Índice padronizado de precipitação aplicado às condições de seca no Estado do Espírito Santo Standardized precipitation index applied to drought conditions of the State of Espírito... by Gabriel C. Blain, José R. M. Pezzopane, José E. M. Pezzopane, Robson Bonomo

“…Using the autocorrelation function and the cross-correlation function, it was possible to verify that the main characteristic of the monthly SPI series is high temporal variability of its values. This indicates that, within a same region, extreme dry months may be preceded and/or followed by normal or wet months, and different drought condition can be observed, at the same period, among the five analyzed regions.…”

Searching for Functional Simplicity of Stormflow Generation by Hamed Sharif, Ali A. Ameli

“…The functional simplicity of simple catchments is further explored using spectral (coherency) analysis, which indicates the level of synchronicity between daily scale precipitation and streamflow time‐series. Simple catchments exhibit a strong coherency value at high frequencies, resembling the dynamic of a nearly Linear Time‐Invariant system. …”
