Abstract
Temporal variations of the subsurface meridional flow with the solar cycle have been reported by several authors. This work examines the possible contamination of the helioseismic measurements by the extra velocity fields associated with active regions as well as the uncertainties in the data obtained where strong magnetic fields are present. We compare meridional flows obtained by both ring-diagram and time-distance analysis before and after removing the areas of strong magnetic field. The preliminary results suggest that a careful examination of the contribution of magnetic regions to the longitude averaged meridional flow is required.
