The evolution of the photospheric magnetic fields at the poles of the Sun are cited as a predictor of sunspot cycle amplitudes. During each sunspot cycle, these polar fields are observed to form as flux from lower latitudes is advected poleward. In the research presented here, we measure the latitudinal transport flux caused by the separate advection and diffusion processes throughout a series of one-dimensional flux-transport models. These models are run forward in time since 2010, using a list of bipolar magnetic regions corresponding to sunspot cycles 24 and 25. By varying input parameters of the models, such as the diffusion coefficient and meridional flow profile, an ensemble of related models is built up that can be intercompared
