【 摘 要 】

The differences of altimetry in the Pacific Ocean and the Indian Ocean causes the Indonesia Throughflow or commonly called ITF. The altimerty will have variation when the ENSO (El Nino Southern Oscilation) occur. The altimetry data from AVISO is used to find out how much the influence of ENSO to variations of that indicator in particular the altimetry difference between the western Pacific Ocean to the eastern Indian Ocean. When El Nino occured, the altimetry in the western Pacific Ocean will be lower than the altimetry of eastern Indian Ocean while the opposite condition occurs when the La Nina happened that the differences of altimetry in western Pacific Ocean higher than the altimetry in eastern Indian Ocean. These differences will affect the transport of ITF.
