The solar polar magnetic field is of great interest as it is where solar magnetic field reversal starts. Surface and subsurface plasma flows are very important in understanding the field reversal because magnetic field flux is transported to solar high latitude from lower latitude according to flux transport theory. Local helioseismology has been able to derive subsurface flow fields, rotation rates, and meridional flows up to 30 Mm in depth. The results obtained by time-distance helioseismology during Solar Cycle 23 from SOHO/MDI have also revealed significant changes of the speed and the longitudinal structure of the flows. We used these measurements to compare with the magnetic flux transport determined from the magnetic field synoptic data. Furthermore, by use of MDI dynamic campaign observations and a recent high resolution observation of solar South Pole by Hinode, we explore the possibility to detect subsurface flow fields in solar high latitude.
