Snapshots of the radial velocity field in simulation TUR are shown at a level near the top of the convection zone (﹩r=0.95\,R_{\odot }﹩). The time interval between each successive image is about 9 days, one‐third the rotation period of the coordinate system, P (= 28 days). Each surface is tilted 20°, such that the north pole points out of the plane of the page, as in Figs. 2 and 3. Light and dark regions denote upflow and downflow, respectively.
