An optimized tidal-trigger model of the QBO, and some implications for the Carrington event
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
Magneto-Rossby waves in the solar tachocline are currently being discussed as a potential cause of the quasi-biennial oscillation (QBO). By analyzing sequences of ground-level enha…
Tidal triggers and the predictability of solar activity
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
Magneto-Rossby waves in the solar tachocline are currently considered to be one of the main determinants of solar activity. In particular, they can give rise to the quasi-biennial…
Reappraising the Elatina series: Solar dynamo clocking and inference of orbital periods
F. Stefani, T. Weier, G. M. Horstmann +1
We reconsider the 680 million year old Elatina series of sedimentary laminae from South Australia that show a remarkably stable periodicity with a main period of around 12 years, w…
Adding further pieces to the synchronization puzzle: QBO, bimodality, and phase jumps
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
This work builds on a recently developed self-consistent synchronization model of the solar dynamo which attempts to explain Rieger-type periods, the Schwabe/Hale cycle and the Sue…
