Helicity (particle physics) - Wikipedia
WebHelicity is a meteorological term that plays a significant role in severe storm prediction, tornado formation, and other weather phenomena. It represents the vertical wind shear’s degree of rotation, which is critical to understanding the behavior of storm systems. Helicity is measured in meteorology using various tools and techniques, and ...

The data displayed at right is taken at energies far above the range of neutrinos from radioactive decay. The slope of the straight line at right, when extrapolated down to 1 MeV, gives a cross section more like 10-45 m 2. push rocker switch factory
