Other Abstract本文采用POMPrinceton Ocean Model)模式,结合多波束测量得到的高分辨率地形数据,通过网格嵌套分级计算,得到了南海北部琼西南海域近40km2 研究区内的水平网格分辨率达200 m的海底流场。通过数值试验,确定了内嵌模型的最佳侧面开边界条件。计算结果表明,本文所提出超高水平分辨率嵌套模式能够模拟复杂海洋地形上的余流特征。研究证明,本文为模拟开边界小区域海洋三维流场的提供了一种较为快速、准确的方法。该方法的水平分辨率是目前国际上流行的高分辨率的9倍,也可用于开边界小区域物理海洋环境的数值模拟。; With Princeton Ocean Model, a model with horizontal resolution of about 200 m is developed in this paper to simulate the bottom current field of the small study area that locates in the north of South China Seas. The grid-nesting technique is used twice in this model with the high-resolution bathymetry data measured by multi-beam equipments. The lateral open boundary conditions of the nested model are selected by numerical experiments. It is proved that this ultra-high resolution model is able to simulate the residual current of the area with complex ocean topography and is a quick and accurate way to get three-dimensional high-resolution ocean current field of small sea area with open boundaries. The resolution is nine times as high as international advanced level. The model developed here is also applicable for researches on small scale ocean environment.
