Investigating the temporal variation of the scaling behavior in rainfall data measured in central Argentina by means of detrended fluctuation analysis

► Time variant scaling behavior in rainfall series in Argentina from 1860 to 2006 by the DFA is revealed. ► Eastern stations show visible crossovers between persistent and random behavior. ► North-western stations are characterized by random behavior approximately at any time. ► One station (i.e. Corrientes) shows several crossovers from persistent to random behavior. ► The obtained results can be interpreted in the context of the climatological conditions of Central Argentina.
