Description

The large-scale magnetic field of the Sun is shaped by the interplay of active-region emergence, random-walk dispersal in supergranulation, and advective transport in the meridional flow and differential rotation. In that process, active region nests, the plage state, and flow-field interactions are important to the formation and evolution of active regions, and likely to the global dynamo process. In this talk, I plan to review observations and numerical experiments, looking for an emerging picture, while identifying some of the open questions.
