چکیده انگلیسی
The objective of this study was to determine the probability of occurrence of wet or dry season events, by means of estimating latitudinal profiles for the association between El Niño Southern-Oscillation and the rain-fall along the west coast of Central and South America. The analysis was performed using multinomial linear regression and multinomial logit regression models. We used monthly time series of the Pacific equatorial sea surface temperature (SST), the Niño 3.4 index, a sea level pressure index (SOI) and rainfall anomalies over a 2.5 Ã 2.5° grid along the west coast of Central and South America, for latitudes starting at 25° N through 45° S, from 1951 to 2011. We defined an ENSO index (NSO) as predictor and rainfall as response. Data was grouped into seasons and then categorized into terciles to construct 3 Ã 3 non-symmetrical three way contingency tables. As results, we generated latitudinal profiles of the predictability (association) of rainfaÃl for the west coast of Central and South America, using the ENSO phases as predictor.
