El Niño as a predictor of Argentine Andean riverflows

This study aims to contribute to understanding the potentiality of Sea Surface Temperature (SST) as a water-volume predictor of Argentine Andean rivers, especially the SST anomaly over the equatorial Pacific sector (Nño3+4), and to determine the delay of such a potentiality at monthly-to-seasonal sc...
