Repeat-station surveys: implications from chaos and ergodicity of the recent geomagnetic field
Magnetic repeat stations Chaos Ergodicity
<
2015/8/18
The present geomagnetic field is chaotic and ergodic: chaotic because it can no longer be predicted beyond around 6 years; and ergodic in the sense that time averages correspond to phase-space average...
