A Study of Generation and Evolution of Nonlinear Internal Wave in the Sulu Sea Using SAR / 利用SAR衛星影像研究SULUSEA非線性內波之發源及演變

碩士 / 國立海洋大學 / 海洋科學系 / 89 / The large-scaled internal wave phenomenon in the Sulu Sea in Philippine is prominent. In the early research, only Apel et al. (1985) acquired numerous in-situ data in the Sulu Sea, analyzed less low-resolution visible-wavelength imagery and applied the KdV equation to carry out the numerical simulation. However, few papers had been published since then. Recently the spatial and temporal resolution of the spaceborn Synthetic Aperture Radar (SAR) have largely promoted. From Centre for Remote Imaging, Sensing and Processing (CRISP) web site, http://crisp.nus.edu.sg , we first searched about four hundred SAR images captured during 1996 and 2001 by the ERS-1/2 satellite over the Sulu Sea. In order to investigate the generation and evolution of nonlinear internal wave in the Sulu Sea in Philippine, we have plot some multi-layer synthetic figures including SAR images and sea bottom topography by seasons and months, so they are easy to study and reveal some features. It is found that most of the internal waves are generated from the Sulu archipelago in southeast of the Sulu Sea and travels toward the Palawan Island. Some sources are near the Pearl Bank and Doc Can Island instead of the underwater shallow sill between the two islands. Another source also have been found near the Pandu Can Island about sixty five kilometers northeast from the Doc Can Island. When the water depth becomes shallow to about two hundred meters, the refraction effect is significant.
