Hi Axel
http://www.astronomynotes.com/starsun/sun-rotation.gif
The answer of course exists in the association between differential
rotation and a deviation from a perfect sphere.
While the Equatorial bulge of the Earth is a misnomer given that the
deviation covers the entire geometry from pole to Equator ,it is far
easier to use the Sun's surface as a rough guide and the differential
rotation bands that straddle the Equator and move in bands towards the
poles.
Geologists will not recognise the profile of the Earth as a geological
feature even though the motion of the component crustal plates which
profile the Earth's shape is better explained by differential rotation
bands than a stationary Earth/convection cells model.
