以數值模式為基礎探討颱風季的波浪潛能
Estimate the Potential of Wave Energy in Typhoon Seasons Using Numerical Models
摘要
隨著全球氣候暖化的影響，平均溫度持續升高，多元發展再生能源為必要且迫切之需求。海洋表面的波浪是最具規模也最有潛力的再生性海洋能源與新興再生能源。過去對於波浪能的估算大多受限於近岸現地波浪觀測儀器，僅能估算沿海海域的波浪潛能發展岸式波浪發電機。若要發展離岸式波浪發電，需準確的推算外海的波浪分布與波浪能潛勢。在夏秋之際，臺灣周邊海域平均每年約有4～5個熱帶氣旋經過，其高強度風場在暴風半徑內部及外圍海域可提供高強度的波浪能。本研究將透過強化颱風風場結構（Holland wind vortex）之再分析風場資料，來驅動第三代波浪模式（WAVEWATCH III），分析與檢視臺灣周邊海域在過去30年間颱風所引起之波浪特性以及評估期波能密度，作為未來離岸波浪能發展之參考。

As the global mean temperature continuously raising, developments of renewable energy are essential and imperative. Ocean surface wave energy is the largest of the renewable marine energy resources, and wave energy was shown with high potential as an emerging industry of renewable energy. However, due to the limitations of in-situ observation, accurately understanding the spatial distribution of wave state offshore is always a challenge regarding to the developments and deploys of the offshore wave generator. In addition, there are 4 ~ 5 tropical cyclones passing Taiwan and the surrounding seas each year. The strong wind of tropical cyclones generates high wave heights, which enhance the potential of offshore wave energy. In this study, we aim to estimate the potential wave energy using a high-resolution wave model (WAVEWATCH III) around Taiwan. The wave model is forced by the enhanced wind field, which combined the Holland Wind Vortex and re-analysis wind, to accurately simulate the pattern of wave height and the wave power density under the influence of tropical cyclones for the past 30 years (1993 ~ 2023).
