| Zusammenfassung |
| The orthogonal field components from global INTERMAGNET magnetometer
stations are studied via multifractal detrended fluctuation analysis
to determine whether there are clear and consistent regional
patterns in the behavior of the fluctuations. There are three
distinct scaling regimes in the qth-order fluctuation function for
each of the 24 stations studied covering Southwest North America,
Northeast North America, Central Europe, Northern Europe,
Australasia and Asia. There is a consistent break point at time
scale around 23 h for all stations. The scaling exponents of the
second-order fluctuation functions reflect the regional character of
the stations, and can be used for station classification, and for
possible regional models. |
