[1] Nonlinearly evolving dynamical systems, such as
space plasmas, generate complex fluctuations in their
output signals that reflect the underlying dynamics. The
non-extensive Tsallis entropy has been proposed as a
measure to investigate the complexity of system dynamics.
We employ this method for analyzing Dst time series. The
results show that Tsallis entropy can effectively detect the
dissimilarity of complexity between the pre-storm activity
and intense magnetic storms (Dst < 150 nT), which is
convenient for space weather applications. Citation: Balasis,
