| Zusammenfassung |
| Indonesia's climate is dominated by the equatorial monsoon system, and has
been linked to El Niño-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 δ18O
record (1900–2007) of Javanese teak. Our results reveal a clear influence of
Warm Pool (central Pacific) El Niño events on Javanese tree-ring
δ18O, and no clear signal of Cold Tongue (eastern Pacific) El
Niño 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. |
