Thermal Rossby number Ro_T plotted against the non-dimensional radiative timescale ${\widehat{\tau }}_{\text{rad\hspace{0.17em}}}$ for the complete sample of planets discussed in this study. The plotted quantities are calculated according to the definitions given in Sect. 2.1 and at the approximate photosphere corresponding to p = 0.7 bar. Chosen examples are highlighted together with their OLR profiles overplotted in the figure. The dashed lines correspond to a boundary between circulation regimes identified by Hammond et al. (2023). The red star is included as a reference point, the same as in Figure 1, corresponding to a run case of (T_eff = 400 K; P_rot = 10 h; log g = 4.46) from a recent GCM study.
