Vorticity equation — The vorticity equation is an important prognostic equation in the atmospheric sciences. Vorticity is a vector, therefore, there are three components. The equation of vorticity (three components in the canonical form) describes the total… … Wikipedia
vorticity — is a measure of rotation in the atmosphere, or “spin,” in the air. If the spin, as viewed from above, is counterclockwise in the Northern Hemisphere, it is called a vorticity cyclonic and given a positive value. If the spin is clockwise, it is… … Aviation dictionary
Barotropic vorticity equation — A simplified form of the vorticity equation for an inviscid, divergence free flow, the barotropic vorticity equation can simply be stated as:frac{D eta}{D t} = 0,where frac{D}{D t} is the material derivative and:eta = zeta + fis absolute… … Wikipedia

Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… … Wikipedia
Stokes' law — In 1851, George Gabriel Stokes derived an expression, now known as Stokes law, for the frictional force also called drag force exerted on spherical objects with very small Reynolds numbers (e.g., very small particles) in a continuous viscous… … Wikipedia
Superfluid — Superfluidity is a phase of matter or description of heat capacity in which unusual effects are observed when liquids, typically of helium 4 or helium 3, overcome friction by surface interaction when at a stage, known as the lambda point for… … Wikipedia
