variability (BSISV) Vertical cloud structures of the northward pr
opagating BSISV Summary
Introduction
Sikka and Gadgil(1980);Cadet(1986); Lawrence and Webster(2002).
The meridional propagation of the BSISV is found to be intimately associated with active and break phases of the Asian summer monsoon
Jiang et al. (2004) Identified prominent meridional asymmetric structures associa
ted with the northward propagating BSISV.
Hsu et al.(2004);Fu et al.(2006)
The northward shift of low-level moisture perturbation relative to the BSISV convection, which may suggest a pre-conditioning process for its northward propagation.
An “easterly vertical wind shear” mechanism to explain the northward propagation of the BSISV.
