Query: On weak-strong uniqueness and singular limit for the compressible
  Primitive Equations   This paper addresses the weak-strong uniqueness property and singular limit
for the compressible Primitive Equations (PE). We show that a weak solution
coincides with the strong solution emanating from the same initial data. On the
other hand, we prove compressible PE will approach the incompressible inviscid
PE equations in the regime of low Mach number and large Reynolds number in the
case of well-prepared initial data. To the best of the authors' knowledge, this
is the first work to bridge the link between the compressible PE with
incompressible inviscid PE.
