Abstract
The aim of this work is to study the solar-cycle variations of meridional flows and to investigate their variations in magnetic regions. Helioseismology observations indicate that mass flows around active regions are dominated by inflows into those regions.
We present a statistical study based on MDI/SOHO observations of 1996-2002 and show that this effect explains a significant part of the cyclic change of meridional flows in near-equatorial regions, but not at higher latitudes. A different mechanism driving solar-cycle variations of the meridional flow probably operates.
