Vorticity is positive when – looking down onto the earth's surface – the wind turns counterclockwise. In the northern hemisphere, positive vorticity is called cyclonic rotation, and negative vorticity is anticyclonic rotation; the nomenclature is reversed in the Southern Hemisphere. See more In continuum mechanics, vorticity is a pseudovector field that describes the local spinning motion of a continuum near some point (the tendency of something to rotate ), as would be seen by an observer located at that point … See more In a mass of continuum that is rotating like a rigid body, the vorticity is twice the angular velocity vector of that rotation. This is the case, for example, in the central core of a Rankine vortex. The vorticity may be nonzero even when all particles are … See more The evolution of the vorticity field in time is described by the vorticity equation, which can be derived from the Navier–Stokes equations. In many real flows where the viscosity can be neglected (more precisely, in flows with high See more Aeronautics In aerodynamics, the lift distribution over a finite wing may be approximated by assuming that each … See more Mathematically, the vorticity of a three-dimensional flow is a pseudovector field, usually denoted by $${\displaystyle {\vec {\omega }}}$$, defined as the curl of the velocity field $${\displaystyle {\vec {v}}}$$ describing the continuum motion. In Cartesian coordinates See more A vortex line or vorticity line is a line which is everywhere tangent to the local vorticity vector.
