Rotational dependency of meridional circulation and differential rotation and their effective counterparts. We plot the meridional circulation (first column) and (third column) at 25° latitude together with the azimuthal mean velocity (second column) and (fourth column) close to the surface at r = 0.99 R as a function Co for the HD runs (Set H) in the top row and for the MHD runs (Set M) in the bottom row. Positive(negative) values of are equatorward (poleward) and positive (negative) are prograde(retrograde). The zero values are indicated with a white line.
