亞洲邊緣海非線性內波非常活躍,蘇祿海(Sulu Sea)、南海(South China Sea)及安達曼海(Andaman Sea)是其中非線性內波興盛且規模較大的幾個邊緣海。經過多年的研究,我們對蘇祿海及南海的內波已有相當的認識,然而對安達曼海內波的了解卻非常粗淺。規模較大的內波即使在解析度不高的衛星影像中也非常明顯,因此目前可用於研究規模較大內波的免費衛星影像資料非常多。本研究想由現有的免費衛星影像資料中,萃取安達曼海非線性內波的資訊,用於了解非線性內波在安達曼海的空間分布,源區及演化過程。本研究收集了數千餘幅安達曼海域的合成口徑雷達(Synthetic Aperture Radar, SAR)影像及MODIS(Moderate Resolution Imaging Spectroradiometer)等可見光影像。找出內波之波鋒線,彙整成一幅安達曼海的內波分布圖。根據個別的波群,找出安達曼海內波波源可能的位置。再根據內波波源及內波分布圖,來瞭解非線性內波在安達曼海的演化過程,並比較安達曼海內波與蘇祿海內波及南海內波相似與相異之處。
Asian waters are abundant with nonlinear internal waves. Andaman Sea is one of the nonlinear internal wave active marginal seas. We like to know the spatial distribution of internal waves, the generation and evolution of internal waves in the Andaman Sea. Thus, we collected thousands of SAR images and MODIS images in Andaman Sea region. After compiler all of the images we collected, an internal wave distribution map of Andaman Sea was built up. Numerous of internal wave characters in Andaman Sea are identified such as internal wave sources, wave-wave interaction, wave reflection and internal waves generated in Andaman Sea but propagated outward into India Ocean are found and discussed.
