“…Multifractal properties of the geomagnetic storm were studied using various methods [19]. The generalized fractal dimension of the total magnetic field having peaks during the main phase of magnetic disturbances was used in [20] noting that fractal dimension changes demonstrate more details of solar activity in comparison to the Dst-index variations. Alberti et al [21], using the multiscale generalized fractal dimensions in the SYM-H geomagnetic index analysis, showed a more steady behaviour at the timescales related to the solar wind changeability and to the nonlinear magnetospheric response to solar wind variations.…”

We are concerned with the time series resulting from the computed local horizontal geoelectric field, obtained with the aid of a 1-D layered Earth model based on local geomagnetic field measurements, for the full solar magnetic cycle of 1996–2019, covering the two consecutive solar activity cycles 23 and 24. To our best knowledge, for the first time, the roughness of severe geomagnetic storms is considered by using a monofractal time series analysis of the Earth electric field. We show that during severe geomagnetic storms the Katz fractal dimension of the geoelectric field grows rapidly.

“…The 2D wavelet transform modulus maxima lines WTMM is a signal processing technique introduced by Arneodo and his collaborators in image processing [26] [27] .It was applied in medical domain as a tool to detect cancer of mammograms and in image processing [25]. The flow chart of this method is detailed in figure 14.…”

“…The WTMM was used in various domains to resolve many scientific problems [24] [25]. A generalized wavelet transform modulus maxima lines WTMM in the 2D domain are used by many researchers to establish physicals problems [25] [26]. The wavelet transform has been applied in seismic image processing; Miao and Moon [27] have published a paper on the analysis of seismic data using the wavelet transform.…”
