1、温州近海的潮波精细化数值研究第二章：从地貌、气象、水文三个方面概述了研究区域的基本特征，从潮汐、潮流、余流三个方面对该区域的水文特征有了大致的了解。第三章：对FVCOM数值模型整体进行了较详细的介绍，同时由第二章对研究区域基本特征的了解进行了相应的模型计算配置。第四章：利用收集到的4个验潮站和9个连续观测的实测资料对模拟结果进行了验证，对温州近海潮流潮汐计算结果进行了分析。第五章：总结了温州近海潮流数值模拟的主要结论，阐述了研究过程中的困难和不足，以及对今后工作的展望。关键词：温州近海，潮汐，潮流，FVCOMII万方数据宁波大学硕士学位论文Highresolutionnumericalsimu
