Meridional Circulation Dynamics in a Cyclic Convective Dynamo
D. Passos, M. Miesch, G. Guerrero +1
Surface observations indicate that the speed of the solar meridional circulation in the photosphere varies in anti-phase with the solar cycle. The current explanation for the sourc…
Meridional circulation dynamics from 3D MHD global simulations of solar convection
Dario Passos, Paul Charbonneau, Mark Miesch
The form of the solar meridional circulation is a very important ingredient for mean field flux transport dynamo models. Yet a shroud of mystery still surrounds this large-scale fl…
Oscillator models of the solar cycle: Towards the development of inversion methods
Ilídio Lopes, Dário Passos, Melinda Nagy +1
This article reviews some of the leading results obtained in solar dynamo physics by using temporal oscillator models as a tool to interpret observational data and dynamo model pre…
A Solar Dynamo Model Driven by Mean-Field Alpha and Babcock-Leighton Sources: Fluctuations, Grand-Minima-Maxima and Hemispheric Asymmetry in Sunspot Cycles
D. Passos, D. Nandy, S. Hazra +1
Extreme solar activity fluctuations and the occurrence of solar grand minima and maxima episodes, are well established, observed features of the solar cycle. Nevertheless, such ext…
A Stochastically Forced Time Delay Solar Dynamo Model: Self-Consistent Recovery from a Maunder-like Grand Minimum Necessitates a Mean-Field Alpha Effect
Soumitra Hazra, Dário Passos, Dibyendu Nandy
Fluctuations in the Sun's magnetic activity, including episodes of grand minima such as the Maunder minimum have important consequences for space and planetary environments. Howeve…
Effects of cyclic fluctuations in meridional circulation using a low order dynamo model
Dário Passos, Ilídio Lopes
We develop and subsequently explore the solution space of a simple flux transport dynamo model that incorporates a time dependent large scale meridional circulation. Based on recen…
Grand Minima Under the Light of a Low Order Dynamo Model
Dario Passos, Ilidio P. Lopes
In this work we use a low order dynamo model and study under which conditions can it reproduce solar grand minima. We begin by building the phase space of a proxy for the toroidal…
