然而对于研究海洋的艰巨性决定了一般的观测手段只能在很小的区域内获取很少有用信息，很难全面准确的认识海洋。
因此，相关方面专家学者开始尝试建立多种海洋模型，模拟出与真实海洋较近似的运行状态，以此提供更便捷的方式帮助人们认识海洋。
本文在总结国内外相关研究现状的基础上，分析当前海洋模型的研究成果和进展，重点选出ROMS海洋模型，FVCOM海洋模型和HYCOM海洋模型这三类模型，并通过实验深入探究三种模型的模拟效果。
主要工作如下：1）学习模型：通过对这三种海洋模型的简单介绍来认识这三种海洋模型的特点和应用区域；2）数据分析：先对比分析由海龟监测的海洋温度数据与ROMS模型模拟的海洋温度数据对比分析，再引入FVCOM海洋模型与HYCOM海洋模型，与ROMS海洋模型模拟的结果进行对比；具体实施方法是在Linux操作系统下利用Python语言作为编程工具进行对比分析的；3）发现规律：通过三种模型的对比分析，探究ROMS海洋模型的优缺点，发现ROMS在温度跃迁层的出现的误差较大；4）海洋模型的优化：通过重新设置模型边界条件和使用更准确的海洋地形数据对ROMS海洋模型进行优化，以提高ROMS海洋模型的海洋温度模拟能力。
运用新版FVCOM，对FVCOM模型提出优化。

However, the difficulty of the study of the ocean determines that the general observation means can only get very little useful information in a very small area and it is difficult to fully understand the marine. So the marine researchers try to establish ocean models to simulate the real operation of the ocean, in order to help people understand and develop the ocean better.This article aims to analyze and summarize three of these models-Regional Ocean Model System, Finite V olume Coastal Ocean Model and Hybrid Coordinate Oceanic Circulation Model. Mainly consisted of followings: 1) Understanding models. Give a brief introduce of three models about the characteristics and application area. 2) Data comparison. Firstly, compare temperature ROMS simulated and the ones from SRDL sensors binding on turtles. Then FVCOM and HYCOM are introduced, and ROMS is compared with these two ocean models. The concrete implementation method is under the Linux operating system using Python language as a programming tool for comparative analysis.3) Find regular rules. Through the comparative analysis of the three models, analyze the advantages and disadvantages of ROMS. 4) Optimization of ocean model. Reset the boundary of ROMS and use more accurate ocean terrain data to improve ocean temperature simulation capability of ROMS. Using new version optimizes FVCOM model.Key words: Ocean model; ROMS; FVCOM; HYCOM; Data comparison目录1绪论 (1)1.1 问题的提出 (1)1.2 海洋模型的发展现状 (2)1.3 研究内容及方法 (4)1.4 课题的研究意义 (5)2海洋模型简介 (6)2.1 ROMS海洋模型简介 (6)2.2 FVCOM海洋模型简介 (9)2.3 HYCOM海洋模型简介 (14)3海洋模型温度与观测温度对比 (16)3.1 数据来源与处理 (16)3.2 实际监测数据分析 (19)3.3 对比分析ROMS模型模拟数据与实际监测数据 (25)3.4 引入FVCOM模型和HYCOM模型 (37)3.5 本章小结 (44)4海洋模型优化 (46)4.1 ROMS海洋模型优化 (46)4.2 FVCOM海洋模型优化 (47)5结论与展望 (50)5.1 结论 (50)5.2 展望 (51)致谢 (53)参考文献 (53)攻读硕士学位期间从事科学研究及发表论文情况 (58)Contents1 Introduction (1)1.1 Propose the problem (1)1.2 The development status of ocean model (2)1.3 Research contents and methods (4)1.4 Research significance (5)2 Ocean model introduction (6)2.1 ROMS introduction (6)2.2 FVCOM introduction (9)2.3 HYCOM introduction (14)3 Comparison of ocean model temperature and observed temperature (16)3.1 Data sources and processing (16)3.2 Analysis of actual monitoring data (19)3.3 Comparison of ROMS data and observed data (25)3.4 The introduction of FVCOM and HYCOM (37)3.5 Summary (44)4 Ocean model optimization (46)4.1 ROMS optimization (46)4.1 FVCOM optimization (47)5 Conclusion and prospect (50)5.1 Conclusion (50)5.2 Prospect (51)Acknowledgement (53)References (53)Scientific research and published papers (58)1绪论1.1 问题的提出从太空的角度观看现在的地球，其实是一个“水球”，海洋面积三亿六千万平方千米，占地球表面积的比例高达71%，空间广阔，资源丰厚。
