TLDR
In this paper, a low-order dynamo model was used to reproduce solar grand minima under certain conditions, such as the balance between meridional circulation and magnetic diffusivity, and the field intensification by buoyancy driven instabilities.About:

Flux Transport Dynamos: From Kinematics to Dynamics
TL;DR: This article reviewed the formulation and application of FTD models and assessed their current understanding of the input physics based largely on complementary 3D MHD simulations of solar convection, dynamo action, and flux emergence.

Revisited Sunspot Data: A New Scenario for the Onset of the Maunder Minimum
TL;DR: The Maunder minimum forms an archetype for the Grand minima, and detailed knowledge of its temporal development has important consequences for the solar dynamo theory dealing with long-term solar activity evolution.

Importance of Meridional Circulation in Flux Transport Dynamo: The Possibility of a Maunder-like Grand Minimum
TL;DR: In this paper, the authors model the last 23 sunspot cycles by varying the meridional circulation speed and find that most of the cycle amplitudes also get modeled up to some extent when they model the periods.

A stochastically forced time delay solar dynamo model: self-consistent recovery from a maunder-like grand minimum necessitates a mean-field alpha effect
TL;DR: In this paper, a stochastically forced, non-linear delay differential equation is used to study solar cycle fluctuations in which time delays capture the physics of magnetic flux transport between spatially segregated dynamo source regions in the solar interior.
Journal ArticleDOI
Understanding Solar Cycle Variability
TL;DR: In this article, the variability of the solar cycle can be essentially understood in terms of a weakly nonlinear limit cycle affected by random noise, which leads to a generic normal-form model, whose parameters are all constrained by observations.

The Maunder Minimum
TL;DR: In the years around a sunspot maximum there is seldom a day when a number of spots cannot be seen, and often hundreds are present.
Journal ArticleDOI
Dynamo Models of the Solar Cycle
TL;DR: In this paper, a series of increasingly complex dynamo models are constructed, with the primary aim of reproducing the various basic observed characteristics of the solar magnetic activity cycle, and global and local magnetohydrodynamcial simulations of solar convection, and dynamo action therein, are also considered.

An active Sun throughout the Maunder Minimum
TL;DR: In this paper, the dates of maxima and minima of the Maunder Minimum can now be reliably estimated by measuring the 10Be concentration in the Dye 3 ice core.

The Sun and the Earth’s Climate
TL;DR: A review of the evidence for a solar influence on the lower atmosphere and mechanisms whereby the Sun may produce more significant impacts than might be surmised from a consideration only of variations in total solar irradiance can be found in this article.
