This paper deals with the large-scale meridional currents and differential rotation that exist in the radiative envelope of a nonmagnetic, early-type star, when departure from spherical symmetry is not too large. When the (turbulent) viscous time is not very small compared to the main-sequence lifetime, it is found that the mean rotation law inexorably evolves in time while leaving almost unaffected the much slower meridional currents. Accordingly, even though too small an eddy viscosity prevents a steady rotation law from being attained on the main sequence, it does not break up the smooth, almost steady circulation pattern into a "random circulation," as some authors have suggested.
