Storm relative helicity values

WebEffective Storm Relative Helicity (m 2 s -2) Effective SRH ( S torm R elative H elicity) is based on threshold values of lifted parcel CAPE (100 J kg -1) and CIN (-250 J kg -1 ). … Web2 days ago · The values μ 2 = − μ < 0; Γ 2 = − Γ < 0; θ 2 = π − θ; φ 2 = φ correspond to the mirror image with respect to the solid boundary when the intensity of the sink of the mirror image of the HV has the same value as that of the HV. 18 18.
