helicity

he·lic·i·ty

 (hə-lĭs′ĭ-tē, hē′)
n. pl. he·lic·i·ties Physics
1. The projection of a particle's spin vector in the direction of its momentum vector, being positive if it points in the same direction, and negative if it points in the opposite direction. Helicity is the chirality of the particle's spin.
2. An instance of such projection.

Recently, Lei, Lin and Zhou in [17] proved the global well-posedness of 3D Navier-Stokes equations for a family of large initial data by making use of the structure of Helicity. The data in [17] are not small in [[??]-1.sub.[infinity],[infinity]] even in the anisotropic sense.

In the Electroweak Model, chirality and helicity are essential properties of subatomic particles, but these abstract concepts are difficult to visualize.

The 0-3km storm-relative helicity (SRH0-3) was also extremely high at 461[m.sup.2] [s.sup.-2], well above the threshold seen in strongly tornadic supercell environments [63].
