Time statistics of extreme events (EEs) in one-dimensional discrete Salerno
lattices is investigated numerically. We show that the dependence of the mean
return time of EEs on the amplitude threshold can be used as a criterion to
differentiate between various dynamical regimes of the extreme events. Also,
we found that dispersion of points on the time probability distribution curve
can be an indicator of the appearance of EEs in the system, but it has to be
complemented with other statistical measures. The results obtained here can
be used to distinguish between different dynamical regimes and as identifiers
of the EEs existence in the lattice system.
