A fractal temporal analysis of moderate and intense magnetic storms

Abstract In this paper we have studied, in terms of a fractal analysis, the time distribution of Dst peaks associated with Storm Sudden Commencements (SSCs), during the years 1957 and 1978. To ensure a complete set of data, we considered only moderate and strong storms (Dst peaks Similar results have been observed for the different sets of data. In all the cases a strong clustering has been determined for ranges of scale series between 1 month and 1 yr, showing a non-random contribution in the generation of storms with sudden commencements, which are usually associated to a stochastic behavior.
