| Outline of Final Research Achievements |
Coastal upwelling along the southwestern coasts of Sumatra and Java in Indonesia can have an impact on occurrence of Indian Ocean Dipole (IOD) phenomenon. Using sea level data along the coasts of Sumatra and Java, we investigated the coastal upwelling signal that is linked to local sea surface temperature (SST) variability.
We found that coastal upwelling events that occurred during May-August were associated with local SST cooling. The horizontal distribution of the SST cooling was analogous with annual-mean SST, suggesting the importance of coastal upwelling in forming the climatic conditions of the southeastern tropical Indian Ocean.
