Discriminating between Babcock–Leighton-type Solar Dynamo Models by Torsional Oscillations
The Astrophysical JournalThe details of the dynamo process in the Sun are an important aspect of research in solar-terrestrial physics and astrophysics. The surface part of the dynamo can be constrained by direct observations, but the subsurface part lacks direct observational ...

Neural differential equations for the solar dynamo
Physical Review EPhysical models aimed to reproduce basic features of the solar sunspot cycle are typically based on the solar dynamo mechanism. Usually qualitative arguments are used to define parameters of the model, among which a challenging component is the nonlinear form of quenching of the alpha-effect governing regeneration of the magnetic field.

Does the butterfly diagram indicate a solar flux-transport dynamo?
, 2004 We address the question whether the properties of the observed latitude-time diagram of sunspot occurrence (the butterfly diagram) provide evidence for the operation of a flux-transport dynamo, which explains the migration of the sunspot zones and the ...

Journal of Physics: Conference Series, 2008 Mean-field dynamo models and 3D magnetohydrodynamic (MHD) simulations of global-scale solar convection provide complementary insights into the origins of cyclic magnetic activity in the Sun. One particular class of mean-field dynamo models, known as the Babcock-Leighton Flux-Transport (BL-FT) modeling approach, has enjoyed much success recently in ...

On the Origin of Long-term Modulation in the Sun’s Magnetic Activity Cycle
The Astrophysical Journal LettersOne of the most striking manifestations of orderly behavior emerging out of complex interactions in any astrophysical system is the 11 yr cycle of sunspots.

Solar Field Mapping and Dynamo Behavior
Advances in Astronomy, 2012 We discuss the importance of the Sun’s large-scale magnetic field to the Sun-Planetary environment. This paper narrows its focus down to the motion and evolution of the photospheric large-scale magnetic field which affects many environments throughout ...

Tidal Control of Equatorial Vertical E × B Drift Under Solar Minimum Conditions
Geophysical Research LettersObservations show that equatorial ionospheric vertical drifts during solar minimum differ from the climatology between late afternoon and midnight. By analyzing WACCM‐X simulations, which reproduce this solar cycle dependence, we show that the interplay ...
