Estimates of the significance of the radial motions associated with the different inertial modes for the compressible setup, quantified using non-toroidicity Γ defined in Eq. (22). The values of non-toroidicity for different modes are plotted against azimuthal orders ranging from m = 1 to m = 10. Different colours represent different modes, as in Fig. 5. Solid lines denote modes under differential rotation, while dotted lines denote modes under uniform rotation. Open circles indicate modes affected by critical latitudes under differential rotation, while filled circles indicate other modes under differential rotation.
