Numerical simulation of tidal wave in the sea area around Taiwan Island and the expansion of Minjiang river diluted water in winter

Abstract

本文首先验证了三维POM(PrincetonOceanModel)模式在环台湾岛海域潮汐潮流模拟应用中的有效性,接着利用实测和经分析的资料,应用该模式对闽江径流量、海表面风场进行分析,以期了解冬季闽江入海冲淡水的特征和运移的动力机制。 潮波模拟区域选择环台湾岛海域,包括东海南部、台湾海峡、南海东北部海区、台湾岛以东的大洋区以及吕宋海峡。通过潮汐、潮流数值计算的模拟结果与环台湾岛海域38个验潮站实测资料的调和分析结果、潮汐表的天文潮资料、ADCP实测海流资料等的比较分析,以验证POM模式在环台湾岛海域数值模拟中的模拟效果。验证结果显示,M2分潮振幅和迟角平均绝对误差分别为5.8cm和5.1°,...At first, Three-dimensional model POM(Princeton Ocean Model) was tested for its feasibility and effectiveness in the Numerical simulation for tide and tidal current in the sea area around Taiwan Island,and then by using the field data and the reanalysis monthly mean data,the influence of Minjiang runoff and sea surface wind were analysed in the model,in order to understand the characteristics and ...学位:理学硕士院系专业:海洋与环境学院海洋学系_物理海洋学学号:2005130215
