THE CHANGE OF SEA SURFACE HEIGHT ANOMALY (SSHA) IN THE INDONESIAN THROUGHFLOW IN THE EASTERN INDONESIAN WATERS

Sea level differences and sea level change is one cause of Indonesian Throughflow that the mass flow of seawater from the Pacific Ocean to the Indian Ocean. So the research will examine the changes in Sea Surface Height Anomaly (SSHA) on Indonesian Throughflow strip in the eastern Indonesia water...

INSTITUT TEKNOLOGI BANDUNG https://digilib.itb.ac.id/gdl/view/44794 Sea level differences and sea level change is one cause of Indonesian Throughflow that the mass flow of seawater from the Pacific Ocean to the Indian Ocean. So the research will examine the changes in Sea Surface Height Anomaly (SSHA) on Indonesian Throughflow strip in the eastern Indonesia waters, seen from the semi-annual variations, seasonal, inter-annual and decadal (period 8-12 years). The data used is Sea Surface Height Anomaly (SSHA) monthly result of a combination of several satellite altimetry from AVISO. The range of data used is 23 years from January 1993 to December 2015. Data were processed in Hovmöller charts, energy spectrum, and climatological charts (monthly average). Based on the results of the study, there are significant seasonal variations to changes SSHA. During west monsoon (December to February), increase SSHA 5 cm to 15 cm in the study area. East monsoon (June to August) decrease SSHA between 0 cm to -10 cm. Semiannual variation SSHA is so small that the effect is hardly noticeable. Inter-annual variations SSHA influenced by ENSO and DM. During strong El Niño and DM (+) in 1997- 1998 decrease SSHA from -10 cm to -15 cm. During strong La Niña in 2010 – 2011 increase SSHA 5 cm to 7.5 cm than the average SSHA during west monsoon. In addition there are decadal variations (period 8-12 years) changes SSHA with a smaller influence. The results of Hovmöller charts shows that the influence of Inter-annual variations and decadal variations (period 8-12 years) can strengthen or weaken the effect of seasonal variations to changes SSHA. During mild or weak El Niño (La Niña), it will increase the impact of east monsoon (west monsoon) and decrease the impact of west monsoon (east monsoon) to changes SSHA in eastern Indonesian waters. text
