Differential Rotation

• On the surface of the sun the equatorial latitudes rotate faster than the polar latitudes

• Deeper layers in the sun rotate slower than surface layer near the equator and faster than surface layers in the poles.

Meridional Flow
 

• A circulatory axisymmetric flow in the meridional plane (r-theta plane) of stars. For the Sun the flow is observed to be poleward at the surface, sinks down at the poles and rises near the equator. From mass concervation it follows that there is a equatorward counterflow somewhere in the interior.
