【 摘 要 】

Indonesian Seas have an important role on the sea-air interaction in Indo-Pacific region. Makassar Strait is located in the center of Indonesian Seas and part of Indonesian Throughflow (ITF), which has been influenced due to the coupled ocean-atmosphere phenomenon in Pacific and Indian Oceans, such as monsoon, El-Ni?o Southern Oscillation (ENSO), and Indian Ocean Dipole (IOD). The temporal and spatial variation of surface heat flux in Makassar Strait has been evaluated using the multi satellite dataset from 1984-2009. The remote sensing data with resolution of 1° × 1° obtained from Objectively Analyzed air-sea Fluxes (OAFlux) produced by Woods Hole Oceanographic Institution (WHOI). The results show that there is a seasonal fluctuation of surface heat flux related to the wind monsoon. The variation of the shortwave radiation and latent heat flux give a large contribution to the net surface heat flux that associated with ENSO and IOD events. In Makassar Strait, the variation of shortwave radiation and sea surface temperature (SST) is in a good agreement with the El-Ni?o/La-Ni?a events. There is a time lag between surface heat fluxes with the ENSO events.
