WebSpecifically, the Bulk Richardson number shear term in the SCP has been replaced by the effective bulk shear, while the 0-3 km storm-relative helicity (SRH) has been replaced by the effective SRH. The effective shear terms make little difference in the SCP calculation for typical supercell cases, but they result in a more realistic assessment ...
