Scientific paper

The ideas of Gilman, Morrow, and DeLuca about how an emerging helioseismic picture of the Sun's internal rotation might affect the understanding of angular momentum transport and turbulent dynamo action in the solar interior are reviewed. Analysis of the frequency splittings of solar acoustic oscillations measured by Brown and Morrow suggests that the latitudinal differential rotation observed at the surface persists throughout the convection zone, and that the rotation is more uniform in the outer layers of the radiative interior. Taking this picture at face value, it is discussed qualitatively how angular momentum must be transported in order to sustain the observed rotation, the exchange of angular momentum between the convection zone and radiative interior, and the action of a turbulent dynamo which might be operating near the base of the convection zone. The qualitative scenario for the solar dynamo explains both the equatorward migration of the zone where sunspots appear and the observed poleward migration of non-sunspot magnetic field.
