| Interannual to decadal changes in Indonesian throughflow(ITF) transport are investigated using long integrationsof two different coupled models. Results from a 300-yearintegration of the NCAR Parallel Climate Model (PCM) areexamined along with results from a 200-year integrationof the ECHAM-ORCA coupled GCM (SINTEX). Depth-integratedtransport through the exit passages in the ITF region wascomputed from each integration. Low frequency variationsin the model wind, surface salinity and temperature fieldswere also diagnosed. Composite ENSO variations show thatITF transport in all depth ranges becomes weak during andjust after peak El Nino events, consistent to a certaindegree with observations. Lower frequency variations inITF transport are of the order 1 Sv, and early analysisindicates that in these coupled models low frequencychanges in ITF transport do not significantly impact thePacific/Indian Ocean ocean/atmosphere. |
