Resumen en inglés | Modeling and forecasting of rainfall is of great importance because it helps to estimate water availability and planning diverse human activities like agriculture. To estimate annual rainfall and monthly temperatures it is common to use probability distributions like the Normal, Lognormal, Gamma and Gumbel distributions. Although these probability distributions have provided the useful forecast predictions needed in planning, these models do not take in consideration the possible influence of the Central Pacific Ocean-atmosphere anomalous oscillations in temperatures that have been called the “El Niño” or ENSO (El Niño Southern Oscillation) event. In this paper, this influence is analyzed with correlation analysis, multiple regression methods and transfer functions or dynamic regression, it was found that at a national level there is an small increment in rainfall after a strong “El Niño” event, in contrast, in the Valle del Yaqui the annual rainfall decreases after the occurrence of a strong “El Niño”. The annual mean of minimum monthly temperatures increases lightly in “El Niño” years and decreases in “La Niña” years |
