Query: Exact solutions to the compressible Navier-Stokes equations with the
  Coriolis and friction terms   We consider special solution to the 3D compressible Navier-Stokes system with
and without the Coriolis force and dry friction and find the respective initial
data implying a finite time gradient catastrophe.
