Helicity is, like energy, a quadratic invariant of the Euler equations of ideal fluid flow, although, unlike energy, it is not sign definite. In physical terms, it represents the degree of linkage of the vortex lines of a flow, conserved when conditions are such that these vortex lines are frozenRead More →
Helicity is simply a measure of the amount of rotation found in a storm’s updraft air. If there is significant rotation in a storm’s updraft air, the storm will more than likely become a supercell and possibly spawn one or more tornadoes. What is storm relative wind? The wind “felt”Read More →
