| 1 | 西沙群岛礁栖鱼类物种多样性及其食性特征显示文摘通过新的方法(即潜水调查法)调查了西沙群岛浅水区的礁栖鱼类,并从食性角度分析鱼类群落特征及其对水质环境变化的响应。2006年5–6月,对西沙群岛6个岛礁(东岛、永兴岛、羚羊礁、金银岛、华光礁和中建岛)共10个站位的礁栖鱼类种类、数量和长度进行了调查,结合公开资料(FishBase等)确定鱼类食性。共记录到29科71属119种鱼,其中50种是新记录。至此,西沙群岛的鱼类总记录已达到717种。从不同站位来看,永兴岛西的种类数量和Shannon-Wiener多样性指数均最高。多数鱼种分布范围狭小。摄食浮游动物和底栖无脊椎动物的鱼类是优势类群,而草食性、杂食性和食物链顶端食性的鱼类数量和生物量较低,反映出西沙群岛珊瑚礁生态系统整体上健康稳定。永兴岛的杂食性鱼类的数量比例和生物量比例均高于其他岛礁,反映出鱼类群落已对水体富营养化产生响应。 | 高永利 黄晖 练健生 杨剑辉 | 2014 | 生物多样性2014，22，5： | 22 |
| 2 | 与南海西边界流有关的区域海洋学进展显示文摘从动力学角度,回顾了与南海西部主流系及其涡旋研究有关的南海物理海洋学的进展.主要内容涉及南海西边界流漂流浮标观测、西边界流源区涡旋遥感观测、西边界流源区跨陆架交换、涡流相互作用、西边界流年际变化、西边界流区海气相互作用、南海贯穿流等方面的进展.西边界流是一个强流系,其与季节和年际变化相关的结构特征、变率及跟某些动力过程的关联有待研究.在西边界流变率、涡旋环流相互作用、海气过程以及南海贯穿流取得了以下成果:(1)利用漂流浮标观测样本对南海西边界环流进行分析,指出南海西边界表层环流在到达越南中部沿岸后伴随着流幅变窄的同时流速加强;探讨了南海北部环流变化机理,定量诊断南海西边界流北支冬季逆风流产生的动力机制;利用航次数据对18°N断面的经向地转流进行诊断,表明南海西边界流的经向输送年际变化明显;(2)结合航次观测数据,对2003/2004年冬季南海北部2个反气旋涡旋和2007年夏季18°N附近的3个反气旋涡旋进行研究,指出冬季2个涡旋产生后以罗斯贝(Rossby)波速度(约0.1m/s)沿北部陆坡向西南方向传播,并初步揭示了南海西边界环流与夏季3个涡旋的相互作用;南海北部陆架区涡旋西南向传播最大(最大为0.09m/s),而越南以东海域涡动能(EKE)最大,这都说明涡旋活动与南海西边界流存在强的相互作用;(3)发现南海西边界流附近海表面温度(SST)强的季节内振荡特征,进一步研究表明此区域冬季SST季节内变化会使潜热季节内信号减弱20%;(4)探讨了南海贯穿流的长期变化特征以及与整个太平洋环流系统的相互关联. | 王东晓 刘钦燕 谢强 贺志刚 庄伟 舒业强 肖贤俊 宏波 吴湘玉 隋丹丹 | 2013 | 科学通报2013，58，14： | 10 |
| 3 | Progress of regional oceanography study associated with western boundary current in the South China Sea显示文摘Recent progress of physical oceanography in the South China Sea (SCS) associated with the western boundary current (WBC) and eddies is reviewed in this paper. It includes Argo observations of the WBC, eddy detection in the WBC based on satellite images, cross-continental shelf exchange in the WBC, eddy-current interaction, interannual variability of the WBC, air-sea interaction, the SCS throughflow (SCSTF), among others. The WBC in the SCS is strong, and its structure, variability and dynamic processes on seasonal and interannual time scales are yet to be fully understood. In this paper, we summarize progresses on the variability of the WBC, eddy-current interaction, air-sea interaction, and the SCSTF achieved in the past few years. Firstly, using the drifting buoy observations, we point out that the WBC becomes stronger and narrower after it reaches the central Vietnam coast. The possible mechanisms influencing the ocean circulation in the northern SCS are discussed, and the dynamic mechanisms that induce the countercurrent in the region of northern branch of WBC in winter are also studied quantitatively using momentum balance. The geostropic component of the WBC was diagnosed using the ship observation along 18°N, and we found that the WBC changed significantly on interannual time scale. Secondly, using the ship observations, two anti-cyclonic eddies in the winter of 2003/2004 in the northern SCS, and three anti-cyclonic eddies in the summer of 2007 along 18°N were studied. The results show that the two anti-cyclonic eddies can propagate southwestward along the continental shelf at the speed of first Rossby wave (~0.1 ms-1 ) in winter, and the interaction between the three anti-cyclonic eddies in summer and the WBC in the SCS is preliminarily revealed. Eddies on the continental shelf of northern SCS propagated southeastward with a maximum speed of 0.09 ms-1 , and those to the east of Vietnam coast had the largest kinetic energy, both of which imply strong interaction between eddy activity and WBC in the SCS. Thirdly, strong intraseasonal variability (ISV) of sea surface temperature (SST) near the WBC regions was found, and the ISV signal of SST in winter weakens the ISV signal of latent heat flux by 20%. Fourthly, the long-term change of SCSTF volume transport and its connection with the ocean circulation in the Pacific were discussed. | WANG DongXiao LIU QinYan XIE Qiang HE ZhiGang ZHUANG Wei SHU YeQiang XIAO XianJun HONG Bo WU XiangYu SUI DanDan | 2013 | Chinese Science Bulletin2013，58，11： | 10 |
| 4 | 南海上层环流对不同气候态风场响应的数值研究显示文摘文章利用4种不同的气候态风场Scatterometer Climatology of Ocean Winds(SCOW)、Climate Forecast System Reanalysis(CFSR)、the Interim ECMWF Re-Analysis(ERA-Interim)和NECP[the National Centers for Environmental Prediction(NCEP)/National Center for Atmospheric Research(NCAR)Reanalysis 1]分别驱动区域海洋环流模式(Regional Ocean Modeling System,ROMS)以模拟南海环流,从而比较分析南海上层环流模拟结果的差异及其与风应力场之间的动力联系。结果表明,4种风场均能模拟出南海海盆尺度环流的季节变化特征,但对南海局地环流特征的模拟存在差异。分析显示,局地显著的正风应力旋度是冬季吕宋冷涡产生的根本原因;夏季越南东部海域的上层环流偶极子在模拟试验结果中均显现,但其强度与局地风应力旋度大小有关。海峡通量的模拟结果显示,吕宋海峡水体通量受海峡风场差异影响较小;台湾海峡秋冬季水体通量则有较大差别,强东北季风不利于海峡北向水体输送。此外,台湾海峡冬季较强的北向水体输送有利于南海暖流的生成。研究结果对深入理解南海上层环流对大气强迫的响应有裨益,并且可为不同目的的南海环流数值模拟时的风场选择提供参考。 | 闫桐 齐义泉 经志友 | 2015 | 热带海洋学报2015，34，4： | 4 |
| 5 | 2012年10月和12月南海北部海流的观测研究显示文摘基于2012年10月和12月两次南海北部走航ADCP和站位CTD等资料,分析了南海北部海流的流速结构和温盐特征。通过校正ADCP失准角,将ADCP流速测量精度控制在5 cm/s,并得到两个航次7个断面的流速数据。走航ADCP成功地观测到了南海西边界流和南海暖流,其中西边界流流幅和厚度分别为120 km和200 m,顺风流向西南,最大流速和流量范围分别为30~67 cm/s和0.74~9.70 Sv(1 Sv=106m3/s);而暖流流幅和厚度分别为40 km和600 m,呈带状结构,逆风流向东北,最大流速和流量范围分别为12~18 cm/s和0.14~1.13 Sv。对海南岛东部同一断面不同时间的两次观测表明,海流的流速结构发生了一定的变化,10月观测时西边界流和暖流分别位于陆架附近的表层和陆坡附近200 m以深的次表层,而12月观测时暖流出现在陆架附近表层到800 m以深的全深度范围,西边界流则分布于暖流南北两侧。在海南岛南部17.1°N、109.9°E附近观测到有暖流通过,此暖流的位置是迄今为止所有报道中的最西侧。 | 马云龙 朱小华 张钟哲 龙钰 樊孝鹏 | 2014 | 大连海洋大学学报2014，29，3： | 4 |
| 6 | The winter western boundary current of the South China Sea:physical structure and volume transport in December 1998显示文摘The unique survey in December 1998 mapped the entire western boundary area of the South China Sea(SCS),which reveals the three-dimensional structure and huge volume transport of the swift and narrow winter western boundary current of the SCS(SCSwwbc) in full scale. The current is found to flow all the way from the shelf edge off Hong Kong to the Sunda Shelf with a width around 100 km and a vertical scale of about 400 m. It appears to be the strongest off the Indo-China Peninsula, where its volume transport reached over 20×10~6 m^3/s. The current is weaker upstream in the northern SCS to the west of Hong Kong. A Kuroshio loop or detached eddy intruded through the Luzon Strait is observed farther east where the SCSwwbc no more exists. The results suggest that during the survey the SCSwwbc was fed primarily by the interior recirculation of the SCS rather than by the'branching' of the Kuroshio from the Luzon Strait as indicated by surface drifters, which is likely a near-surface phenomenon and only contributes a minor part to the total transport of the SCSwwbc. Several topics related to the SCSwwbc are also discussed. | LI Li GUO Xiaogang WU Risheng | 2018 | Acta Oceanologica Sinica2018，37，3： | 4 |
| 7 | 南海东北部陆缘浊流活动的地貌记录及其形成机制分析显示文摘超临界浊流影响下的周期阶坎广泛分布在南海东北部台西南盆地的西澎湖峡谷中。由于频繁的构造活动,常年的台风影响,以及来自中国台湾河流的大量沉积物供给,导致这个区域的浊流活动经常发生。本文利用高分辨率的地貌资料,对西澎湖峡谷发育的23个净侵蚀周期阶坎和10个净沉积周期阶坎进行了形态的定量分析,并且统计了流经这些周期阶坎的浊流流速。结果显示,浊流在流经净侵蚀周期阶坎过程中的速度有明显突变,而在净侵蚀到净沉积周期阶坎的过程中速度也发生了明显的降低,前者由峡谷中的坡折带导致,后者则是由限制性环境到非限制性环境的转变造成的。此外,净沉积周期阶坎主要分布于靠近峡谷口外的西南侧,这是由于科氏力对浊流影响的结果。研究此区域周期阶坎的形态特征和形成机制能够帮助我们更好地理解海底地形地貌与浊流的相互关系,对于理解峡谷中的地貌演化具有重要意义。 | 李爽 李伟 詹文欢 | 2021 | 热带海洋学报2021，40，1： | 2 |
| 8 | 南海西边界强流区季节和年际变化特征显示文摘基于1951—2010年SODA海洋同化数据资料,研究分析了南海西边界强流的季节及年际变化的特征,目的是为进一步探讨南海西边界强流的季节及年际变化机理奠定基础。分析研究发现:(1)南海西边界强流空间位置、水平和垂向范围及环流形态等季节变化明显,冬季环流形态空间位置稳定,强流一般9、10月份出现并开始加强,最强出现在12月份,1月份开始逐渐减弱。强流的水平范围一般为60—110 km,垂向范围在50—200 m之间,水平和垂向范围一般随着强流的增强(减小)而扩大(缩小);夏季环流形态变化较为复杂,强流空间位置不稳定,且逐步分裂成两支,一支移至近岸,一支在离岸原中心附近,分裂过程呈现由北向南推进的趋势,近岸支强度、垂向范围季节上没有明显变化规律,但北、中和南部有差别,北部分裂不明显且流速不大,南部分裂明显且近岸支流速较大;(2)南海西边界强流存在显著的年际变化,在转换月份上,夏季形态转换月份最早为2月份,最迟则到6月份,冬季形态转换月份最早为8月份,最迟则到11月份;流量输送上,冬季最大年份的达到23.3Sv,最小的年份流量只有1.5Sv,年际最大差异20Sv以上,夏季年际最大差异幅度也有10Sv以上;利用小波能谱分析南海西边界强流在年际变化上具有两个显著的准周期振荡:36个月(3 a)和大约99个月(8—9 a);(3)在1950年至2010年61 a时间段里,南海西边界流流量体积输送总体呈现出一种缓慢增加的趋势。 | 张成成 蒋国荣 陈奕德 刘子龙 | 2016 | 海洋预报2016，33，6： | 2 |
| 9 | 南海中尺度涡上海面热通量异常的季节变化显示文摘利用1999—2009年基于卫星观测反演的湍流热通量数据,并结合最新的涡旋数据集,通过合成分析的方法研究了南海涡旋导致的湍流热通量异常的季节差异及形成机理。结果表明,涡旋引起的热通量异常的水平分布表现出明显的季节差异,与涡旋导致的海表温度(SST)异常的分布特征相一致:在冬季表现为非中心对称(类似于偶极子)分布特征,而夏季则为中心对称(类似于单极子)分布特征。在涡旋内部旋转流场的作用下,因南海在不同季节其背景SST的分布不同,使得涡旋导致的热平流异常也显著不同,进而使得伴随涡旋的SST异常分布表现为单极型和偶极型。在SST异常的作用下,海面热通量异常分布也表现出相似的分布特征和季节差异。进一步分析发现,涡旋引起的热通量异常与SST异常呈线性关系,且两者的线性拟合斜率也表现出显著的季节变化:冬季的拟合斜率大于夏季。通过分析背景场的季节特征发现,背景风速和海气温差的季节差异是造成拟合斜率季节变化的主要原因。 | 祖永灿 孙双文 赵玮 李培良 刘宝超 方越 | 2019 | 海洋科学进展2019，37，1： | 2 |
| 10 | Formation of an anticyclonic eddy and the mechanism involved: a case study using cruise data from the northern South China Sea显示文摘Data from satellite altimetry and in situ observations together with the Hybrid Coordinate Ocean Model (HYCOM) reanalysis data were used to investigate the mechanism and formation of an anticyclonic eddy in the northeastern South China Sea (SCS). Analysis of water mass using cruise data indicated that the water captured in the eddy diff ers from those in the SCS, the Kuroshio intrusion, and the eddy-forming region. Data from sea surface height (SSH) and sea level anomaly (SLA) indicate that the eddy formed due both to the Kuroshio intrusion and the local circulation in the SCS. The Kuroshio intrusion is present at the start of the eddy growth (March 5-9) before Kuroshio leaps the Luzon Strait. The eddy then becomes larger and stronger in the absence of the Kuroshio intrusion. From the eddy budget of the HYCOM reanalysis data, the formation of the eddy goes in three steps. By the third step, the eddy had become aff ected by variations of local SCS circulation, which is more strongly than in the fi rst step in which it is aff ected more by the Kuroshio intrusion. The variability of the temperature and salinity inside the eddy provide a support to this conclusion. The water in the SCS intruded into the eddy from the southeast, which decrease the salinity gradually in the southern part of the eddy during the growth period. | HOU Huaqian XIE Qiang XUE Huijie SHU Yeqiang NAN Feng YIN Yuqi YU Fei | 2019 | Journal of Oceanology and Limnology2019，37，5： | 1 |
| 11 | 中南半岛近海偶极子演变过程研究显示文摘中南半岛近海偶极子结构是指在夏季与越南离岸流伴生的一对中尺度涡现象,其中气旋涡位于离岸流北侧,反气旋涡位于离岸流南侧,偶极子结构对于中南半岛近海水文要素具有重要影响。本文基于卫星高度计数据和HYCOM海洋模式的模拟结果,以2012年为例研究了该偶极子的演变过程,结果表明:偶极子结构7月出现,9月初鼎盛,10月消失;鼎盛时,两个涡旋直径均大于300km,在温跃层引起的最大位温异常可达±5℃。垂向结构上,反气旋涡呈中心对称,而气旋涡有非对称性,且影响深度大于反气旋涡。在200m以下,气旋涡有随深度增加向东倾斜的趋势,而反气旋涡有随深度增加向西偏移的趋势,但该趋势在200m层以上并不显著。对偶极子涡旋区域进行能量分析,结果表明偶极子能量主要来自于越南离岸流提供的正压和斜压能量,即越南离岸流区域是偶极子结构的主要能量源,局地风场对偶极子结构的维持也具有重要作用。能量既可以由离岸流输送给涡旋,也可以从涡旋向离岸流转化,但总体上是离岸流向涡旋提供能量。 | 裘是 陈学恩 唐声全 | 2020 | 海洋与湖沼2020，51，6： | 1 |
| 12 | 中国海和泰国湾海域海平面的经向涛动显示文摘卫星高度计遥感海面高度距平资料(1992-2012年)的分析结果证实中国海(渤、黄、东海及南海)和泰国湾作为一个半封闭的狭长水域,其海平面存在显著的南北经向涛动。涛动呈现明显的季节性,冬季南高北低,夏季北高南低,以渤海和泰国湾的海平面高差作为涛动的测度,其多年平均波动幅度达63cm,较差超过80cm。时间序列分析显示,在季节尺度上这一涛动几乎完全受东亚季风的支配,表明东亚季风的局地强迫是造成季节涛动的主要原因。进一步的分析发现,除季节波动之外研究海域海平面的经向涛动还存在明显的年际变化。不过,与季节尺度的波动有所不同,经向涛动的年际变化不仅是东亚季风区局地作用的结果,而且与太平洋海盆尺度的大气强迫有关,其作用与季风在同一数量级。涛动的年际变化大致滞后各气候因子两个月。采用多输入线性模型做偏相关分析筛选的结果显示,除东亚季风指数之外,研究海域的海平面涛动指数主要与太平洋的南方涛动指数(SOI)和西太平洋遥相关指数(WP)相关。这表明外部强迫既来自热带,也来自中纬度。南方涛动所导致的赤道海域海平面的东西向年际涛动,以及中纬度西风急流年际波动对西北太平洋海平面的作用,都有可能导致研究海域海平面经向涛动的年际变化,其机制有待进一步探讨。 | 李立 | 2014 | 海洋学报2014，36，9： | 1 |
| 13 | 夏季南海北部粤东陆架锋面的动力特征分析显示文摘本文利用现场观测资料和卫星遥感数据,并结合ROMS(regional ocean modeling system)数值模拟对南海北部粤东陆架的锋面特征及其影响因素进行探讨。观测结果显示,夏季南海北部陆架存在活跃的上升流温度锋面,其水平尺度约为50km,强度达到0.06℃·km^(–1),大于同时期卫星遥感观测结果,垂向影响深度超过20m,且具有一阶理查森数(Richardson number,Ri)的典型动力学特征。进一步的ROMS模式诊断分析结果显示,锋面处水平梯度增强,且动力学上表现出一阶Ri数,为锋面不稳定的发生提供了有利条件。高分辨率模拟结果显示,在夏季西南风的驱动下,沿锋面地转流方向的风应力引起的跨陆架Ekman输运将锋面处冷水向暖水运移,导致水平浮力梯度和锋面强度增强并形成负Ertel位涡(Ertel potential vorticity,EPV)。因此,夏季风场强迫引起的Ekman浮力通量(Ekman buoyancy flux,EBF)可能是南海北部锋面不稳定现象的主要贡献者,对局地动力环境有重要影响。 | 曾毅港 经志友 黄小龙 郑瑞玺 | 2022 | 热带海洋学报2022，41，4： | 1 |
| 14 | 南海一个罗斯贝标准模态的特征与归因显示文摘南海是一个准封闭海盆,其本征值问题是理解南海动力学的重要内容。本文利用一种新的泛函工具—多尺度子空间变换,从卫星观测资料中分离得到一个南海本征模态,即罗斯贝标准模态的近似场。发现该模态的周期为6个月左右、波长近250km,在深水海盆向西传播,这与寿命为3个月左右的南海中尺度涡群体活动特征相一致。在此基础上,本文通过Liang-Kleeman信息流这一严格建立在第一性原理上的定量因果分析工具,探究南海两个最重要外部强迫,即黑潮入侵与南海季风对该罗斯贝标准模态的影响。结果表明二者与该模态均有较强因果关系,但分别影响模态的不同阶段:黑潮入侵主要影响其1/2π和3/2π位相,季风的作用则体现在3/4π位相。二者共同作用,调制该模态在近一个周期内的变化。进一步研究发现,黑潮入侵的过渡态是影响该模态的关键,这时黑潮在南海的分支与流套强度相当,有利于吕宋海峡西部形成不同极性涡旋的排列,从而影响南海内部罗斯贝标准模态。对南海季风而言,冬季风与夏季风的成熟阶段是影响该模态的重要时期,但并非整个南海的季风都发挥作用,泰国湾是季风改变南海罗斯贝标准模态的关键区域,这表明局地的强迫对激发全局模态起作用。 | 赵宇慧 马继望 梁湘三 | 2023 | 海洋学报2023，45，10： | 0 |
| 15 | Reversal process of the South China Sea western boundary current in autumn 2011显示文摘Using merged sea level anomaly and absolute geostrophic velocity products from satellite altimetry and Argos drifter data,we analyzed the reversal process of the South China Sea(SCS) western boundary current(SCSwbc) from a summer to winter pattern in 2011 and important oceanic phenomena during this process.Results show that the outbreak time of the northeast monsoon over the southern SCS lagged that over the northern SCS by about 1 month.During the SCS monsoon reversal period,the SCSwbc reversed rapidly into the winter pattern at the Guangdong continental slope in late September.Subsequently,the southward Vietnam coastal boundary current strengthened.However,the northward Natuna Current maintained a summer state until mid-October.Thus,the balance between the southward and northward currents was lost when they met,their junction moved gradually southward.However,a loop current formed southeast of Vietnam because the main stream of the Vietnam Offshore Current(VOC) remained near its original latitude.Meanwhile,the VOC and associated dipole circulation system strengthened.After midOctober,the northward Natuna Current began to weaken,the loop current finally shed,becoming a cool ring.The VOC and its associated dipole sub-basin circulation system also weakened gradually until it disappeared. | 张志欣 郭景松 郭炳火 | 2016 | Chinese Journal of Oceanology and Limnology2016，34，3： | 0 |
| 16 | 南海贯穿流荷载中尺度过程能量学诊断显示文摘本文利用南海海洋再分析产品REDOS(Reanalysis Dataset of the South China Sea)和风场资料CCMP(Cross-Calibrated,Multi-Platform),通过能量诊断探讨了越南沿岸南海西边界流(南海贯穿流主体部分)区域夏季(6—9月)涡流相互作用的年际变化特征以及平均流对中尺度过程的贡献。结果显示,在季风和西边界强流、南海贯穿流的共同影响下,越南沿岸东向急流和双涡结构的能量分布和收支有显著的年际差异。尽管涡动能(EKE,Eddy Kinetic Energy)和涡动有效势能(EPE,Eddy available Potential Energy)的量级基本一致,但二者在水平和垂向空间分布上存在明显差异,这与夏季风影响下的南海西部边界流,越南离岸流的上层海洋密度梯度、流速大小和剪切导致的斜压、正压不稳定性等因素相关。同时随着深度的增加,密度梯度变化相对水平速度剪切对海洋涡流过程的影响逐渐凸显。EKE能量收支分析表明,压强与风应力主要做正功,是维持EKE稳定的主要能量来源,而EKE平流项既可以促进涡旋的增长,也会造成涡旋的消耗,对EKE的年际变率影响比较显著。正压不稳定导致的能量转换主要影响南海西部边界流区域,并存在显著年际变化,并且在风和平均流的影响下,沿贯穿流方向存在显著空间分布差异。越南离岸流正异常年,整体呈现平均流向涡旋传递能量;负异常年,出现EKE反哺平均动能的情况。 | 姚景龙 李晗 刘钦燕 王强 肖福安 王东晓 俎婷婷 | 2017 | 海洋与湖沼2017，48，6： | 0 |
| 17 | 一个小型热带河口羽流的季节性变化与洪水事件影响下的特征与动力分析显示文摘小河口与大河口的羽流特征具有显著的不同,其更多地受风、径流的变化所控制。文章以海南博鳌万泉河口为例,研究其河口羽流的季节性变化特征,以及洪水对河口羽流的影响。采用动量平衡方法,分析了万泉河口羽流的动力特征。结果表明,万泉河口羽流具有显著的季节性变化,羽流的扩展路径与范围主要受径流和风的控制,夏季时以向外海与向上游方向(相对于开尔文波的传播方向)扩展为主,而冬季时则向下游扩展。夏季的羽流范围大于冬季。一次近2天的洪水可极大地影响羽流的范围及盐度大小,盐度减小1‰的范围可达300km2。但洪水过后,在风与潮汐的混合作用下,河口近岸的盐度可较为快速地恢复到洪水前水平。在羽流的远场区域,流速切线方向主要为压强梯度力与摩擦力的平衡,而在法线方向则为地转平衡;在近场切线方向主要为平流项、压力梯度项与摩擦力项的平衡,而法线方向则主要为压强梯度力与离心力之间的平衡,科氏力项可忽略不计,这与中纬度大河口的近场动力特征具有明显不同。 | 赵军鹏 李溢涵 龚文平 | 2017 | 热带海洋学报2017，36，4： | 0 |
| 18 | Interannual to decadal variation of spring sea level anomaly in the western South China Sea显示文摘Satellite observations of sea level anomalies(SLA) from January 1993 to December 2012 are used to investigate the interannual to decadal changes of the boreal spring high SLA in the western South China Sea(SCS) using the Empirical Orthogonal Function(EOF) method. We find that the SLA variability has two dominant modes. The Sea Level Changing Mode(SLCM) occurs mainly during La Ni?a years, with high SLA extension from west of Luzon to the eastern coast of Vietnam along the central basin of the SCS, and is likely induced by the increment of the ocean heat content. The Anticyclonic Eddy Mode(AEM) occurs mainly during El Ni?o years and appears to be triggered by the negative wind curl anomalies within the central SCS. In addition, the spring high SLA in the western SCS experienced a quasi-decadal change during 1993–2012; in other words, the AEM predominated during 1993–1998 and 2002–2005, while the La Ni?a-related SLCM prevailed during 1999–2001 and 2006–2012. Moreover, we suggest that the accelerated sea level rise in the SCS during 2005–2012 makes the SLCM the leading mode over the past two decades. | 丘福文 方文东 潘爱军 查晶 张善武 黄奖 | 2017 | Chinese Journal of Oceanology and Limnology2017，35，1： | 0 |
| 19 | Response of Phytoplankton Community Structure and Size- Fractionated Chlorophyll a in an Upwelling Simulation Experiment in the Western South China Sea显示文摘The South China Sea(SCS), which is the largest marginal sea in the western tropical Pacific, plays an important role in regional climate change. However, the research on the phytoplankton community structure(PCS) response to the upwelling remains inadequate. In January 2014, the upwelling simulation experiment was performed in the western SCS. Results indicate that the nutrient-rich bottom water not only increased the total Chlorophyll a(Chl a) concentrations, but would potentially altered the PCS. Due to new nutrients added, microphytoplankton had more sensitivity response to nutrient uptake than other phytoplankton groups. The variation of nutrients induced by formation, weakening and disappearance of upwelling resulted in phytoplankton species succession from cyanophyta to bacillariophyta. It may be the leading factor of the changes in PCS and size-fractionated Chl a. The initial concentration of DIP less than 0.1 μmol L-1 could not sustain the phytoplankton growth. This indicates that phosphorus may be the limiting factor in the western SCS. | CUI Dongyang WANG Jiangtao TAN Liju | 2016 | Journal of Ocean University of China2016，15，5： | 0 |
| 20 | A comparison of the CMIP5 models on the historical simulation of the upper ocean heat content in the South China Sea显示文摘Seventeen models participating in the Coupled Model Intercomparison Project phase 5(CMIP5) activity are compared on their historical simulation of the South China Sea(SCS) ocean heat content(OHC) in the upper 300 m. Ishii's temperature data, based on the World Ocean Database 2005(WOD05) and World Ocean Atlas 2005(WOA05), is used to assess the model performance by comparing the spatial patterns of seasonal OHC anomaly(OHCa) climatology, OHC climatology, monthly OHCa climatology, and interannual variability of OHCa. The spatial patterns in Ishii's data set show that the seasonal SCS OHCa climatology, both in winter and summer, is strongly affected by the wind stress and the current circulations in the SCS and its neighboring areas. However, the CMIP5 models present rather different spatial patterns and only a few models properly capture the dominant features in Ishii's pattern. Among them, GFDL-ESM2 G is of the best performance. The SCS OHC climatology in the upper 300 m varies greatly in different models. Most of them are much greater than those calculated from Ishii's data. However, the monthly OHCa climatology in each of the 17 CMIP5 models yields similar variation and magnitude as that in Ishii's. As for the interannual variability, the standard deviations of the OHCa time series in most of the models are somewhat larger than those in Ishii's. The correlation between the interannual time series of Ishii's OHCa and that from each of the 17 models is not satisfactory. Among them, BCC-CSM1.1 has the highest correlation to Ishii's, with a coefficient of about 0.6. | WANG Gang LIN Min | 2014 | Acta Oceanologica Sinica2014，33，11： | 0 |
