The two regimes of turbulent dissipation (Eq. (87)). As long as the local convective turn-over time remains shorter than the tidal period (t_conv < P_tide), the turbulent viscosity ν_t (in black dashed line) is independent of the tidal frequency, and the inverse quality factor k₂/Q = |Φ_II/U| (in red continuous line), given by Eq. (94), varies proportionally to the tidal frequency σ_l (so does also the tidal lag angle). When t_conv > P_tide, ν_t varies proportionally to the tidal period, whereas k₂/Q = |Φ_II/U| no longer depends on the tidal frequency. We note that ν_t and k₂/Q have been scaled by the value they take respectively for t_conv/P_tide → 0 and  + ∞.
