Spatiotemporal variability of extreme precipitation in Ecuador (1991-2020): Wavelet coherence and non-parametric trend analysis by homogeneous zones
This study analyzes 1991–2020 daily precipitation data across 22 homogeneous zones in Ecuador to reveal significant spatial heterogeneity in extreme rainfall trends and their scale-dependent modulation by ENSO, identifying specific zones with upward trends and abrupt climate shifts that are critical for disaster risk management.
