Simple models of magnetic field generation by convection in rotating
spherical shells exhibit properties resembling those observed on the sun. The
{assumption of the Boussinesq approximation made in these models} prevents a
realistic description of the solar cycle, but through a physically motivated
change in the boundary condition for the differential rotation the propagation
of dynamo waves towards higher latitudes can be reversed at least at low
latitudes.
