    Differential rotation axes

    Fluid bodies like gas planets and stars undergo differential rotation - as do the atmospheres of Earth, Venus etc, and oceans.

    Different speeds are often quoted, like for latitudes of Sun, Jupiter etc..

    But do different latitudes and different depths of such bodies also rotate around different axes?

    I'd think not. It'd create wind shear....intersecting winds blowing in different directions. It's a problem in little aircraft when the winds blow in distinctly different directions at altitudes near each other. when a pilot sees mare's tail clouds, it's a sign of wind shear, and no matter what the size of your aircraft you better have yiur seat belt on.

    The only overall rotation without local eddies would be uniform like a solid but since there are heating and tidal effects there is bound to be disruption in any real fluid body and like the hairy sphere topology model, there must then be discontinuities which means in practice lots of localised rotation with angular momentum effects.
