In physics, the Coriolis force is an inertial (or fictitious) force that acts on objects in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object. In one with anticlockwise (or counterclockwise) rotation, the force ...
The Coriolis frequency ƒ, also called the Coriolis parameter or Coriolis coefficient, [1] is equal to twice the rotation rate Ω of the Earth multiplied by the sine of the latitude . The rotation rate of the Earth (Ω = 7.2921 × 10 −5 rad/s) can be calculated as 2 π / T radians per second, where T is the rotation period of the Earth which ...
An amphidromic point, also called a tidal node, is a geographical location where there is little or no difference in sea height between high tide and low tide; it has zero tidal amplitude for one harmonic constituent of the tide. [2] The tidal range (the peak-to-peak amplitude, or the height difference between high tide and low tide) for that ...
The structure will eventually dissipate due to friction and mixing of water properties. 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 ...
A Kelvin wave is a wave in the ocean, a large lake or the atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator. A feature of a Kelvin wave is that it is non-dispersive, i.e., the phase speed of the wave crests is equal to the group speed of the wave energy for ...
Shallow-water equations, in its non-linear form, is an obvious candidate for modelling turbulence in the atmosphere and oceans, i.e. geophysical turbulence. An advantage of this, over Quasi-geostrophic equations, is that it allows solutions like gravity waves, while also conserving energy and potential vorticity.
Taylor column. Motion of fluid above and below a moving object is forced to circulate, and are thus restricted to be within a column extended by the object in the axis of rotation. A Taylor column is a fluid dynamics phenomenon that occurs as a result of the Coriolis effect. It was named after Geoffrey Ingram Taylor.
This matrix can be seen as a constant tensor field, defined in the whole space, that will yield coriolis forces when multiplied by momentum vectors. Mach's view. In a theory that conforms to some versions of Mach's principle, this “apparent”, “fictitious” or “pseudo-gravitational” field effect can be treated as genuine.
