本文以美國普林斯頓海洋模式 POM (Princeton Ocean Model)為基礎,建置台灣環島海域三維海潮流模擬系統,以巢狀網格縮小計算範圍至台灣南部之南灣海域。將格網間距調整至500m(約1/200°),利用高解析度之計算技巧來模擬南灣海域潮流與溫度的變化,同時模擬呂宋海峽之內潮機制,即正壓潮轉為斜壓潮(內潮)能量(barotropic to baroclinic tidal energy conversion)。根據模擬結果,進一步的探討南灣海域湧升流(upwelling)冷水出現之機制。由平面及垂直剖面之溫度與潮流模擬結果可知,南灣海域溫降現象於大潮期間較為顯著,在退潮時,南灣海域的潮流流速則逐漸的增強,同時當地潮流因受到模擬區域內海底山以及恆春海脊地形的影響,在灣內衍生逆時針渦流。本文斜壓潮能量通率計算結果顯示,在恆春海脊北端有明顯強烈向西傳遞的斜壓潮能量通率產生,且此能量通量在傳遞至南灣海域後繼續往台灣西南海域移動,在南灣海域內部產生擾動,導致深海冷水湧升至南灣淺水區,造成南灣海域海水溫度突降的現象。與沒有黑潮時的斜壓潮能量通率相比較,在恆春海脊北端產生的斜壓潮能量通率有減弱趨勢,且會影響南灣沿岸溫度變化。
In this study, a three-dimensional ocean current model around Taiwan is developed using POM (Princeton Ocean Model). The model was applied to construct the three-dimensional model for simulating ocean current around Taiwan coastal waters. The nested domain was adopted to narrow the computational region to the southernmost coastal waters of Nanwan Bay at Taiwan. A higher-resolution model with spatial grid of 500m(1/200 degree), was used to simulate the distribution of current and temperature in the Nanwan Bay and baroclinic tidal energy flux in the Luzon Strait. The barotropic-to-baroclinic (bt-to-bc) tidal energy conversion rate and bc tidal energy fluxes were further analyzed and was used to locate the generation site of internal tides in the Luzon Strait. From simulation results, we further study the cold water of upwelling at Nanwan Bay. The results show that the sudden temperature drops occurred more significantly during spring tides at Nanwan Bay. Inside the Bay, the current forms a counter clockwise vortex because of the topographic effect during the ebb tide. The results
of the baroclinic tidal energy flux show that the baroclinic tidal is generated from the eastern flank of Heng-Chun Ridge, and there is a strong energy flux area which seems to
be a source of the baroclinic tidal westward propagating into the Bay. The upwelling of cold water due to the baroclinic tidal propagating from the Heng-Chun Ridge causes the temperature drops. Comparing with the baroclinic tidal energy flux without the Kuroshio’s influence, the energy flux can reduce the temperature variations.
