Profiles of the rms convective velocity, v_rms, and the Alfvén velocity of the rms magnetic field, $v_{\mathrm{A},\mathrm{rms}}=B_{\mathrm{rms}}/\sqrt{4\pi {\rho }_0}$. (a–d) Vertical profiles of v_rms for different Co_*, where blue and red represent the results from HD and MHD cases. The dashed green curves show the profiles of v_A, rms from MHD cases. (e) The values of volume-averaged rms velocity and magnetic field, ${\overline{v}}_{\mathrm{rms}}$ and ${\overline{v}}_{\mathrm{A},\mathrm{rms}}$, as functions of Co_*. The dotted gray lines show $\propto {\mathrm{Co}}_{\ast }^{-1/5}$ and $\propto {\mathrm{Co}}_{\ast }^{-1/3}$ dependences theoretically expected from the CIA and MAC balances.
