  Hemispheric irregularities of solar magnetic activity is a well-observed
phenomenon -- the origin of which has been studied through numerical
simulations and data-analysis techniques. In this work we explore possible
causes generating north-south asymmetry in the reversal timing and the
amplitude of polar field during cycle minimum. Additionally, we investigate how
hemispheric asymmetry is translated from cycle to cycle. We pursue a three-step
approach. Firstly, we explore the asymmetry present in the observed polar flux
and sunspot area by analyzing observational data of the last 110 years.
Secondly, we investigate contribution from different factors involved in the
Babcock-Leighton mechanism to the evolution and generation of polar flux by
performing numerical simulations with a Surface Flux Transport model and
synthetic sunspot input profiles. Thirdly, propagation of hemispheric asymmetry
in the following cycle is estimated by assimilating simulation-generated
surface magnetic field maps at cycle minimum in a dynamo simulation. Finally,
we assess our understanding of hemispheric asymmetry while reproducing observed
asymmetry in the eight past solar cycles by performing additional observational
data-driven simulations.
