We discuss several singular limits for a scaled system of equations
(barotropic Navier-Stokes system), where the characteristic numbers become
small or ``infinite''. In particular, we focus on the situations relevant
in certain geophysical models with low Mach, large Rossby and large
Reynolds numbers. The limit system is rigorously identified in the
framework of weak solutions. The relative entropy inequality and careful
analysis of certain oscillatory integrals play crucial role.
