On Polar Magnetic Field Reversal and Surface Flux Transport During Solar Cycle 24

Xudong Sun, J. Todd Hoeksema, Yang Liu +1

As each solar cycle progresses, remnant magnetic flux from active regions (ARs) migrates poleward to cancel the old-cycle polar field. We describe this polarity reversal process du…
