The observation of El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) impact on Sea Surface Temperature (SST) reveals some influence on Indonesian water. The data used is SST of NOAA-Pathfinder satellite dataset. Data of ENSO represent by Multivariate ENSO Index, while data of IOD represent by IOD Index. Influence of ENSO and IOD on SST variability in Indonesia is calculating by using empirical orthogonal functions (EOF) analysis. The result show SST in Indonesian water such as Arafura sea, Banda sea, Maluku sea, Java sea, Natuna sea and Makasar strait is mostly correlated to ENSO and IOD phenomenon (Bambang,2010).
This study aims to present the variability of rainfall over the Indochina, and presents
its relation to the SST forcing particularly in the Pacific Ocean. The data analysis was
employed for the purposes as the preliminarily for studying further.
