Journal ArticleDOI
Westward drift, core motions and exchanges of angular momentum between core and mantle
TL;DR: In this article, it was shown that the change in the zonal toroidal flow inside the core consists of motions in which axial cylindrical annuli rotate rigidly about the Earth's axis of rotation.
Journal ArticleDOI
Scaling rules in rock fracture and possible implications for earthquake prediction
TL;DR: In this paper, a simple model based on scaling laws was proposed for fracture of rocks, which yields a criterion for fragility at different scales and views rupture as a critical point.
Journal ArticleDOI
A statistical approach to the Earth's main magnetic field
Gauthier Hulot,J. L. Le Mouël +1 more
TL;DR: In this paper, the Earth's main magnetic field can be described as a two-scale process, and the stationary isotropic statistical model described describes the behaviour of the field in statistical terms.
Journal ArticleDOI
Outer-core geostrophic flow and secular variation of Earth's geomagnetic field
TL;DR: In this article, it is shown that the Coriolis force will probably dominate the force budget at the top of the core and that, in such a case, the motion of the fluid involves the two parts of the field in a different way; in particular, the existing axial dipolar component is not reengaged in the process which builds up the SV.
Journal ArticleDOI
Motions at core surface in the geostrophic approximation
TL;DR: In this paper, motions at the top of the core which generate the observed Secular Variation (S.V) field are computed. But, to reduce the ambiguity of the solution, two constraints are added: the flow is a large scale one and is geostrophic.
