The most recent solar inversions also show evidence for the presence of oscillations down to the deeper layers of the convection zone (Vorontsov et al. 2002; Antia & Basu 2004), but the precise dynamical nature of these regimes cannot be determined at present, given the current length of the helioseismological data set and the presence of noise. We have however shown, using a detailed comparison between model predictions and helioseismological inversions, that given the expected noise levels in the helioseismological data, our theoretical predictions are compatible with observations (Vorontsov et al. 2003). Our models also predict a polar branch of the torsional oscillations, and this feature has also been confirmed.
