摘要：

In this work we study the complexity of monthly rainfall temporal series recorded from 1962 to 2012, at 69 meteorological stations in Paraiba state, northeastern Brazil. We use the Modified Multiscale Entropy Method (MMSE) suitable for short time series and analyze rainfall regularity over a wide range of temporal scales from 1 month to 1 year. By comparing the results for stations across Paraiba state and performing a statistical significance test, we distinguish rainfall regime in the inland semiarid Sertão and Borborema regions from the transition inland Agreste, and coastal, tropical humid Mata regions. Our work represents a contribution to establishing the use of multiscale approach with methods from information theory in climatological studies. © 2021
