【摘要】

：

基于考虑根茎影响的近岸植物消波实验,对边界层的最大剪切力特性进行了研究.利用前人提出的规则波下含植物水流的边界层流速计算公式,探究了单独根和根茎组合两种植物模型的边界层最大剪切力特性,分析了两种模型的剪切力的沿程变化、植物对剪切力衰减特性的影响,拟合了衰减系数的公式.研究表明,波浪在通过植物带时,剪切力会出现一定幅度增大,随后逐渐降低.植物对剪切力的消减效果随入射波高的增大而增大,且茎有助于根群对边界层最大剪切力的消减作用,其消减系数的范围为0.06～0.61,拟合的公式更加适用于水深较浅的情况.

Oceanic crustal structure and tectonic origin of the southern Kyushu-Palau Ridge in the Philippine S

A new high-resolution velocity model of the southern Kyushu-Palau Ridge (KPR) was derived from an active-source wide-angle seismic reflection/refraction profile. The result shows that the KPR crust can be divided into the upper crust with the P-wave veloc

季风转换期印度洋经向热输运的年际变异及其机理

本文采用SODA3.4.2再分析数据和POP2海洋模式研究了季风转换期间(春季和秋季)热带印度洋经向热输运异常(Meridional?Heat?Transport?Anomaly,?MHTA)的年际变异特征.春季MHTA存在两个主要模态,即一致模态和辐合辐散模态:一致模态表现为热带印度洋上层一致的向北输运,受热带印度洋海温一致模相关的赤道反对称风场(赤道以北/南为东北风/西北风异常)调控;辐合辐散模态则呈现关于赤道对称的表层辐散次表层辐合特征,受控于赤道以南的热带西南印度洋和副热带东南印度洋海温偶极子.然

台湾海峡有效波高的SWAN模式与ERA-Interim数据对比分析

有效波高是描述海浪的关键参数.欧洲中期天气预报中心(ECMWF)提供的ERA-Interim再分析数据提供了全球海浪的有效波高,本文选取该数据在台湾海峡2013年3月份的有效波高结果,分别与浮标观测数据以及海浪数值模式SWAN?(Simulating?Waves?Nearshore)的数值模拟结果相对比,来分析其预报效果.结果显示:在浮标点,ERA-Interim数据和SWAN模拟浪高数据与浮标浪高数据的时间相关系数分别为0.94和0.98,ERA-Interim数据的浪高均值约为浮标的51％,为SWAN

离岸流灾害水动力学过程的数值模拟研究

离岸流是近岸流的重要组成部分,当波浪受到特殊海滩地形的影响,会形成一股沿着离岸方向运动的高速水流,能够迅速将人带离海岸,对海滨安全造成威胁.为了深入探究离岸流的形成机理及水动力学特性,本文基于二阶Stokes波浪理论,采用了更为光滑的变截面沙坝模型,通过流体体积法捕捉自由液面,对离岸流进行三维数值模拟探究.本文重点分析了离岸流产生时流场的瞬时速度、时均速度、压强等不同参量的分布规律,结果显示在沙坝和海岸线之间,有一对方向相反的水循环体系;对比不同流层离岸流的速度,了解到波浪与离岸流的耦合作用;并探究了入射
