El Nino-Southern Oscillation(ENSO) is the strongest interannual signal that is producedby basinscale processes in the tropical Pacific,with significant effects on weather and climate *** the past,extensive and intensive international efforts have been devoted to coupled model developments for ENSO studies.A hierarchy of coupled ocean-atmo sphere models has been formulated;in terms of their complexity,they can be categorized into intermediate coupled models(ICMs),hybrid coupled models(HCMs),and fully coupled general circulation models(CGCMs).ENSO modeling has made significant progress over the past decades,reaching a stage where coupled models can now be used to successfully predict ENSO events 6 months to one year in ***,ENSO exhibits great diversity and complexity as observed in nature,which still cannot be adequately captured by current state-of-the-art coupled models,presenting a challenge to ENSO *** primarily reviewed the long-term efforts in ENSO modeling continually and steadily made at different institutions in China;some selected representative examples are presented here to review the current status of ENSO model developments and applications,which have been actively pursued with noticeable progress being made *** ENSO simulations are very sensitive to model formulations and process representations etc.,dedicated efforts have been devoted to ENSO model developments and ***,different ocean-atmosphere coupled models have been available in China,which exhibit good model performances and have already had a variety of applications to climate modeling,including the Coupled Model Intercomparison Project Phase 6(CMIP6).Nevertheless,large biases and uncertainties still exist in ENSO simulations and predictions,and there are clear rooms for their improvements,which are still an active area of researches and ***,model performances of ENSO simulations are assessed in terms of advantages and disadvantage

A model of the formation and development of ocean shear wave

Acta Oceanologica Sinica 1994年第3期13卷 345-359页

作者： qiao fangli and Zhang Qinghua(First Institute of Oceanography,state oceanic Administration,P.O.Box 98,Qingdao 266003,China)

From quasi-geostrophic vorticity equation, we simulate the formation of ocean shear wave in western boundary strong current area with the pseudospectral method, and idealize the initial velocity into hyperbolictangent velocity profile, with the unsteady little perturbation developed by means of getting energy from meanmotion. The change of isovorticity shows two vortexes merging or splitting between them. The evolving processof material lines reflects cold water's invading and warm water's turning, which is agreeable to satellite *** effect makes a new energy distribution in all kinds of motion scale. One important phenomenon is that Reynolds stress will change its sign when the perturbation amplitude is large enough.

The Sunway Taihu Light supercomputer is the world’s first system with a peak performance greater than 100 PFlops. In this paper, we provide a detailed introduction to the Taihu Light system. In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators(NVIDIA GPU or Intel Xeon Phi), the computing power of Taihu Light is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements(MPEs)and computing processing elements(CPEs) in one chip. With 260 processing elements in one CPU, a single SW26010 provides a peak performance of over three TFlops. To alleviate the memory bandwidth bottleneck in most applications, each CPE comes with a scratch pad memory, which serves as a user-controlled cache. To support the parallelization of programs on the new many-core architecture, in addition to the basic C/C++and Fortran compilers, the system provides a customized Sunway Open ACC tool that supports the Open ACC2.0 syntax. This paper also reports our preliminary efforts on developing and optimizing applications on the Taihu Light system, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation.

Evidence of Upwelling along Peninsular Malaysia during Southwest Monsoon

Open Journal of Marine Science 2015年第3期5卷 273-279页

Upwelling off the east coast of Peninsular Malaysia (PM) was detected from recent cruise data collected during the southwest monsoon. Thermocline lifting was observed at 104?E from a number of parallel transects. To confirm the presence of upwelling, satellite remote sensing data were used, and numerical model experiments were conducted. A cooler sea-surface temperature along the coast was spotted from both in-situ and satellite data while upward movement from the model agreed with field data. The southwesterly wind that blows along PM from June to September is believed to be the important mechanism that contributed to this upwelling through an Ekman dynamics process.

Influences of the surface wave-induced mixing and tidal mixing on the vertical temperature structure of the Yellow and East China Seas in summer

引用

Progress in Natural Science:Materials International 2006年第7期16卷 739-746页

作者： qiao fangli, MA Jian, XIA Changshui, YANG Yongzeng and YUAN Yeli (Key Laboratory of Marine Science and Numerical Modeling, First Institute of Oceanography, State Oceanic Administration, Qingdao 266061, China) State Ocean Adm Inst Oceanog 1 Key Lab Marine Sci & Numer Modeling Qingdao 266061 Peoples R China

After a classification of the physical processes which affect the vertical mixing, diffusivity induced by the surface wave momentum and tidal currents and its influence on the vertical temperature structure are discussed. Based on three mixing schemes, the vertical temperature structure of the Yellow and East China Seas (YECS) is simulated. Results show that in summer, the surface wave-induced mixing plays a key role in forming the upper mixed layer in the YECS. The tidal mixing controls the lower layers within 30 m above the bottom, which is the main factor in forming the platform-shaped temperature structure in the southern Yellow Sea (YS). Together with the strong surface wave-induced mixing, the tidal mixing makes the thermocline ventilate near the east coast of the southern YS. The double cold cores in the deeper layers of the East China Sea have different causes. The western one is the maintenance of the winter cold water, while the eastern one is configured by circulation. The simulated vertical temperature structure of the YECS with the surface wave-induced mixing and tidal mixing has similar features to the observations, which indicates that these mixing processes are key factors in simulating the thermocline and pycnocline of the coastal oceans.

关键词： surface wave-induced mixing tidal mixing thermocline the Yellow Sea the East China Sea.

传染病的疫情传播过程符合广泛存在的自然增长率,其中疫情增长率根据疫情的发展而动态变化.近期提出的基于数据的疫情自然增长模型可以定量刻画传染病发展过程中动力过程的改变,可用于揭示疫情发展的内在规律、快速准确地监测疫情的发展、定量评估管控的效果并预判疫情发展的态势.新型冠状病毒肺炎(COVID-19)疫情发生后,我国政府采取了一系列严格管控措施来控制疫情的蔓延,但管控措施的效果尚无严格的量化分析.采用疫情自然增长模型,本研究提出了一种量化评估管控措施的方法,并估算了无管控措施或管控推迟实施对现存感染者数量的影响.首先根据典型时段的统计数据给出COVID-19在该时段的平均增长率;然后根据平均增长率开展数值试验,比较模型给出的现存感染者总数与实际统计数据的差异,从而对管控效果进行定量评估.结果显示,如果政府对本次疫情未采取管控措施,截至2020年2月18日全国现存感染者将达到1698万~7611万人.如果全国严格管控推迟1天,截至2月18日现存感染者数量将比实际统计数据高出2.7万人(其中湖北地区高出1.2万人);若推迟7天则高出78.5万人(其中湖北地区高出49.3万人).

南海三沙永乐蓝洞是目前已探知的最深海洋蓝洞,洞内70~100 m深的区域存在明显的温度、盐度及溶解氧等跃层结构.海水碳14测年显示该跃层之下的海水年龄约为6000~6600年,这是迄今为止在全球海洋中发现的年龄最古老的海水,对应的跃层也是最古老的.由于蓝洞独特的垂向几何形态,洞内的混合过程接近于分子混合,因此这些海水被很好地封存了数千年.古老海水的形成时间与中全新世发生在雷州半岛的极端冷事件时间大致相同,表明在全新世中期南海北部确实存在极端冷过程.该发现对研究全新世的海洋与气候演变具有重要科学意义.

海洋观测费用高昂,设计科学高效的观测系统可以充分发挥观测的效能。本文以泰国湾高频地波雷达观测系统为例,利用数据同化方法对观测系统进行了最优布局。首先基于FVCOM海洋数值模式建立了泰国湾海域高分辨率三维斜压水动力模式,在此基础上利用一种改进的高效集合卡曼滤波同化方法对岸基高频地波雷达表层海流观测系统开展观测效能评估数值实验。通过观测区域的不同组合方式将3个区域的雷达表层海流数据同化到数值模式中,实验结果表明,岸基高频地波雷达表层海流观测系统可有效降低高分辨数值模式的海流模拟误差。但不同观测区域的组合提供的观测数据对改善海流模拟的作用存在明显差别,泰国湾现有观测系统雷达站位布设方式应进一步优化。本文最后给出了研究区域最优观测站位的布局方案,可作为下一步观测系统进行布局调整的指导。
