Abstract:
Understanding the solar cycle is a fundamental and important objective in solar physics. Recent studies have revealed correlations between variations of the poleward transport of photospheric magnetic fields with properties of both magnetic field in solar active regions as well as their decay products. Features such as poleward surges
often play an outsized role in advecting flux away from the activity belts into polar regions, and therefore affect solar cycle activity. This report describes our plans and reviews preliminary results investigating the effects of active region-modified zonal and meridional flows on flux evolution and the solar cycle.
