Cocke, W.J., 1967: On the solar differential rotation and meridional currents. Astrophys. J., 150, 1041-1052, doi:10.1086/149402.
The solar differential rotation, and large-scale meridional currents are investigated with the axially symmetric, time-independent hydrodynamic equations of motion, including anisotropic convective viscosity forces. The φ-component of the equations of motion is integrated to give a linear, ordinary differential equation determining the angular velocity distribution. The Reynolds number for the differential rotation in the convection zone is shown to be large, and an approximation based on this fact is used to solve the equations of motion to first order, under the assumption that the polar heating effects are negligible and that the convection zone is barytropic. A good fit to the observed differential rotation is obtained if the anisotropy parameter satisfies s-1 ≃ 1/5, and the differential rotation is then approximately independent of the magnitude of the dynamic convective viscosity η. The circulational velocities near the surface at high latitudes are ∼ (s-1)ρ-1 grad η. Reasonable agreement with observed values is shown.
