Rayleigh Bénard convection problem involves an unstable temperature gradient driving the pertur- bations to grow for a single fluid or even a mixture of fluids without phase transformation. However, when the mixture of fluids involve phase transformation, apart from the cooling experienced by the parcel as it relaxes to the temperature of its surrounding, it also experiences the latent heat release or absorption associated with the phase transformation. Troposphere, the convection dominated regime
In this work, we discussed the role of parallel flow shear in controlling the secondary pattern selection problem in drift wave turbulence. The principal results of this paper are summarized as follows. (-- removed HTML --) (-- removed HTML --) (-- removed HTML --) 1.

The overall dynamics is governed
