Diffusion and pattern formation in spatial games
Alexandre Champagne-Ruel, Sascha Zakaib-Bernier, Paul Charbonneau
Diffusion plays an important role in a wide variety of phenomena, from bacterial quorum sensing to the dynamics of traffic flow. While it generally tends to level out gradients and…
Towards an algebraic method of solar cycle prediction II. Reducing the need for detailed input data with ARDoR
Melinda Nagy, Kristóf Petrovay, Alexandre Lemerle +1
An algebraic method for the reconstruction and potentially prediction of the solar dipole moment value at sunspot minimum (known to be a good predictor of the amplitude of the next…
Towards an algebraic method of solar cycle prediction I. Calculating the ultimate dipole contributions of individual active regions
Kristóf Petrovay, Melinda Nagy, Anthony R. Yeates
We discuss the potential use of an algebraic method to compute the value of the solar axial dipole moment at solar minimum, widely considered to be the most reliable precursor of t…
Confinement of the solar tachocline by a cyclic dynamo magnetic field
R. Barnabé, A. Strugarek, P. Charbonneau +2
The surprising thinness of the solar tachocline is still not understood with certainty today. Among the numerous possible scenarios suggested to explain its radial confinement, one…
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…
Modelling turbulent stellar convection zones: sub-grid scales effects
A. Strugarek, P. Beaudoin, A. S. Brun +3
The impressive development of global numerical simulations of turbulent stellar interiors unveiled a variety of possible differential rotation (solar or anti-solar), meridional cir…
Characterisation of the turbulent electromotive force and its magnetically-mediated quenching in a global EULAG-MHD simulation of solar convection
C. Simard, P. Charbonneau, C. Dube
We perform a mean-field analysis of the EULAG-MHD millenium simulation of global magnetohydrodynamical convection presented in Passos et al. 2014. The turbulent electromotive force…
Hemispheric Coupling: Comparing Dynamo Simulations and Observations
Aimee A. Norton, Paul Charbonneau, Dario Passos
Numerical simulations that reproduce solar-like magnetic cycles can be used to generate long-term statistics. The variations in N-S hemispheric cycle synchronicity and amplitude pr…
Torsional Oscillations in a Global Solar Dynamo
P. Beaudoin, P. Charbonneau, E. Racine +1
We characterize and analyze rotational torsional oscillations developing in a large-eddy magnetohydrodynamical simulation of solar convection (Ghizaru, Charbonneau, and Smolarkiewi…
