| 1 | Wind energy and wave energy resources assessment in the East China Sea and South China Sea显示文摘In this paper,the third-generation wave model WAVEWATCH-III(WW3) was used to simulate the wave field of the East China Sea and South China Sea from January 1988 to December 2009,with wind input of CCMP wind field.Then,the wind energy density and wave energy density were calculated by using the simulated 22-years' wave-field data and CCMP data.By synthetically considering the size of energy density,the frequency of energy level and the stability of energy density,the re-sources of wind energy and wave energy in the East China Sea and South China Sea were analyzed and regionalized.The re-sult can be a guide to searching location of wind & wave power plant. | ZHENG ChongWei ZHUANG Hui LI Xin LI XunQiang | 2012 | Science China(Technological Sciences)2012，55，1： | 122 |
| 2 | An assessment of global ocean wave energy resources over the last 45 a显示文摘Against the background of the current world facing an energy crisis,and human beings puzzled by the problems of environment and resources,developing clean energy sources becomes the inevitable choice to deal with a climate change and an energy shortage.A global ocean wave energy resource was reanalyzed by using ERA-40 wave reanalysis data 1957–2002 from European Centre for Medium-Range Weather Forecasts(ECMWF).An effective significant wave height is defined in the development of wave energy resources(short as effective SWH),and the total potential of wave energy is exploratively calculated.Synthetically considering a wave energy density,a wave energy level probability,the frequency of the effective SWH,the stability and long-term trend of wave energy density,a swell index and a wave energy storage,global ocean wave energy resources were reanalyzed and regionalized,providing reference to the development of wave energy resources such as wave power plant location,seawater desalination,heating,pumping. | ZHENG Chongwei SHAO Longtan SHI Wenli SU Qin LIN Gang LI Xunqiang CHEN Xiaobin | 2014 | Acta Oceanologica Sinica2014，33，1： | 22 |
| 3 | Air-sea heat flux exchange over the South China Sea under different weather conditions before and after southwest monsoon onset in 2000显示文摘With the data observed from the Second SCS Air-Sea Flux Experiment on the Xisha air-sea flux research tower, the radiation budget, latent, sensible heat fluxes and net oceanic heat budgetswere caculated before and after summer monsoon onset. It is discovered that, after summer monsoononset, there are considerable changes in air-sea fluxes, especially in latent heat fluxes and net oceanicheat budget. Furthermre, the analyzed results of five synoptic stages are compared. And the character-istics of the flux transfer during different stages around onset of South China Sea monsoon are discussed.The flux change shows that there is an oceanic heat accumulating process during the pre-onset and thebreak period, as same as oceanic heat losing process during the onset period. Moreover, latent fluxes,the water vapor moving to the continent, even the rainfall appearance in Chinese Mainland also can beinfluenced by southwester. Comparing Xisha fluxes with those obtained from the Indian Ocean and thewestern Pacific Ocean, their differences may be obeerved. It is the reason why SSTs can keep stableover the South China Sea while they decrease quickly over the Arabian Sea and the Bay of Bengal aftermonsoon onset. | Junyue Yan, Huadong Yao, Jianglong Li, Zhiyi Tang, Guorong Jiang, Wenyu Sha, Xunqiang Li, Yiguo Xiao National Climate Center, Beijing 100081, China.

| 4 | Numerical simulations of rip currents off arc-shaped coastlines显示文摘The rip currents induced by waves off arc-shaped coastlines are seriously harmful to humans, but understanding of their characteristics is lacking. In this study, the FUNWAVE model was used to calculate the wave-induced currents in the Haller experiment and the ideal arc-shaped coast similar to Sanya Dadonghai, Hainan Province,China. The results showed that the FUNWAVE model has considerable ability to simulate the rip currents, and it was used to further simulate rip currents off arc-shaped coastlines to investigate their characteristics. The rip currents were found to be stronger as the curvature of arc-shaped coastline increased. Coastal beach slope exerts a significant influence on rip currents; in particular, an overly steep or overly mild slope is not conducive to creating rip currents. Furthermore, the rip currents were found to become weaker as the size of arc-shaped coast decreased. When the height and period of waves increase, the strength of rip currents also increases, and, in some cases, wave heights of 0.4 m may produce dangerous rip currents. | WANG Hong ZHU Shouxian LI Xunqiang ZHANG Wenjing NIE Yu | 2018 | Acta Oceanologica Sinica2018，37，3： | 5 |
| 5 | A theoretical model for the intrusion of the Kuroshio across the continental shelf of East China Sea显示文摘Here we use a two-layer model to study the dynamics of the intrusion of the Kuroshio onto the continental shelf. Results show that the interaction of the Kuroshio water and shelf water produces a stable upwelling zone above 100 m depth northeast of Taiwan, which provides a dynamical explanation to the presence of the cold core previously observed by satellite. The affected shelf water from the interaction has an onshore portion, which turns right and becomes a northward alongshore flow when it moves closer to shore. This implies that the Kuroshio water cannot penetrate deep onto the inner part of the continental shelf, but it generates a strong northward jet that is formed mainly by the shelf water. | ZHANG QingHua QU YuanYuan LI JianKe YIN XunQiang | 2015 | Science China Earth Sciences2015，58，12： | 4 |
| 6 | Development of a fine-resolution atmosphere-wave-ocean coupled forecasting model for the South China Sea and its adjacent seas显示文摘A 72-h fine-resolution atmosphere-wave-ocean coupled forecasting system was developed for the South China Sea and its adjacent seas. The forecasting model domain covers from from 15°S to 45°N in latitude and 99°E to135°E in longitude including the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and the Indonesian seas. To get precise initial conditions for the coupled forecasting model, the forecasting system conducts a 24-h hindcast simulation with data assimilation before forecasting. The Ensemble Adjustment Kalman Filter(EAKF) data assimilation method was adopted for the wave model MASNUM with assimilating Jason-2 significant wave height(SWH) data. The EAKF data assimilation method was also introduced to the ROMS model with assimilating sea surface temperature(SST), mean absolute dynamic topography(MADT) and Argo profiles data. To improve simulation of the structure of temperature and salinity, the vertical mixing scheme of the ocean model was improved by considering the surface wave induced vertical mixing and internal wave induced vertical mixing. The wave and current models were integrated from January 2014 to October 2015 driven by the ECMWF reanalysis 6 hourly mean dataset with data assimilation. Then the coupled atmosphere-wave-ocean forecasting system was carried out 14 months operational running since November 2015. The forecasting outputs include atmospheric forecast products, wave forecast products and ocean forecast products. A series of observation data are used to evaluate the coupled forecasting results, including the wind, SHW, ocean temperature and velocity.The forecasting results are in good agreement with observation data. The prediction practice for more than one year indicates that the coupled forecasting system performs stably and predict relatively accurate, which can support the shipping safety, the fisheries and the oil exploitation. | Junchuan Sun Zexun Wei Tengfei Xu Meng Sun Kun Liu Yongzeng Yang Li Chen Hong Zhao Xunqiang Yin Weizhong Feng Zhiyuan Zhang Yonggang Wang | 2019 | Acta Oceanologica Sinica2019，38，4： | 3 |
| 7 | The Influence of Wave State and Sea Spray on Drag Coefficient from Low to High Wind Speeds显示文摘Ocean waves alter the roughness of sea surface,and sea spray droplets redistribute the momentum flux at the air-sea interface.Hence,both wave state and sea spray influence sea surface drag coefficient.Based on the new sea spray generation function which depends on sea surface wave,a wave-dependent sea spray stress is obtained.According to the relationship between sea spray stress and the total wind stress on the sea surface,a new formula of drag coefficient at high wind speed is acquired.With the analysis of the new drag coefficient,it is shown that the drag coefficient reduces at high wind speed,indicating that the sea spray droplets can limit the increase of drag coefficient.However,the value of high wind speed corresponding to the initial reduced drag coefficient is not fixed,and it depends on the wave state,which means the influence of wave cannot be ignored.Comparisons between the theoretical and measured sea surface drag coefficients in field and laboratory show that under different wave ages,the theoretical result of drag coefficient could include the measured data,and it means that the new drag coefficient can be used properly from low to high wind speeds under any wave state condition. | SHI Jian ZHONG Zhong LI Xunqiang JIANG Guorong ZENG Wenhua LI Yan | 2016 | Journal of Ocean University of China2016，15，1： | 2 |
| 8 | The improvement of the one-dimensional Mellor-Yamada and K-profile parameterization turbulence schemes with the non-breaking surface wave-induced vertical mixing显示文摘Both the level 2.5 Mellor-Yamada turbulence closure scheme(MY) and K-profile parameterization(KPP) are popularly used by the ocean modeling community.The MY and the KPP are improved through including the non-breaking surface wave-induced vertical mixing(Bv),and the improved schemes were tested by using continuous data at the Papa ocean weather station(OWS) during 1961–1965.The numerical results showed that the Bv can make the temperature simulations fit much better with the continuous data from Papa Station.The two improved schemes overcame the shortcomings of predicting too shallow upper mixed layer depth and consequently overheated sea surface temperature during summertime,which are in fact common problems for all turbulence closure models.Statistical analysis showed that the Bv effectively reduced the mean absolute error and root mean square error of the upper layer temperature and increased the correlation coefficient between simulation and the observation.Furthermore,the performance of vertical mixing induced by shear instability and the Bv is also compared.Both the temperature structure and its seasonal cycle significantly improved by including the Bv,regardless of whether shear instability was included or not,especially for the KPP mixing scheme,which suggested that Bv played a dominant role in the upper ocean where the mean current was relatively weak,such as at Papa Station.These results may provide a clue to improve ocean circulation models. | LI Yan QIAO Fangli YIN Xunqiang SHU Qi MA Hongyu | 2013 | Acta Oceanologica Sinica2013，32，9： | 2 |

| 16 | Construction parameters of graded sand-gravel foundation on seismic response law of nuclear safety grade underground corridor显示文摘The treatment of soft soil foundation under nuclear safety grade corridors with graded sand and gravel materials has a good development prospect.It is of great engineering value to explore the influence of construction parameters of graded sand and gravel foundation on the seismic response of gallery structures.Taking the safety grade underground corridor of a nuclear power plant as the engineering background,the equivalent linear method is used to consider the nonlinear dynamic characteristics of graded sand and gravel.The energy transfer boundary is applied at the truncation boundary to simulate the dissipation effect of scattered wave fluctuation energy and the ground motion input.The thicknessless contact element is introduced to consider the contact effect between the corridor structure and the graded sand and gravel foundation,so as to establish the calculation model of the dynamic interaction between the graded sand and gravel foundation and the corridor structure.Furthermore,the influence of the relative compactness and the foundation treatment depth on the seismic response of the corridor structure is studied,and the calculation results of the acceleration response spectrum and relative displacement of the corridor structure are analyzed.The calculation results show that the two construction parameters have different degrees of influence on the seismic response of corridor structure.The research results can provide reference for the engineering design and construction of underground corridors,and provide technical support for the application of graded gravel materials in soft soil foundation treatment. | Yue Li Xunqiang Yin | 2022 | Earthquake Research Advances2022，2，4： | 0 |
| 17 | Relationship between a function of the northward pressure gradient and the Pacific Equatorial Undercurrent显示文摘The Equatorial Undercurrent(EUC) plays an important role in ocean circulation and global climate change. Near the equator, as the Coriolis parameter goes to 0, equatorial currents cannot be described by geostrophy in which the pressure gradient force term is balanced by the Coriolis force term. Many previous studies focus on the relationships between the EUC and El Ni?o-Southern Oscillation(ENSO), the thermocline, sea surface topography, the distribution of equatorial wind stress and other atmosphere-ocean factors. However, little attention has been paid to the northward pressure gradient(NGT), which may also be important to the EUC. The pressure can be regarded as a complex nonlinear function of terms including temperature, salinity and density.This study attempts to reveal the connection between a function of the northward pressure gradient(FNP) and the EUC. The connection is derived from primitive equations, by simplifying the equations with using scaling analysis, and shows that the beta effect may be the main reason why the FNP is important to the EUC. The vertical structure of the EUC can be partially described by the FNP. The NGT has an obvious influence on the EUC while the eastward pressure gradient has a relatively smaller effect. | CHEN Xuan ZHENG Chongwei WU Hui YOU Xiaobao LI Xunqiang WANG Huipeng | 2018 | Acta Oceanologica Sinica2018，37，9： | 0 |
| 18 | A new statistical model of wave heights based on the concept of wave breaking critical zone显示文摘When waves propagate from deep water to shallow water, wave heights and steepness increase and then waves roll back and break. This phenomenon is called surf. Currently, the present statistical calculation model of surf was derived mainly from the wave energy conservation equation and the linear wave dispersion relation, but it cannot reflect accurately the process which is a rapid increasing in wave height near the broken point. So, the concept of a surf breaking critical zone is presented. And the nearshore is divided as deep water zone, shallow water zone, surf breaking critical zone and after breaking zone. Besides, the calculation formula for the height of the surf breaking critical zone has founded based on flume experiments, thereby a new statistical calculation model on the surf has been established. Using the new model, the calculation error of wave height maximum is reduced from 17.62% to 6.43%. | YANG Jiaxuan LI Xunqiang ZHU Shouxian ZHANG Wenjing WANG Lei | 2015 | Acta Oceanologica Sinica2015，34，5： | 0 |
