deflection on the structure.

Thermal wind

If we differentiate the geostrophic wind, \mathbf{v} g = \frac{1}{f} \mathbf{k} \times \nabla p \Phi (where \; f \; is the Coriolis parameter, \mathbf{k} is the vertical unit vector, and the subscript "p" on the gradient operator denotes gradient on a constant pressure surface)


Henry Stommel

Henry Stommel showed that the north-south gradient of the strength of the Coriolis force (the "beta effect") was responsible for the observed fact that the return flow of the slow interior gyre circulations is concentrated in fast moving western boundary currents, such as the Gulf Stream and the Kuroshio Current, a process known as western intensification.
