http://twister.caps.ou.edu/MM2015/Chapter4.6c.pdf Web25 apr. 2012 · storm-relative environmental helicity (Abbreviated SREH.) A measure of the streamwise vorticity within the inflow environment of a convective storm. It is calculated by multiplying the storm-relative inflow velocity vector by the streamwise vorticity and integrating this quantity over the inflow depth.
WebStorm-Relative Vorticity Horizontal vorticity is the rolling motion induced by a change in wind with height. The vorticity vector points perpendicularly to the left of the shear vector per the right-hand rule: Stronger shear yields more horizontal vorticity, hence the vorticity vector is longer where shear is stronger.
Web7 mei 2024 · Helicity is the product of low level shearing (known as streamwise vorticity) and storm inflow directly into the streamwise vorticity. The Helicity is storm relative which means the Helicity is calculated from the storm's frame of reference This is a good definition, but it's difficult to understand without a picture or some kind of 3D animation.
