Abstract It is shown that if the observed differential rotation of the Sun is generated in the lower, Boussinesq part of the convection zone (where the interaction of rotation with convection is important), a large pole-equator difference in flux would also have to be present. The Sun's angular velocity is evaluated as a function of depth and latitude under the assumption that the main effect of the interaction of rotation with convection is the generation of a small pole-equator difference in temperature in the lower part of the convection zone, which drives a meridional motion over the entire convection zone. The pole-equator difference in flux associated with this meridional circulation (which gives rise to the Sun's differential rotation) is negligible.
