A general discussion by Anders Persson of various aspects of the coriolis effect, including Foucault's Pendulum and Taylor columns. The coriolis effect in meteorology PDF-file. 5 pages. A detailed explanation by Mats Rosengren of how the gravitational force and the rotation of the Earth affect the atmospheric motion over the Earth surface. 2 ...
Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the wind stress curl . [ 1 ] Gyre can refer to any type of vortex in an atmosphere or a sea , [ 2 ] even one that is human-created, but it is most commonly used in terrestrial oceanography to refer to ...
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 mentioned, 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 .
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1] Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and ...
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
[5] [6] Walter M. Elsasser, considered a "father" of the presently accepted dynamo theory as an explanation of the Earth's magnetism, proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth. He revealed the history of the Earth's magnetic field through pioneering the study of the magnetic ...
The Ekman spiral occurs as a consequence of the Coriolis effect. The Ekman spiral is an arrangement of ocean currents: the directions of horizontal current appear to twist as the depth changes. [1] The oceanic wind driven Ekman spiral is the result of a force balance created by a shear stress force, Coriolis force and the water drag. This force ...
Cyclonic rotation or cyclonic circulation is the atmospheric motion in the same direction as a planet's rotation, as opposed to anticyclonic rotation.In the case of Earth's rotation, the Coriolis effect causes cyclonic rotation to be in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere.
