Short summary

We investigate the factors that determine the longer lead ENSO predictability in the 1980-2012 period. We compare different versions of the prediction model using some variables that contain tropical or extratropical information.We observe that where tropical predictors are used the prediction reproduces only the equatorial characteristics of the warming (cooling). However, where extratropical predictors are included, the predictions are able to simulate the absorbed warming in the SPCZ.
