From the QBO to Rieger-type periods: Explaining extreme solar events by tidally triggered magneto-Rossby waves
F. Stefani, G. M. Horstmann, G. Mamatsashvili +1
It has recently been demonstrated that the occurrence of extreme solar events is governed by a phase-stable period close to 1.723 years (629.29 days). According to our previously d…
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: What if the Solar Interpretation Were Correct?
F. Stefani, M. Gugliotta, G. M. Horstmann +2
We revisit the sedimentary laminae from the Neoproterozoic Elatina Formation of South Australia. These were first interpreted as varves driven by solar activity and later as tidali…
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…
Rieger, Schwabe, Suess-de Vries: The Sunny Beats of Resonance
F. Stefani, G. M. Horstmann, M. Klevs +2
We propose a self-consistent explanation of Rieger-type periodicities, the Schwabe cycle, and the Suess-de Vries cycle of the solar dynamo in terms of resonances of various wave ph…
Tidally Forced Planetary Waves in the Tachocline of Solar-like Stars
G. M. Horstmann, G. Mamatsashvili, A. Giesecke +2
Can atmospheric waves in planet-hosting solar-like stars substantially resonate to tidal forcing? Substantially at a level of impacting the space weather or even of being dynamo-re…
