12008与2010年黄海浒苔漂移输运特征对比显示文摘利用中国近海三维海浪-潮流-环流耦合数值模式,分别对2008年6~7月(青岛奥帆赛前期)和2010年6~7月黄海浒苔的漂移开展了模拟和预测,研究了黄海漂浮浒苔在青岛聚集的动力学成因.揭示了2008年6月浒苔之所以在青岛近岸大量聚集,是因为该海区月平均表层流向向岸且与岸线几乎垂直;相比之下,2008年7月上旬表层流场与岸线大致平行,因而海上浒苔的漂移对奥帆赛场的压力明显减缓.利用数值模式预测2010年6月下旬浒苔主体不会在青岛登陆,该预测与其后的观测事实相吻合.研究发现,风场驱动下的海洋表层流场年际变化是浒苔漂移路径变异的主要原因,提出区域气候变化是影响海洋生态系统的一种途径.乔方利 王关锁 吕新刚 戴德君 2011科学通报2011,56,18:40
22011年3月日本福岛核泄漏物质输运扩散路径的情景模拟和预测显示文摘2011年3月受日本以东地震和海啸影响,日本福岛核电站发生核物质泄漏.本文提出泄漏物质自然输运的3种通道:大气快速输运通道、海洋表层慢速输运通道和海洋内部极慢速输运通道.基于短期气候预测模式和海洋环流数值模式,在理想假设条件下,对核泄漏物质的输运扩散路径进行了情景模拟和预测.结果显示:若泄漏源设置在近地层992hPa,10d后影响范围可达北美大部地区,但浓度比所设置的源区浓度低约6个量级,15d后可影响到欧洲,20d后前锋进入中国西部地区,30d后则布满整个纬带;若泄漏源在5km高度,泄漏10d后影响范围可覆盖欧洲,15d即可布满整个纬带;若泄漏源在10km高度,10d后即可影响中国大部分区域.核泄漏物质通过海洋表层通道向东输运则缓慢得多,50d后到达150°E左右,且影响范围仅在一条狭窄条带内.大气通道影响范围巨大,甚至可到达赤道海域上空,但核泄漏物质的浓度很快降低.大气环流上游如北美和欧洲的大气质量监测结果对中国具有重要的参考价值.乔方利 王关锁 赵伟 赵杰臣 戴德君 宋亚娟 宋振亚 2011科学通报2011,56,12:28
3Drift characteristics of green macroalgae in the Yellow Sea in 2008 and 2010显示文摘In order to investigate the aggregation mechanism of green macroalgae (Enteromorpha prolifera) on the Qingdao coastline,the macroalgal drift characteristics in the Yellow Sea during June and July in 2008 and 2010 were simulated using a three-dimensional wave-tide-circulation coupled model.In June 2008,the monthly-mean surface current flowed onshore and its direction was almost perpendicular to the Qingdao coastline,which was identified as the main reason for a huge accumulation of algae in the coastal waters off Qingdao.The current became parallel to the coastline in July 2008;this shift in current direction led to little accumulation of algae near Qingdao and thus relieved the environmental pressure on the Olympic sailing events.By using the coupled model,we predicted that there would be no serious algal accumulation at Qingdao in late June 2010,which was later confirmed by observations.This study demonstrated that the drift path of macroalgae near Qingdao is mainly controlled by the surface current,which is primarily driven by wind.Regional climate change is therefore one of the means by which physical processes affect marine ecosystems.QIAO FangLi WANG GuanSuo LüXinGang DAI DeJun 2011Chinese Science Bulletin2011,56,21:25
4近岸强海流切变锋作用下悬浮沉积物的输送和沉积——以山东半岛东端外海为例显示文摘利用2007年国家908专项ST02区块(渤海海峡及北黄海)水体专项夏季和冬季两个航次调查的温度、浊度和悬浮体浓度数据,选取了跨越山东半岛东端外海泥质沉积体的B1和B2两个断面,结合该区浅地层剖面资料,辅以研究海域的冬季环流数值模拟,着重分析了山东半岛东端外海强海流切变锋作用下的悬浮体输送和沉积特征。结果表明山东半岛东端外海悬浮体向外海输送存在类似'夏储冬输'的规律:夏季,北黄海海水浊度普遍小,不仅北黄海温跃层抑制了底层悬浮体向中上层水体扩散,而且北黄海冷水团在中底层与山东半岛东部沿岸水也形成了显著的温度和悬浮体锋面,阻碍了悬浮物的纬向输送,故夏季应是悬浮体沉积的主要时节;冬季,温跃层消亡,在强风的作用下,山东半岛东部悬浮体浓度高且垂向混合较好,然而在泥质沉积体顶积层两侧,山东半岛东部沿岸中下层北上的逆风补偿流和北上的黄海暖流与位于顶积层上方表中层南下的沿岸流构成了两道显著的强海流切变锋,使得底积层上大量的再悬浮沉积物不能越过山东半岛东部陆架末梢,从而有助于形成山东半岛东端外海特有的Ω状泥质沉积体。王勇智 乔璐璐 杨作升 鲍献文 赵美训 王关锁 2013沉积学报2013,31,3:19
5Predicting the spread of nuclear radiation from the damaged Fukushima Nuclear Power Plant显示文摘Japan suffered a M9.0 earthquake and massive tsunami on March 11, 2011, which seriously damaged the Fukushima Nuclear Power Plant and caused a nuclear crisis. The spread of nuclear radiation from the power plant through the atmosphere and ocean was predicted with a short-term climate forecasting model and an ocean circulation model under some idealized assumptions. If nuclear matter were leaked in the near-ground layer of 992 hPa, the climate model results show that the nuclear radiation would cover North America 10 days after the initial leakage, with the concentration at the forefront dramatically reduced to 10 millionths of the initial model concentration at the source. The radiation would span Europe in 15 days and cover much of the Northern Hemisphere in 30 days. If the initial leakage was assumed to occur in the layer 5000-m above the ground, the radiation would cover Europe in 10 days and cover much of the Northern Hemisphere in 15 days. Moreover, under the assumption that the nuclear matter leaked in the 10000-m layer, the radiation would affect much of China after 10 days. The ocean circulation model indicates that the nuclear material would be slowly transported northeast of Fukushima and reach 150°E in 50 days, and the nuclear debris in the ocean would be confined to a narrow band. Compared with the spread in the ocean, the area affected by leaked nuclear radiation in the atmosphere would be very large. Atmospheric monitors in North America and Europe will be helpful for estimating the effect in China of any leaked nuclear material.QIAO FangLi WANG GuanSuo ZHAO Wei ZHAO JieChen DAI DeJun SONG YaJuan SONG ZhenYa 2011Chinese Science Bulletin2011,56,18:18
6The role of surface waves in the ocean mixed layer显示文摘Previously,most ocean circulation models have overlooked the role of the surface waves.As a result,these models have produced insufficient vertical mixing,with an under-prediction of the mixing layer(ML)depth and an over-prediction of the sea surface temperature(SST),particularly during the summer season.As the ocean surface layer determines the lower boundary conditions of the atmosphere,this deficiency has severely limited the performance of the coupled ocean-atmospheric models and hence the climate studies.To overcome this shortcoming,a new parameterization for the wave effects in the ML model that will correct this systematic error of insufficient mixing.The new scheme has enabled the mixing layer to deepen,the surface excessive heating to be corrected,and an excellent agreement with observed global climatologic data.The study indicates that the surface waves are essential for ML formation,and that they are the primer drivers of the upper ocean dynamics;therefore,they are critical for climate studies.QIAO Fangli YANG Yongzeng XIA Changshui YUAN Yeli 2008Acta Oceanologica Sinica2008,27,3:13
7An improvement of the too cold tongue in the tropical Pacific with the development of an ocean-wave-atmosphere coupled numerical model显示文摘在没有流动修正的联合海洋空气将军发行量模型(CGCM ) 的申请的一个普通问题是模仿的赤道的冷舌头一般来说趋于太强壮,狭窄,并且向西延长太远。原因还很好没被理解。一个可能的原因可以是模仿的混合的层深度(MLD ) 由于在 OGCM 的不够的垂直混合在热带太平洋是太浅的。导致波浪的垂直混合罐头极大地改进 MLD 和 thermocline 结构的模拟,这被相信。在这研究,与导致波浪的混合合并的联合海洋空气将军发行量模特儿(FGCM-0 ) 被雇用了模仿热带和平的海表面温度(SST ) 。通常,因为,导致波浪的混合在 OGCM 降低 SST 加强的垂直混合能向上带更多的冷水。在联合模型,然而,在 SST 落下的空间分发的不一致产生海表面空气压力的一个水平坡度,并且因此产出表面风领域异例。风异例导致两个海洋表面发行量异例,并且在能制止的 welling 异例下面过分向西在热带太平洋的冷舌头的扩展。与从原来的模型(FGCM-0 ) 的模型结果相比,建模的 SST 由超过 0.8 ° C 是更高的,与在西方的太平洋的 1.2 ° C 的最大值(160-180 ° E, 0-3 ° N ) 。26.0 ° C 的等温线的东方边界也从 165 ° E 搬到 180 ° E。过分,向西,模仿的赤道的冷舌头的扩展与在联合模型的导致波浪的混合的加入被压制。模仿的 SST 表演一般来说与超过 1 的最大的改进改进了结果。0 ° C。在向北热带的太平洋的模仿的 SST 改进比向南热带的太平洋的好一些。Song Zhenya Qiao Fangli Yang Yongzeng Yuan Yeli 2007Progress in Natural Science:Materials International2007,17,5:13

11The correctness to the spuriously simulated semi-annual cycle of the sea surface temperature in the equatorial eastern Pacific显示文摘One of the challenges faced by the climate model of the Community Climate System Model version 3 (CCSM3) is the spuriously simulated semi-annual cycle of the sea surface temperature (SST) in the equatorial eastern Pacific. This model bias has limited the performance of the climate simulation and prediction. Based on the surface wave-circulation coupled theory, an atmosphere-wave-ocean coupled model was developed, which incorporates the MASNUM (key laboratory of Marine Sciences and Numerical Modeling) wave number spectral model into CCSM3. The new coupled atmosphere-wave-ocean model successfully removes the spurious semi-annual cycle simulated by the original CCSM3 and reasonably produces an SST annual cycle with warm and cold phases in April and August, respectively. The correlation between the simulated and observed SST in the equatorial eastern Pacific is improved from 0.66 to 0.93. The ocean surface layer heat budget analysis indicates that the wave-induced vertical mixing is responsible for improving the simulation of the SST seasonal cycle in the equatorial eastern Pacific.SONG ZhenYa QIAO FangLi WANG ChunZai 2011Science China Earth Sciences2011,54,3:10
12黄海浒苔漂移输运模式的建立与应用显示文摘本文利用NCEPGFS预报风场和中国近海高分辨率三维MASNUM海浪-潮流-环流耦合海洋数值预报系统的预报数据,建立黄海浒苔漂移输运模式,用于黄海浒苔溯源和漂移输运数值模拟研究。使用2009年5月份黄海表层漂流浮标数据和2012年MODIS卫星遥感浒苔漂移分布资料对所建立的漂移输运模式进行验证,结果表明所建立的模式能够有效的模拟出浒苔暴发区漂流浮标运动状况,并能够有效地模拟出2012年浒苔漂移输运过程。最后运用所建立的模式开展2008年和2010年浒苔漂移输运过程,模拟结果与文献报道的卫星观测结果一致。模拟结果表明,受海洋表层流影响两年浒苔特征显著不同:2010年浒苔影响海域明显小于2008年,且2010年浒苔主体没有大规模在青岛近岸堆积。赵昌 尹丽萍 王关锁 乔方利 王刚 夏长水 2018海洋与湖沼2018,49,5:8
13Evaluation on data assimilation of a global high resolution wave-tide-circulation coupled model using the tropical Pacific TAO buoy observations显示文摘In order to evaluate the assimilation results from a global high resolution ocean model, the buoy observations from tropical atmosphere ocean(TAO) during August 2014 to July 2015 are employed. The horizontal resolution of wave-tide-circulation coupled ocean model developed by The First Institute of Oceanography(FIOCOM model) is 0.1°×0.1°, and ensemble adjustment Kalman filter is used to assimilate the sea surface temperature(SST), sea level anomaly(SLA) and Argo temperature/salinity profiles. The simulation results with and without data assimilation are examined. First, the overall statistic errors of model results are analyzed. The scatter diagrams of model simulations versus observations and corresponding error probability density distribution show that the errors of all the observed variables, including the temperature, isotherm depth of 20°C(D20), salinity and two horizontal component of velocity are reduced to some extent with a maximum improvement of 54% after assimilation. Second, time-averaged variables are used to investigate the horizontal and vertical structures of the model results. Owing to the data assimilation, the biases of the time-averaged distribution are reduced more than70% for the temperature and D20 especially in the eastern Pacific. The obvious improvement of D20 which represents the upper mixed layer depth indicates that the structure of the temperature after the data assimilation becomes more close to the reality and the vertical structure of the upper ocean becomes more reasonable. At last,the physical processes of time series are compared with observations. The time evolution processes of all variables after the data assimilation are more consistent with the observations. The temperature bias and RMSE of D20 are reduced by 76% and 56% respectively with the data assimilation. More events during this period are also reproduced after the data assimilation. Under the condition of strong 2014/2016 El Ni?o, the Equatorial Undercurrent(EUC) from the TAO is gradually increased during August to November in 2014, and followed by a decreasing process. Since the improvement of the structure in the upper ocean, these events of the EUC can be clearly found in the assimilation results. In conclusion, the data assimilation in this global high resolution model has successfully reduced the model biases and improved the structures of the upper ocean, and the physical processes in reality can be well produced.SHI Junqiang YIN Xunqiang SHU Qi XIAO Bin QIAO Fangli 2018Acta Oceanologica Sinica2018,37,3:7
14静态集合样本的构造及其在全球海浪滤波同化中的应用显示文摘本文提出一种最佳静态集合样本的构造方法,利用不同时段内海浪有效波高的模拟偏差构造静态集合样本,并将其与由模拟结果和观测资料统计的模式误差进行概率密度分布及时空相关性分析,结果表明24h间隔有效波高偏差与后者的相关性最好,称为最佳静态集合样本,可用于近似背景误差。将所构造的静态集合样本应用于滤波同化调整过程,采用MASNUM海浪模式,利用Jason-1卫星高度计数据,对2008年全球海域开展海浪同化实验,实验结果表明,基于最佳静态集合样本的海浪同化调整,可以有效地改善海浪模式的模拟效果。孙盟 尹训强 杨永增 2014海洋与湖沼2014,45,5:6
15MASNUM海浪模式的性能特点分析与并行优化显示文摘海浪模式MASNUM(marine science and numerical modeling)是我国自主研发的海浪数值模式,该模式已广泛应用于我国海洋防灾减灾、海上交通运输、军事活动保障等方面的海浪预报中.随着提升业务预报精度和气候研究需求的不断增长,高分辨率成为海浪模式发展的必由之路.尽管高性能计算机的快速发展为高分辨率数值模式提供了强大的计算能力支持,但当前很多并行数值模式效率还不高,无法获得更高并行加速比,无法提高模式并行效率并缩短运行墙钟时间.结合现代高性能计算机体系结构特点,深入分析MASNUM模式的性能瓶颈,继而有针对性地对其开展并行优化,明显地提升了通信性能、I/O性能和二维剖分负载平衡性,进而提升了MASNUM模式整体并行效率和可扩展规模.这里以串行性能为基准,当扩展规模达到960个CPU核时,改进后版本加速比可达431.5.该研究也为其他数值模式提供了一些可供借鉴的并行优化策略.张志远 周宇峰 刘利 杨广文 2015计算机研究与发展2015,52,4:6
16山东半岛东部海域悬浮体分布季节变化及其冬季输送通量研究显示文摘山东半岛东部近岸海域流系和水团要素季节变化显著,沉积动力环境特殊,发育有剖面形状独特的泥质沉积体。基于两个年度的夏、冬季山东半岛东部近岸海域水体温度、浊度、悬浮体浓度和海流等调查资料,分析了水团要素分布季节变化特征,并结合研究区域冬季海流和余流分布特征,计算了冬季经山东半岛东部近岸海域向南输送的悬浮体净通量。结果表明:山东半岛东部近岸海域悬浮体分布受沿岸流、黄海冷水团和黄海暖流等流系季节变化的影响存在显著季节变化。夏季,水体垂向层结和黄海冷水团均可抑制悬浮体垂向和东西向扩散。与以往的研究有所不同的是,冬季大量悬浮体可穿越沿岸流与黄海暖流形成的海流切变锋面,进入黄海暖流向北输送,海流切变锋的屏障作用会随着黄海暖流的减弱或东移而削弱。每年冬季经山东半岛东部近岸海域输送的悬浮体占渤海海峡向外海输送的悬浮体年净通量的3.22%~9.10%,冬季的悬浮体输送量较大,占冬季渤海海峡向外海输送的悬浮体年净通量的6.84%~19.38%。王勇智 张永强 孙惠凤 2019沉积学报2019,37,3:6
17波致混合对热带太平洋海气耦合模式中冷舌模拟的改进显示文摘非通量调整的大气-海洋环流耦合数值模式所模拟的赤道太平洋表层海温(SST)的冷舌偏冷并且过于西伸是一个共性问题.文中在全球大气-海洋环流耦合数值模式FGCM-0中考虑了波致混合的作用后,赤道太平洋地区的SST模拟结果有了显著的改善,在(160—180°E,0—3°N)海域内SST升高在0.8℃以上且最大可达1.2℃.这有效地抑制了冷舌西伸,即赤道太平洋冷舌过于西伸的问题有所改善,26.0℃等温线在赤道附近的顶点从165°E东移至180°E以东,大约向东移动了1650km,这样所模拟的SST更接近于观测.对模拟结果分析表明:耦合模式中SST、近海面大气环流、海洋表层水平环流、海洋表层上升流等要素的距平场是相互间动力协调的,对于改善赤道冷舌模拟偏冷问题是正反馈,而耦合模式中海气热通量距平对改善赤道冷舌模拟偏冷问题是一种负反馈.宋振亚 乔方利 杨永增 袁业立 2006自然科学进展2006,16,9:6
18波致混合对CCSM3气候模式预测能力的改进显示文摘在海气耦合模式CCSM3基础上引入波致混合作用后建立了改进的海气耦合模式,设计了SST同化方案,并进行了2005,2006和2007年ENSO的集合后报和2008年气候预测数值试验.结果表明,改进的海气耦合模式的同化效果优于原来的海气耦合模式CCSM3的同化效果.集合后报与观测资料对比表明:改进的海气耦合模式能够较好地预测当年ENSO事件的发生情况,预报强度和成熟期特征与实际也较吻合,波致混合可以明显地提升气候模式的预测能力.在此基础上利用改进的海气耦合模式对2008年气候异常进行了集合预测,结果表明:始于2007年的LaNia事件将持续至2008年夏季,2008年ElNio事件出现概率很小;2008年夏季中国东南沿海、黄淮流域、东北东南部、新疆中南部以及青藏高原西部降水比往年偏多,局部可能出现洪涝,内蒙古西部、华南西南部以及青藏高原南部降水比往年偏少.我国沿海除两广地区和长江口附近地区外,均有不同程度的降水增加.宋振亚 乔方利 赵伟 2009自然科学进展2009,19,2:6
19Parameterization of ocean wave-induced mixing processes for finite water depth显示文摘Three dimensional wave-induced mixing plays an important role in shallow water area. A quite direct approach through the Reynolds average upon characteristic length scale is proposed to pa-rameterize the horizontal and vertical shallow water mixing. Comparison of finite depth case with infinite depth results indicates that the difference of the wave-induced mixing strength is evident. In the shallow water condition, the infinite water depth approximation overestimates the mixing strength in the lower layers. The nonzero horizontal wave-induced mixing presents anisotropic prop-erty near the shore. The Prandtl's mixing length theory underestimated the wave-induced mixing in the previous studies.YANG Yongzeng ZHAN Run TENG Yong 2009Acta Oceanologica Sinica2009,28,4:6
20Energy budget of surface waves in the global ocean显示文摘Mechanical energy input from atmosphere and losses from wave-breaking dissipation of sea surface waves are estimated by a direct scheme. This scheme is based on the integration in the wavenumber space of the wind input and breaking dissipation source functions of the MASNUM wave model. The global amount of wind energy input, averaged in 2005, is about 57 TW, and the wave-breaking dissipation summed in deep-water is about 33 TW, over a half of the wind energy input. The residual may be dissipated by beach processes. Global distributions of the energy input and breaking dissipation concentrate in the westerlies of the Southern Hemisphere.TENG Yong YANG Yongzeng QIAO Fangli LU Jing YIN Xunqiang 2009Acta Oceanologica Sinica2009,28,3:6
