Variational estimation of the large scale time dependent meridional circulation in the Sun: proofs of concept with a solar mean field dynamo model
Ching Pui Hung, Allan Sacha Brun, Alexandre Fournier +3
We present in this work the development of a solar data assimilation method based on an axisymmetric mean field dynamo model and magnetic surface data, our mid-term goal is to pred…
Estimating the deep solar meridional circulation using magnetic observations and a dynamo model: a variational approach
Ching Pui Hung, Laurène Jouve, Allan Sacha Brun +2
We show how magnetic observations of the Sun can be used in conjunction with an axisymmetric flux-transport solar dynamo model in order to estimate the large-scale meridional circu…
Turbulent geodynamo simulations: a leap towards Earth's core
Nathanaël Schaeffer, Dominique Jault, Henri-Claude Nataf +1
We present an attempt to reach realistic turbulent regime in direct numerical simulations of the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidl…
