Description

We present a formal derivation of compressible primitive equations for atmosphere modelling. They are obtained from the 3D compressible Navier–Stokes equations with an anisotropic viscous stress tensor depending on the density. Then, we study the stability of weak solutions to this problem by introducing an intermediate model obtained by a suitable change of variables. This intermediate model is more practical and it is simpler to achieve the main result
