%X Dynamic study is undertaken of the tropical atmospheric CISK-Rossby wave genesis and propagation mechanisms, the vertical structure of the low-frequency wave and the basic characteristics and constraint of the vertical transport of momentum and wave energy fluxes in relation to the quasi-biennial oscillation (QBO) of the stratospheric zonal winds over the tropics in the context of a baroclinic quasi-geoslrophic model. Results suggest that in the properly posed thermal conditions and zonal belt there exist two kinds of CISK-Rossby waves of low frequency (LF) and very low frequency (VLF), travelling zonally in opposite di-rections, which act as sources responsible for upward transferring momentum and wave energy fluxes for easterly and westerly perturbations in such a way as to provide required momentum and energy for the stratospheric QBO genesis and maintenance. The present study offers interpretations for some of the fun-damental observational facts of the QBO and proposes mew ideas of the QBO generation mechanism.
