Radial profile of the latitudinally averaged turbulent velocity u_rms^′ of all runs. The colors indicate the different run sets with different Re as indicated. The solid lines show M runs, the dotted lines show S runs and the dashed lines show H runs, The thick green line indicates the values from the solar model of Stix (2002) based on mixing-length theory. The inset shows u_rms^′ at a fixed radius r = 0.9 R as a function of Re. There, we overplot u_rms^′ of Hotta & Kusano (2021) using the Re estimated in HKS22 (solid red) and a reestimate according to Eq. (16) (dashed).
