Abstract
After reviewing the well established observational results on solar meridional flows in the near surface layers, I discuss recent time-distance helioseismic measurements on the deep structure of the circulation. I also discuss the limitations of such analyses due to noise and large systematics of unknown origins. Finally, I discuss implications for theoretical/numerical models of meridional circulation as well as for those which use it in modeling the solar dynamo.
