Geomagnetic jerks: rapid core field variations and core dynamics
The secular variation of the core field is generally characterized by smooth variations,
sometimes interrupted by abrupt changes, named geomagnetic jerks. The origin of these …

Short timescale core dynamics: theory and observations
Fluid motions in the Earth's core produce changes in the geomagnetic field (secular
variation) and are also an important ingredient in the planet's rotational dynamics. In this …

Ensemble inversion of time‐dependent core flow models
Quasi‐geostrophic core flow models are built from two secular variation models spanning
the periods 1960–2002 and 1997–2008. We rely on an ensemble method to account for the …
