Energy helicity index

WebEnergy-Helicity Index The basic premise behind the EHI ( E nergy- H elicity I ndex) is that storm rotation should be maximized when CAPE is large and SRH is large. 0-3-km EHI values greater than 1-2 have been associated with significant tornadoes in supercells. WebEnergy-Helicity Index. The basic premise behind the EHI (Energy-Helicity Index) is that storm rotation should be maximized when CAPE is large and SRH is large.0-1-km EHI values greater than 1-2 have been associated with significant tornadoes in supercells.

Role of cross-helicity in magnetohydrodynamic turbulence

WebSRH (Storm Relative Helicity) is a measure of the potential for cyclonic updraft rotation in right-moving supercells, and is calculated for the lowest 1-km and 3-km layers above ground level. There is no clear threshold value for SRH when forecasting supercells, since the formation of supercells appears to be related more strongly to WebJun 25, 2009 · Energy Helicity Index An index that incorporates vertical shear and instability, designed for the purpose of forecasting supercell thunderstorms Engineer's Level A telescope which is attached to a spirit-tube level, all revolving around a vertical axis and is mounted on a tripod.
