Geomagnetic Core Field Secular Variation Models
Space Science Reviews, 2009 We analyse models describing time changes of the Earth’s core magnetic field (secular variation) covering the historical period (several centuries) and the more recent satellite era (previous decade), and we illustrate how both the information contained in the data and the a priori information (regularisation) affect the result of the ill-posed ...

The geomagnetic secular‐variation timescale in observations and numerical dynamo models
Geophysical Research Letters, 2011 International audienceThe knowledge of the spatial power spectra of the main geomagnetic field and of its secular variation makes it possible to define typical timescales t n for each spherical harmonic degree n.

On equatorially symmetric and antisymmetric geomagnetic secular variation timescales
Physics of the Earth and Planetary Interiors, 2018 It has been suggested that the secular variation (SV) timescales of the geomagnetic field vary as (where is the spherical harmonic degree), except for the dipole.

Accounting for magnetic diffusion in core flow inversions from geomagnetic secular variation
Geophysical Journal International, 2008 International audienceWe use numerical dynamos to investigate the possible role of magnetic diffusion at the top of the core. We find that the contribution of radial magnetic diffusion to the secular variation is correlated with that of tangential ...

Geomagnetic secular variation impulses
Nature, 1984The secular variation of the Earth's internal magnetic field changes on time scales of the order of a year. Such impulses occurred in 1969 and probably in 1913; they provide constraints on deep mantle conductivity, which appears to be rather low, and on the motions of the top of the fluid core, which are probably dominated by westward drift.
