Abstract

A fractal analysis of rainfall events registered in Baja California was carried out. Rainfall data from 92 climatological stations distributed along the studied region with at least 30 years of records were used. By studying rainfall series patterns, Hurst exponent values were obtained. The rescalated range method (R/S), box-counting method and the Multifractal Detrended Fluctuation Analysis (MF-DFA) were used, having as a result the Hurst exponent values for different time scales (entire record, 25, 10, and 5 years scales). Data showed that the daily rainfall series tended to present a persistent pattern. The analysis from the Hurst exponent on the previously mentioned time scales showed that, at a lesser time scale, their values increase; thus, the series tended to present a stronger persistent behavior.
