Dynamo Models of the Solar Cycle [PDF]

open access: yesLiving Reviews in Solar Physics, 2005
This paper reviews recent advances and current debates in modeling the solar cycle as a hydromagnetic dynamo process. Emphasis is placed on (relatively) simple dynamo models that are nonetheless detailed enough to be comparable to solar cycle ...

Solar cycle variations in equatorial ionospheric zonal electric fields near sunrise

open access: yesEarth and Planetary Physics, 2023
In this study, we investigate the solar cycle dependence of the sunrise ionospheric zonal electric fields at the equator under geomagnetically quiet conditions.

The 8‐Year Solar Cycle During the Maunder Minimum

open access: yesAGU Advances, 2023
The presence of grand minima, characterized by significantly reduced solar and stellar activity, brings a challenge to the understanding of solar and stellar dynamo. The Maunder Minimum (1645–1715 AD) is a representative grand solar minimum.

Universal dynamo paradigm for solar activity, Higgs fields and disasters [PDF]

open access: yesEPJ Web of Conferences, 2021
There is still a problem of a correct and accurate description of the dynamo and its uses in various fields of physics. To solve this problem, a special and universal representation of dynamo is proposed.

The role of the bow shock in solar wind-magnetosphere coupling [PDF]

open access: yesAnnales Geophysicae, 2011
In this paper we examine the role of the bow shock in coupling solar wind energy to the magnetosphere using global magnetohydrodynamic simulations of the solar wind-magnetosphere interaction with southward IMF.

Nonlinearity, time delay, and Grand Maxima in supercritical Babcock-Leighton dynamos

open access: yesJournal of Space Weather and Space Climate, 2023
The physical origin of centennial and millennial-scale variations in solar activity remains ill-understood. Although stochastic fluctuations of the solar dynamo are unavoidable in view of the turbulent nature of the solar convection zone, the ...

Theoretical study of the ionospheric dynamo region inside the South Atlantic Anomaly

open access: yesEarth and Planetary Physics, 2023
The South Atlantic Anomaly (SAA) is a region where the geomagnetic field is significantly lower than that of the surrounding area. On the basis of the models of CHAOS-7.8, Mass Spectrometer Incoherent Scatter Model (NRLMSISE-00), and International ...

Models for the long-term variations of solar activity

open access: yesLiving Reviews in Solar Physics, 2023
One obvious feature of the solar cycle is its variation from one cycle to another. In this article, we review the dynamo models for the long-term variations of the solar cycle.
