Rogue Active Regions and the Inherent Unpredictability of the Solar Dynamo
Abstract
New developments in surface flux transport modeling and theory of flux transport dynamos have given rise to the notion that certain large active regions with anomalous properties (location, tilt angle and/or Hale/non-Hale character) may have a major impact on the course of solar activity in subsequent years, impacting also on the amplitude of the following solar cycles. Here we discuss our current understanding of the role of such ``rogue'' active regions in cycle-to-cycle variations of solar activity.
