Anomalous winter rainfalls in central Chile seem to be closely linked to the El Nino-Southern Oscillation (ENSO) system. Actually, documentary data on floods and heavy rainfall episodes in the area during the last few centuries have been previously used in the preparation of a chronology of El Nino events in the past. In the present work, we revised three chronological sequences of climatic anomalies in central Chile and we intent to document a year-to-year chronology of the main rainfall excess during the XVI to XIX centuries. The comparison between this synthetical chronology of rainy years in central Chile and the chronology of the regional El Nino events, or the global ENSO events, shows that available data for the XVI, XVII and XVIII centuries, which may prove not to be complete or precise enough, do not support a close correlation with ENSO/El Nino events, and/or that it is only after the beginning of the XIXth century (1817) that the correlation between both phenomena can be fully assessed. These findings suggest that more historical studies be focused on pre-XIXth century El Nino events. Such studies are necessary 1) to establish the chronology of manifestations of this recurrent anomaly, and 2) to check if, during the last few centuries, various modes of the ENSO system, possibly related to the Little Ice Age climatic variation, have been operating.
