Résumé
"Homogenization analysis of rainfall series of 210 rainfall stations from the coast, the highlands, and the eastern part of Ecuador allows to study for the first time, over a period of 30 years, the influence of El Niño on the annual precipitation in Ecuador. This influence is analyzed and quantified using several statistical and numerical techniques that point out the relation between annual precipitation and El Niño. Synthesis of the results obtained using the different methods allows the division of Ecuador into three regions. The first region where the influence of El Niño over the annual precipitation is very high, the second region where this influence is not significant and an intermediate zone where its influence varies from one event to the other."
