The Regional Oceanic Modeling System ROMS is applied in a nested configuration with realistic forcing to the Celebes Sea to analyze the variability in semidiurnal sirculation. The dynamic and physical processes that trigger these sirculation events are still less well understood. In the present study we proposed a variablity of the sirculation event using a numerical model of the Regional Ocean Modeling System ROMS. Model validations showed a high correlation of SST climatology between the model and the NOAA AVHRR satellite data. Moreover, velocity fields of the Indonesian Throughflow ITF Celebes Sea in Sangihe Chain Islands was well reproduced by proposed model, revealing an intensification of the flow centered near 100 m depth, which is in good agreement with the observation data. Based on the results of the research, the maximum surface layer current in the west season December Februar ranges 0.4-0.9 m / s, and the minimum in the transition period II November reaches only 0.2 m / s. While the maximum current of the thermocline layer was found in August with a range of 0.6 0.8 m / s and the minimum in January of only reaching 0.3 m / s. In the bottom layer the maximum current thermocline is found in February with an average of about 0.2 m/s and the average minimum flow occurs from September to November at about 0.1 m/s. Average temperatures on the surface layer in the Sulawesi Sea range from 26-31oC with the highest lowest temperature occurring in December August of 310C 260C. The thermocline layer ranges from 18-22.50C with the highest lowest temperature occurring in February August of 22.50C 180C. While in the lower layers of thermocline ranged between 10.8 12.2C with the highest lowest temperature occurred in January August of 12.20C 10.80C. The average salinity on the surface layer in the Sulawesi Sea ranges from 33 to 34.4 psu with the highest lowest temperature occurring in September October April of 33 psu 34.4 psu. Haloklin layers range from 34.55 to 34.6 psu with the highest lowest temperatures present each month. While in the lower layers of thermocline ranges from 34.55 to 34.65 psu with the highest lowest temperature occurs in each month. Key words: Variability, ITF, ROMS-AGRIF, Celebes Sea.
