Flow patterns for hydrodynamical model H-Pr10-N5. Hammer projection of radial velocity u_r at r = 0.99 r_o is displayed in a), while the longitudinally averaged azimuthal velocity ⟨ u_φ ⟩ _φ (or differential rotation) is given in b). Red and blue indicate a downwelling and an upwelling flow in a) and a westward and an eastward flow in b). u_r and ⟨ u_φ ⟩ _φ are given in terms of the Reynolds number Re = u d/ν and the Rossby number Ro = u/ (dΩ) . The z component of vorticity is shown in c), where red and blue shades represent positive and negative vorticity. The colour variations are saturated at values lower than the extrema.
