Thermal Rossby waves propagating in the azimuthal direction are found as solutions. The analogy to the case of Boussinesq convection in the presence of conical end surfaces of the annular region is emphasized. As in the latter case the results can be applied as an approximation for the description of the onset of anelastic convection in rotating spherical fluid shells.
