Abstract:
The alternating change of the two meiyu front rain-bands caused by the alternating change between the moist potential vorticities is discussed. The main factors of the change of moist potential vorticity are the vertical and horizontal divergence of moist potential vorticity flux as well as the vertical transport caused by the cumulus mass flux. Also discussed is the possibility that the WAVE-CISK conditional symmetric instability in the baroclinic moist atmosphere leads to the forming of the double rain-bands and their roller-shaped circulation features. Theoretical analyses show that the latitudinal disturbance scale-selection by the primitive moisture model of the latent heat release in cumulus convection depends on the stratification instability parameter (Ri number) and viscous coefficient of eddy.
