The rossby number

WebbWe consider a singular limit problem for the Navier–Stokes system of a rotating compressible fluid, where the Rossby and Mach numbers tend simultaneously to zero. The limit problem is identified as the two-dimensional (2D) Navier–Stokes system in the “horizontal” variables containing an extra term that accounts for compressibility in the … WebbThis video derives the Rossby number in terms of the planetary vorticity (i.e., the Coriolis parameter) and describes the so-called traditional approximation...
