Abstract:
I review and discuss recent helioseismic measurements of the meridional circulation and solar rotation from analysis of mode eigenfunction perturbations. Results obtained from analysis of MDI data covering 2006-2010 and from HMI data covering 2010-1014 are shown. The method is verified using numerical simulations. The results are compared to other helioseismic measurements of the meridional flow.
