North East Atlantic ROMS Hydrodynamic Model

The ROMS (Regional Ocean Modeling System) hydrodynamic model is run for a domain that covers the Irish waters in the northeast Atlantic. The model has a mean horizontal resolution of 1.9 km and 40 terrain-following vertical layers. The system produces a best estimate of the ocean state once a week and also a daily 3-day forecast. Parameters modeled include: ocean temperature and salinity, sea level, and ocean currents. In addition, two models with a horizontal resolution of 200 - 250m are nested within the larger model to give 3 day forecasts of ocean state for the greater Galway Bay area (Connemara model) and the southwest of Ireland (Bantry Bay model). The ocean forecasts are generated on a 'best endeavors' basis and should not be used for safety critical applications. 7-day forecasts are generated for research purposes and for comparison with measured data. NCEP GFS atmospheric forcing is used and the model is nested within the MERCATOR North Atlantic model. The Marine Institute does not guarantee to make model output available on its web site.ROMS（区域海洋模式系统，Regional Ocean Modeling System）水动力模式针对覆盖东北大西洋爱尔兰海域的计算域开展数值模拟。该模式的水平平均分辨率为1.9 km，共设置40层地形追随垂直分层。该系统每周可生成一次海洋状态最优估计结果，同时每日发布为期3天的海洋预报。模拟参数涵盖海洋温度、盐度、海平面高度及海流。此外，本研究嵌套了两个水平分辨率为200~250 m的子模式，分别针对戈尔韦湾周边海域（康尼马拉模式）以及爱尔兰西南部地区（班特里湾模式）生成为期3天的海洋状态预报。本次海洋预报基于“尽最大努力”原则生成，不得用于安全关键应用。7天海洋预报仅供科研用途以及与实测数据对比分析。模式采用NCEP GFS大气强迫场，并嵌套于MERCATOR北大西洋模式之中。爱尔兰海洋研究所不保证可在其官方网站上提供该模式的输出结果。
