Azimuthal wavenumber spectra of the velocity squared is shown for (a) case TUR and (b) case LAM. In each panel, solid lines correspond to a horizontal level near the top of the convection zone (﹩r=0.95﹩ R_⊙), dashed lines to a level in the mid convection zone (﹩r=0.84\,R_{\odot }﹩), and dotted lines to a level in the overshoot region (﹩r=0.72\,R_{\odot }﹩). All curves are averaged over a time interval of five rotation periods.
