Geomagnetic jerks in the Swarm Era [PDF]

, 2016
The timely provision of geomagnetic observations as part of the ESA Swarm mission means analysis and modelling can be conducted rapidly and kept up-to-date in a manner not possible before.

The origin of geomagnetic jerks

Nature, 2002
Geomagnetic jerks, which in the second half of the twentieth century occurred in 1969 (refs 1, 2), 1978 (refs 3, 4), 1991 (ref. 5) and 1999 (ref. 6), are abrupt changes in the second time-derivative (secular acceleration) of the Earth's magnetic field.

Chandler wobble and geomagnetic jerks

Physics of the Earth and Planetary Interiors, 2001
Abstract Some features of the polar motion may be due to core–mantle coupling, but no convincing quantitative mechanism has yet been proposed. Considering phase jumps in the Chandler wobble and noticing their correlation with geomagnetic jerks [J. Geophys. Res.

Free core nutation and geomagnetic jerks

Journal of Geodynamics, 2013
Abstract Variations in free core nutation (FCN) are associated with different processes in the Earth's fluid core and core–mantle coupling. The same processes are generally caused the variations in the geomagnetic field (GMF) particularly the geomagnetic jerks (GMJs), which are rapid changes in GMF secular variations.

Localized analysis of polar geomagnetic jerks

Tectonophysics, 2013
Abstract A new method is introduced to find the relatively sudden temporal changes or jerks of the geomagnetic field over the polar regions. Geomagnetic jerk events during the 20th century have mostly been identified from direct measurements at mid-latitude geomagnetic observatories.
