Characteristic time scale of evolution of the rotation rate in the case of a low differential rotation δΩ = 0.15 × 10-6 rad s-1 (dashed lines) and a stronger one δΩ = 10-6 rad s-1 (solid lines). We compare the results obtained with a plume-induced wave spectrum (blue) and with a turbulence-induced wave spectrum (red) from the formalism of Kumar et al. (1999).
