High vorticity
http://www.theweatherprediction.com/habyhints/56/ WebThe primary feature of a vortex is that planar vorticity dominates over planar deviatoric strain rate and the flow becomes swirling in the cross-sectional plane which results (i) in the occurrence of a local pressure minimum in a plane and (ii) in elliptical deviatoric flow patterns of the projected planar velocity field near a point as discussed …

WebShear vorticity c. Earth vorticity (Coriolis) High vorticity is an indication of ageostrophic flow and upper level divergence (2) This is the best chart in assessing the trough/ ridge pattern . A trough is an indication of cooler … 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 and … 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 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.
