本文采用POM(Princeton 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40km~2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.
Based on the POM (Princeton Ocean Model) model and the high-resolution topographic data obtained from multibeam measurements, the horizontal grid resolution of nearly 40km ~ 2 in the Southwestern South Sea of South China Sea And the submarine flow field up to 200 m was obtained.The optimal lateral open boundary conditions for the embedded model were determined by numerical experiments.The calculation results show that the superhigh resolution nesting mode proposed in this paper can simulate the residual current characteristics of complex ocean topography The research proves that this paper provides a fast and accurate method for simulating the oceanic three-dimensional flow field in a small boundary area.The method has a horizontal resolution of 9 times that of the current high resolution in the world and can also be used to open the boundary Numerical simulation of physical environment of small area.
