Spatiotemporal Characteristics of Geomagnetic Variations in the Range of Jerks

The authors performed wavelet analysis of the average monthly changes in the values of the time series of the geomagnetic field, as well as correlation analysis of the wavelet coefficients with fixed values of the scale factor for three European, Asian and North American magnetic observatories. The results suggest that the processes related to the phenomenon of jerks have a morphologically complex character and dynamics that differ significantly for different time scales and probably represent the consequences of a set of phenomena that are similar in nature, but different.
