Flux tube sizes and temporal evolution
Abstract
The present observational knowledge of the size distributions of solar surface magnetic structures-sunspots, sunspot groups and active regions-and their temporal evolution, is reviewed in the context of how such information may provide important clues to the nature of the solar dynamo and the underlying causes of solar variability. The ability of such information to distinguish between the competing theoretical mechanisms of flux tube fragmentation and coalescence is briefly discussed.
