Regarding the correlations between negative SST
and rainfall erosive variables, it is possible to observe that
the correlations were significant and negative, meaning
that during SST negative oscillation (La-Niña episodes),
there was a reduced number of rainfall events, rainfall depth
and rainfall erosive power. Pearson’s coefficients were more
significant for the MR, so the number of variables were
highly significant which means the La-Niña episodes have
greater influence on MR rainfall behavior than on PCV. In
addition, monthly values of EI30 were not significant in
PCV under SST negative.
