Rainfall in Azul and its relationship with the phenomenon el Niño Southern Oscillation (ENSO)
The aim of this paper was to verify whether there is a correlation between rainfall conditions that occurred in Azul, Buenos Aires (Lat 36°45' S; 59°57' W and Long altitude 137 m), between 1950 - 2015, and thermal anomalies generated in ENSO episodes in its warm phases - El Niño (EN) a...
