(a) Normalized kinetic energy spectra, ${\displaystyle \sum _{k_y}}{\widehat{e}}_{\mathrm{kin}}$, in the middle convection zone (z = 1.1 H_r). Different colors represent different Co_*. Dashed and solid lines show the results from HD and MHD simulations, respectively. (b) Longitudinal wavenumbers where the kinetic energy spectra peak, ${\overline{k}}_{x,\mathrm{peak}}$, is plotted against the flux Coriolis number, Co_*. The blue and red circles are the results for the HD and MHD cases. (c) Same as panel b but as a function of the dynamical Coriolis number, Co${}_{\ell }=2{\mathrm{\Omega }}_0{\overline{\ell }}_x/{\overline{v}}_{\mathrm{rms}}$.
