Differential rotation and meridional flow in the solar convection zone with AKA-effect

It makes no problem to reproduce the internal rotation of the solar convection zone known by helioseismology if (artificially) the meridional flow is ignored. Its inclusion, however, strongly reduces the latitudinal differences of the angular velocity even at the surface. The amplitude of this effect, known as the `Taylor number puzzle', depends on the unknown amplitude of the eddy viscosity. The effect in detail is described here making use of the mixing-length model of the solar convection zone by Stix & Skaley (1990). The resulting differential rotation profiles are far from the observations if indeed the free factor c in the eddy viscosity definition does not exceed unity. As one of the possibilities to escape the paradox the `anisotropic kinetic alpha' (AKA)-effect is here involved into the computations. We have already shown that it should appear in formulations of the mean-field hydrodynamics in rotating density-stratified turbulent fluids at the same time with the MHD alpha...
