Spectral analysis of the geomagnetic field time series with the discreteness of 60 s (Intermagnet data) and a duration of, for example, 1 year (31×106 s) yields an average-annual amplitude spectrum over periods from approximately 500 s to 5×106 s. The spectrum consists of the continuous part (contin...
