We amend Babcock's original scenario for the global dynamo process thatsustains the Sun's 22-year magnetic cycle. The amended scenario fitspost-Babcock observed features of the magnetic activity cycle and convectionzone, and is based on ideas of Spruit and Roberts (1983) about magnetic fluxtubes in the convection zone. A sequence of four schematic cartoons lays outthe proposed evolution of the global configuration of the magnetic field above,in, and at the bottom of the convection zone through sunspot Cycle 23 and intoCycle 24. Three key elements of the amended scenario are: (1) as the netfollowing-polarity field from the sunspot-region omega-loop fields of anongoing sunspot cycle is swept poleward to cancel and replace theopposite-polarity polar-cap field from the previous sunspot cycle, it remainsconnected to the ongoing sunspot cycle's toroidal source-field band at thebottom of the convection zone; (2) topological pumping by the convection zone'sfree convection keeps the horizontal extent of the poleward-migratingfollowing-polarity field pushed to the bottom, forcing it to gradually canceland replace old horizontal field below it that connects the ongoing-cyclesource-field band to the previous-cycle polar-cap field; (3) in each polarhemisphere, by continually shearing the poloidal component of the settling newhorizontal field, the latitudinal differential rotation low in the convectionzone generates the next-cycle source-field band poleward of the ongoing-cycleband. The amended scenario is a more-plausible version of Babcock's scenario,and its viability can be explored by appropriate kinematic flux-transportsolar-dynamo simulations.
