Indonesia's climate is dominated by the equatorial monsoon system, and has been linked to El Nino-Southern Oscillation (ENSO) events that often result in extensive droughts and floods over the Indonesian archipelago. In this study we investigate ENSO-related signals in a tree-ring delta O-18 record (1900-2007) of Javanese teak. Our results reveal a clear influence of Warm Pool (central Pacific) El Nino events on Javanese tree-ring delta O-18, and no clear signal of Cold Tongue (eastern Pacific) El Nino events. These results are consistent with the distinct impacts of the two ENSO flavors on Javanese precipitation, and illustrate the importance of considering ENSO flavors when interpreting palaeoclimate proxy records in the tropics, as well as the potential of palaeoclimate proxy records from appropriately selected tropical regions for reconstructing past variability of. ENSO flavors.
