3D Numerical Simulation of Kuroshio-induced Wake Near Green Island, Taiwan

Oil Spill Sensitivity Analysis of the Coastal Waters of Taiwan Using an Integrated Modelling Approach

“…The Princeton Ocean Model (POM) [6,8,18,27] is a baroclinic model that uses a curvilinear orthogonal grid for the horizontal coordinate (x, y) and a vertical grid for the sigma coordinate, σ. The governing equations of the models are ∂DU ∂x…”

“…Assessments of oil slick risk not only help to better manage emergency plans, minimise economic loss [1,2], and mitigate the impacts of oil spills [3,4] but also support the formulation of emergency plans and the identification of mitigation policies [5]. However, for oil spills that occur in the water adjacent to Taiwan, most research has focused on using different numerical models to hinder particular events [6][7][8][9][10][11][12], analysing marine pollution management [13,14], and satellite observations [15]. Other efforts for better understanding the assessments of oil spills along the Eastern Mediterranean coasts can be found [16,17].…”

“…In this study, several probable oil slicks in Taiwan were simulated over time (12 months) and space (four spill locations in the marine area of each coastal city or county) using an integrated model. The integrated model included the Princeton Ocean Model (POM) [6,8,18] to determine three-dimensional current data and OpenOil (v1.1) [19] to obtain the fate and trajectory of the spilled oil. The percentage risks under the effect of an oil spill were then estimated.…”

Solution of Shallow-Water Equations by a Layer-Integrated Hydrostatic Least-Squares Finite-Element Method

“…Shipboard ADCP-CTD profiling was conducted to investigate the surface patterns, vertical structures, the evolution of the Green Island vortices [22,23]. The ERS-1 SAR images and Moderateresolution Imaging Spectroradiometer (MODIS) satellite images [24][25][26][27], and numerical modelling [28][29][30][31][32] have also been used to study Kuroshio-induced island vortex of Orchid Island and Green Island. Figure 5a shows a composite ERS-1 SAR image of the Kuroshioinduced vortex of Orchid Island and Green Island, taken in one-week intervals, sequentially,…”

“…Kuroshio passes Orchid Island and Green Island off the southeastern coast of Taiwan. Kuroshio-induced Green Island vortices have previously been studied with in-situ measurements [22,23], such as ERS-1 SAR images, moderate-resolution imaging spectroradiometer (MODIS) satellite images [24][25][26][27], and numerical modelling [28][29][30][31][32].…”
