| 2 | Collision free 4D path planning for multiple UAVs based on spatial refined voting mechanism and PSO approach显示文摘In this paper, a four-dimensional coordinated path planning algorithm for multiple UAVs is proposed, in which time variable is taken into account for each UAV as well as collision free and obstacle avoidance. A Spatial Refined Voting Mechanism(SRVM) is designed for standard Particle Swarm Optimization(PSO) to overcome the defects of local optimal and slow convergence.For each generation candidate particle positions are recorded and an adaptive cube is formed with own adaptive side length to indicate occupied regions. Then space voting begins and is sorted based on voting results, whose centers with bigger voting counts are seen as sub-optimal positions. The average of all particles of corresponding dimensions are calculated as the refined solutions. A time coordination method is developed by generating specified candidate paths for every UAV, making them arrive the same destination with the same time consumption. A spatial-temporal collision avoidance technique is introduced to make collision free. Distance to destination is constructed to improve the searching accuracy and velocity of particles. In addition, the objective function is redesigned by considering the obstacle and threat avoidance, Estimated Time of Arrival(ETA), separation maintenance and UAV self-constraints. Experimental results prove the effectiveness and efficiency of the algorithm. | Yang LIU Xuejun ZHANG Yu ZHANG Xiangmin GUAN | 2019 | Chinese Journal of Aeronautics2019，32，6： | 20 |
| 3 | Thermal cracking of aviation kerosene for scramjet applications显示文摘Thermal cracking of China No.3 aviation kerosene was studied experimentally and analytically under supercritical conditions relevant to regenerative cooling system for Mach-6 scramjet applications. A two-stage heated tube system with cracked products collection/analysis was used and it can achieve a fuel temperature range of 700―1100 K,a pressure range of 3.5―4.5 MPa and a residence time of ap-proximately 0.5―1.3 s. Compositions of the cracked gaseous products and mass flow rate of the kerosene flow at varied temperatures and pressures were obtained experimentally. A one-step lumped model was developed with the cracked mixtures grouped into three categories:unreacted kerosene,gaseous products and residuals including liquid products and carbon deposits. Based on the model,fuel conversion on the mass basis,the reaction rate and the residence time were estimated as functions of temperature. Meanwhile,a sonic nozzle was used for the control of the mass flow rate of the cracked kerosene,and correlation of the mass flow rate gives a good agreement with the measurements. | ZHONG FengQuan FAN XueJun YU Gong LI JianGuo | 2009 | Science China(Technological Sciences)2009，52，9： | 18 |
| 4 | Chinese progress in geomorphometry显示文摘Geomorphometry,the science of digital terrain analysis(DTA),is an important focus of research in both geomorphology and geographical information science(GIS).Given that 70% of China is mountainous,geomorphological research is popular among Chinese scholars,and the development of GIS over the last 30 years has led to significant advances in geomorphometric research.In this paper,we review Chinese progress in geomorphometry based on the published literature.There are three major areas of progress:digital terrain modelling methods,DTA methods,and applications of digital terrain models(DTMs).First,traditional vector-and raster-based terrain modelling methods,including the assessment of uncertainty,have received widespread attention.New terrain modelling methods such as unified raster and vector,high-fidelity,and real-time dynamic geographical scene modelling have also attracted research attention and are now a major focus of digital terrain modelling research.Second,in addition to the popular DTA methods based on topographical derivatives,geomorphological features,and hydrological factors extracted from DTMs,DTA methods have been extended to include analyses of the structure of underlying strata,ocean surface features and even socioeconomic spatial structures.Third,DTMs have been applied to fields including global climate change,analysis of various typical regions,lunar surface and other related fields.Clearly,Chinese scholars have made significant progress in geomorphometry.Chinese scholars have had the greatest international impact in areas including high-fidelity digital terrain modelling and DTM-based regional geomorphological analysis,particularly in the Loess Plateau and the Tibetan Plateau regions. | LV Guonian XIONG Liyang CHEN Min TANG Guoan SHENG Yehua LIU Xuejun SONG Zhiyao LU Yuqi YU Zhaoyuan ZHANG Ka WANG Meizhen | 2017 | Journal of Geographical Sciences2017，27，11： | 14 |
| 5 | Investigation on a vertical radial flow adsorber designed by a novel parallel connection method显示文摘Due to the increasing global demand for industrial gas, the development of large-scale cryogenic air separation systems has attracted considerable attention in recent years. Increasing the height of the adsorption bed in a vertical radial flow adsorber used in cryogenic air separation systems may efficiently increase the treatment capacity of the air in the adsorber. However, uniformity of the flow distribution of the air inside the adsorber would be deteriorated using the height-increasing method. In order to reduce the non-uniformity of the flow distribution caused by the excessive height of adsorption bed in a vertical radial flow adsorber, a novel parallel connection method is proposed in the present work. The experimental apparatus is designed and constructed; the Computational Fluid Dynamics(CFD) technique is used to develop a CFD-based model, which is used to analyze the flow distribution, the static pressure drop and the radial velocity in the newly designed adsorber. In addition, the geometric parameters of annular flow channels and the adsorption bed thickness of the upper unit in the parallelconnected vertical radial flow adsorber are optimized, so that the upper and lower adsorption units could be penetrated by air simultaneously. Comparisons are made between the height-increasing method and the parallel connection method with the same adsorber height. It is shown that using the parallel connection method could reduce the difference between the maximum and minimum radial static pressure drop by 86.2% and improve the uniformity by 80% compared with those of using the height-increasing method. The optimal thickness ratio of the upper and lower adsorption units is obtained as 0.966, in which case the upper and lower adsorption units could be penetrated by air simultaneously, so that the adsorbents in adsorption space could be used more efficiently. | Zhengshu Dai Meng Yu Daozhe Rui Xuejun Zhang Yang Zhao | 2018 | Chinese Journal of Chemical Engineering2018，26，3： | 9 |
| 6 | Physical design of target station and neutron instruments for China Spallation Neutron Source显示文摘The China Spallation Neutron Source(CSNS)is the first accelerator-based multidiscipline user facility to produce pulsed neutrons by tungsten target under collision of a pulsed proton beam with a beam power of 100 kW at a repetition rate of 25 Hz.In this paper,we focus on the physical design of CSNS target station and neutron instruments.Under optimized design,the flat tungsten target and the compact target-moderator-reflector coupling enhance effective cold and thermal neutron output from moderators.Three wing-type moderators supply four different characteristics of neutrons to 19 beamlines primarily for neutron scattering applications.Layout of neutron instruments are conceptually planned for total 20 beamlines,the configuration and specification have been determined for three day-one neutron instruments.All designs are optimized for the Phase I of 100 kW with a upgradable capacity to 500 kW. | WANG FangWei LIANG TianJiao YIN Wen YU QuanZhi HE LunHua TAO JuZhou ZHU Tao JIA XueJun ZHANG ShaoYing | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，12： | 7 |
| 7 | Design and Experimental Research on Seedling Pick-Up Mechanism of Planetary Gear Train with Combined Non-circular Gear Transmission显示文摘Currently, transplanting mechanisms for dryland plug seedlings in China are mainly semiautomatic and have low efficiency. The rotary seedling pick-up mechanism with a planetary gear train for non-uniform intermittent transmission, and a concave and convex locking arc device, has a large rigid impact. To solve these problems, according to the design requirements for a dryland plug seedling transplanting mechanism, a rotary seedling pick-up mechanism of a planetary gear train with combined non-circular gear transmission of incomplete eccentric circular and noncircular gears was proposed. This has the characteristics of two-times greater fluctuation of the transmission ratio in a cycle, and can achieve a non-uniform continuous drive. Through analysis of the working principle of the seedling pick-up mechanism, its kinematics model was established. The human–computer interaction optimization method and self-developed computer-aided analysis and optimization software were used to obtain a set of parameters that satisfy the operation requirements of the seedling pick-up mechanism. According to the optimized parameters, the structure of the seedling pick-up mechanism was designed, a virtual prototype of the mechanism was created, and a physical prototype was manufactured. A virtual motion simulation of the mechanism was performed, high-speed photographic kinematics tests were conducted, and the kinematic properties of the physical prototype were investigated, whereby the correctness of the theoretical model and the optimized design of the mechanism were verified. Further, laboratory seedling pick-up tests were conducted. The success ratio of seedling pick-up was 93.8% when the seedling pick-up efficiency of the mechanism was 60 plants per minute per row, indicating that the mechanism has a high efficiency and success ratio for seedling pick-up and can be applied to a dryland plug seedling transplanter. | Yaxin Yu Jikun Liu Bingliang Ye Gaohong Yu Xuejun Jin Liang Sun Junhua Tong | 2019 | Chinese Journal of Mechanical Engineering2019，32，3： | 7 |
| 8 | Privacy Quantification Model Based on the Bayes Conditional Risk in Location-Based Services显示文摘The widespread use of Location-Based Services(LBSs),which allows untrusted service providers to collect large quantities of information regarding users’locations,has raised serious privacy concerns.In response to these issues,a variety of LBS Privacy Protection Mechanisms(LPPMs)have been recently proposed.However,evaluating these LPPMs remains problematic because of the absence of a generic adversarial model for most existing privacy metrics.In particular,the relationships between these metrics have not been examined in depth under a common adversarial model,leading to a possible selection of the inappropriate metric,which runs the risk of wrongly evaluating LPPMs.In this paper,we address these issues by proposing a privacy quantification model,which is based on Bayes conditional privacy,to specify a general adversarial model.This model employs a general definition of conditional privacy regarding the adversary’s estimation error to compare the different LBS privacy metrics.Moreover,we present a theoretical analysis for specifying how to connect our metric with other popular LBS privacy metrics.We show that our privacy quantification model permits interpretation and comparison of various popular LBS privacy metrics under a common perspective.Our results contribute to a better understanding of how privacy properties can be measured,as well as to the better selection of the most appropriate metric for any given LBS application. | Xuejun Zhang Xiaolin Gui Feng Tian Si Yu Jian An | 2014 | Tsinghua Science and Technology2014，19，5： | 6 |
| 9 | The treatment of black-odorous water using tower bipolar electro-flocculation including the removal of phosphorus,turbidity,sulfion,and oxygen enrichment显示文摘The large amount of municipal wastewater discharged into urban rivers sometimes exceeds the rivers’self-purification capacity leading to black-odorous polluted water.Electro-flocculation has emerged as a powerful remediation technology.Electro-flocculation in a bubble column tower with a bipolar electrode(BPE)was tested in an attempt to overcome the high resistance and weak gas-floatation observed with a monopolar electrode(MPE)in treating such water.The BPE reactor tested had a Ti/Ta2O_(5)-IrO_(2)anode and a graphite cathode with an iron or aluminum bipolar electrode suspended between them.It was tested for its ability to reduce turbidity,phosphate and sulphion and to increase the concentration of dissolved oxygen.The inclusion of the bipolar electrode was found to distinctly improved the system’s conductivity.The system’s electro-flocculation and electrical floatation removed turbidity,phosphate and sulphion completely,and the dissolved oxygen level improved from 0.29 to 6.28 mg/L.An aluminum bipolar electrode performed better than an iron one.Changes in the structure of the microbial community confirmed a significant improvement in water quality. | Huan He Qinjin Yu Chaochao Lai Chen Zhang Muhan Liu Bin Huang Hongping Pu Xuejun Pan | 2021 | Frontiers of Environmental Science & Engineering2021，15，2： | 5 |
| 10 | Source models for the 2016 Mw6.0 Hutubi earthquake, Xinjiang,China: A possible reverse event显示文摘South and north-dipping nodal planes from the U.S. Geological Survey moment tensor solution were used to invert global teleseismic body waves to reveal the source rupture process of the December 8,2016, Mw6.0 Hutubi earthquake. The results show that a compact pattern is the main feature of this event for only one main slip zone located at the hypocenter for both models. The slip distributions are dominated by a nearly pure-thrust fault, and there is no apparent surface rupture. The inversion revealed that the slip zone extends 10 km along strike and 12 km along dip. The released total seismic moment was about 9.0 × 10^(17) Nm, corresponding to a magnitude of Mw6.0. It is difficult to solve for a best-fit rupture plane due to the sample slip pattern without obvious rupture directivity. This makes the farfield teleseismic data not sensitive enough to determine the fault geometric parameters. The source model of the reverse north-dipping plane fits well with the observed waveforms, and the results of the aftershock relocation outline a trend of north-dipping profiles, indicating the possibility of a reverse event. The inverted normal fault beneath the Qigu fold, interpreted by geological and seismic studies,may be the seismogenic fault for this reverse event. | Gang Liu Xuejun Qiao Wei Xiong Yu Zhou Zhaosheng Nie Chuanjia Xia | 2017 | Geodesy and Geodynamics2017，8，5： | 4 |
| 11 | Relationship Between Perisylvian Essential Language Sites and Arcuate Fasciculus in the Left Hemisphere of Healthy Adults显示文摘Essential language sites and the arcuate fasciculus(AF) have been extensively researched. However, the relationship between them remains insufficiently studied,especially in healthy people. Navigated transcranial magnetic stimulation(n TMS) is increasingly used in language mapping. While enjoying the advantage of non-invasiveness, it is also capable of inducing a virtual lesion in the brain. Thus, it offers the possibility of using the virtuallesion method to study the healthy brain. This study combined n TMS and diffusion tensor imaging(DTI)tractography to investigate the relationship between essential language sites and the AF in 30 healthy right-handedvolunteers. A total of 143 essential language sites were identified using n TMS, and a total of 175 AF terminations were identified using DTI tractography. Sixty-six sites had a direct correlation with the AF, accounting for 46% of the total essential language sites. Forty-seven AF terminations harbored essential language sites, accounting for 27% of the total AF terminations. Upon data rendering to the cortical parcellation system, a region-related heterogeneity of the correlation rate was found. This study provides the first data on the relationship between essential language sites and the AF in healthy adults. | Yu Lin Kai Zhang Shuai Li Song Li Jingna Jin Fang Jin Wen Qin Long Hai Meng Zhu Chunshui Yu Zhipeng Liu Tao Yin Xuejun Yang | 2017 | Neuroscience Bulletin2017，33，6： | 3 |
| 12 | Mooring observed mode-2 internal solitary waves in the northern South China Sea显示文摘The mode-2 internal solitary waves(ISWs)generated by mode-2 internal tide(IT)are identified by mooring observations in the northern South China Sea(SCS)from 2016 to 2017.Two mode-2 ISWs with a re-appearance period of 24.9 h observed on 29 and 30 July 2016 are characterized by type-b ISWs.They occurred when the isotherms compressed obviously in the vertical direction.Modal decomposition of IT horizontal currents shows that the vertical compression of the isotherms is mainly caused by diurnal mode-2 IT.The analysis of the role of the density stratification reveals that a deeper and thinner pycnocline is favorable for generation of mode-2 ISWs rather than pycnocline intensity.By comparing the mode-2 nonlinear,dispersion coefficients and the Ursell numbers calculated based on the stratification associated with different kinds of ITs with the observation results,it is shown that the diurnal mode-2 IT plays a crucial role in the generation of the mode-2 ISWs.When the diurnal mode-2 IT interacts with the semidiurnal IT and causes a deeper and thinner pycnocline,the mode-2 ISWs are easily excited. | Liang Chen Xuejun Xiong Quanan Zheng Yeli Yuan Long Yu Yanliang Guo Guangbing Yang Xia Ju Jia Sun Zhenli Hui | 2020 | Acta Oceanologica Sinica2020，39，11： | 3 |
| 13 | Impact of warm mesoscale eddy on tropical cyclone intensity显示文摘The spatial-temporal patterns of tropical cyclone(TC) intensity changes caused by the warm ocean mesoscale eddy(WOME) distribution are evaluated using two sets of idealized numerical experiments. The results show that the TC was intensified and weakened when a WOME was close to and far away from the TC center, respectively.The area where the WOME enhanced(weakened) TC intensity is called the inner(outer) area in this study.Amplitudes of the enhancement and weakening caused by the WOME in the inner and outer area decreased and increased over time, while the ranges of the inner and outer area diminished and expanded, respectively. The WOME in the inner area strengthened the secondary circulation of the TC, increased heat fluxes, strengthened the symmetry, and weakened the outer spiral rainband, which enhanced TC intensity. The effect was opposite if the WOME was in the outer area, and it weakened the TC intensity. The idealized simulation employed a stationary TC, and thus the results may only be applied to TCs with slow propagation. These findings can improve our understanding of the interactions between TC and the WOME and are helpful for improving TC intensity forecasting by considering the effect of the WOME in the outer areas. | Jia Sun Guihua Wang Xuejun Xiong Zhenli Hui Xiaomin Hu Zheng Ling Long Yu Guangbing Yang Yanliang Guo Xia Ju Liang Chen | 2020 | Acta Oceanologica Sinica2020，39，8： | 3 |
| 14 | Effect of Different Sowing Dates in South Henan 's Rice-growing Areas on the Growth and Yield of Ratoon Rice显示文摘In order to determine the optimal sowing date of ratoon rice in South Henan's rice-growing areas,this paper performs a comparative analysis of rice growth process,seedling quality and yield of first season rice and ratoon rice under different sowing date treatments. The results show that under climatic conditions( 2014),by using dry seedling cultivation in a small plastic shed,the growth of seedling sown on February21 was affected,while the sowing treatments from March 1 to April 11 can breed normal seedlings,and in this period,the maturity period of first season rice was delayed with prolonged sowing date,and ratoon rice yield declined with prolonged sowing date( total production of rice sown on 11 March reaching a peak). Thus,it is considered that the optimal sowing date of ratoon rice in South Henan's rice-growing areas is mid-March. | Xiangchen LIU Daqing FENG Guilong YU Haiying ZHAO Li QIAO Yanting LI Xuejun FAN Mingcheng LIU Qiuju ZHANG | 2016 | Asian Agricultural Research2016，8，2： | 3 |
| 15 | Structural optimization of deflector within air-water direct contact tank based on uniform design显示文摘An appropriate microenvironment for preserving cultural relics is essential,and the air-water direct contact tech-nology is utilized to create the microenvironment recently.The influence of a deflector in a tank was numerically investigated based on uniform design method to improve the heat and mass transfer and pressure drop perfor-mance of the air-water direct tank.In this study,a simplified CFD-based model was established and validated between airstream and water surface within the tank,to analyze the heat and mass transfer and pressure drop processes.Meanwhile,regression models of the heat transfers rate,mass transfer rate and pressure drop were developed by uniform design method based on three parameters:installation position,tilt angle,and height of the deflector,in order to analyze the influences of these three parameters on the heat and mass transfer and pressure drop of the tank.Finally,all three optimal structural parameters of the deflector were obtained based on the proposed comprehensive evaluation index using a genetic algorithm.The results showed that the model established for air-water direct contact adopted well to predict the heat and mass transfer and pressure drop per-formance between airstream and still water surface.Furthermore,the results found that the flow field inside the water tank was affected by the deflector’s structure,which affected the heat and mass transfer performance.The simulation results suggested that the deflector’s optimal structural parameters are 8 mm of installation position,88°of tilt angle and 19 mm of height,respectively,within a given extent in this study. | Ning Wang Meng Yu Writing-review&editing Xuejun Zhang Yang Zhao | 2022 | Energy and Built Environment2022，3，2： | 2 |
| 16 | Reliability analysis based on a novel density estimation method for structures with correlations显示文摘Estimating the Probability Density Function(PDF) of the performance function is a direct way for structural reliability analysis,and the failure probability can be easily obtained by integration in the failure domain.However,efficiently estimating the PDF is still an urgent problem to be solved.The existing fractional moment based maximum entropy has provided a very advanced method for the PDF estimation,whereas the main shortcoming is that it limits the application of the reliability analysis method only to structures with independent inputs.While in fact,structures with correlated inputs always exist in engineering,thus this paper improves the maximum entropy method,and applies the Unscented Transformation(UT) technique to compute the fractional moments of the performance function for structures with correlations,which is a very efficient moment estimation method for models with any inputs.The proposed method can precisely estimate the probability distributions of performance functions for structures with correlations.Besides,the number of function evaluations of the proposed method in reliability analysis,which is determined by UT,is really small.Several examples are employed to illustrate the accuracy and advantages of the proposed method. | Baoyu LI Leigang ZHANG Xuejun ZHU Xiongqing YU Xiaodong MA | 2017 | Chinese Journal of Aeronautics2017，30，3： | 2 |
| 17 | Hybrid coordinated strategy of downlink coordinated multi-point transmission显示文摘Coordinated multi-point(CoMP) transmission is put forward in the long term evolution-advanced(LTE-A) system to improve both average and cell-edge throughput. CoMP-joint processing(JP) scheme can get a larger cell-edge throughput and a lower bit error rate(BER) than the CoMP-coordinated beamforming(CB) scheme, but it also has higher complexity due to data sharing. A hybrid coordinated strategy with parameter α, which indicates the proportion of users employing the CoMP-JP scheme,is proposed to apply the CoMP-JP scheme to improve the poorer communication quality of cell edge and employ the CoMP-CB scheme for other users to enhance average throughput and spectral efficiency. This paradigm selects users defined by the certain threshold of signal to interference plus noise power ratio(SINR)corresponding to the parameter α to the CoMP-JP scheme. This paper compares the BER performance between the block diagonalization(BD) based precoding and the linear precoders by maximizing signal to leakage and noise ratio(SLNR), and also indicates that the SLNR based precoding algorithm gets lower BER than the BD based precoding algorithm with certain signal-to-noise ratios(SNRs). Finally, this paper discusses that the system performance is partially affected by the percentage of CoMP-JP users and concludes that 50% of users sorted to communicate under the CoMP-JP scheme will reach the best system performance. | Zhuoming Li Yuqi Liu Yu Zhang Peng Wang Chunyang Tian Xuejun Sha | 2015 | Journal of Systems Science & Complexity2015，28，5： | 2 |
| 18 | Bright photon-pair source based on a silicon dual-Mach-Zehnder microring显示文摘Single photons and photon pairs are typically generated by spontaneous parametric down conversion or quantum dots;however,spontaneous four-wave mixing(SFWM)in silicon microring resonators[1]is also an appealing source of entangled photons,offering a strong cavity-enhanced nonlinear interactions while maintaining features,such as compact,simple to fabricate,and allowing for thermal tuning.However,silicon ring-resonators usually suffer from a trade-off between providing a high pair generation rate(PGR)and high extraction efficiency.To achieve high PGR,devices are generally operated with the signal and idler photons in the undercoupling regime and pump photons at the critical coupling point,while high extraction rates require the converted photons to be overcoupled.Therefore,the optimal conditions for achieving maximal output photon pair flux are critical coupling for the pump photons and overcoupling for the converted photons[2,3]. | Chao Wu YingWen Liu XiaoWen Gu XinXin Yu YueChan Kong Yang Wang XiaoGang Qiang JunJie Wu ZhiHong Zhu XueJun Yang Ping Xu | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，2： | 2 |
| 19 | Olfactory and gustatory dysfunctions of COVID-19 patients in China:A multicenter study显示文摘Introduction:With the spread of the epidemic worldwide,an increasing number of doctors abroad have observed the following atypical symptoms of coronavirus disease 2019(COVID-19):olfactory or taste disorders.Therefore,clarifying the incidence and clinical characteristics of olfactory and taste disorders in Chinese COVID-19 patients is of great significance and urgency.Materials and Methods:A retrospective study was conducted,which included 229 severe acute respiratory syndrome coronavirus 2 confirmed patients,through face-to-face interviews and telephone follow-up.Following the completion of questionnaires,the patients participating in the study,were categorized according to the degree of olfactory and taste disorders experienced,and the proportion of each clinical type of patient with olfactory and taste disorders and the time when symptoms appeared were recorded.Results:Among the 229 patients,31(13.54%)had olfactory dysfunction,and 44(19.21%)had gustatory dysfunction.For the patients with olfactory dysfunction,6(19.35%)developed severe disease and became critically ill.Olfactory dysfunction appeared before the other symptoms in 21.43%of cases.The proportion of females with olfactory and gustatory dysfunction was higher than that of males(P<0.001).Conclusions:The incidence of olfactory and gustatory dysfunction was much lower than that reported abroad;the prognosis of patients with olfactory dysfunction is relatively favorable;olfactory and gustatory dysfunction can be used as a sign for early screening;females are more prone to olfactory and gustatory dysfunction. | Jianhui Li Yi Sun Enqiang Qin Hu Yuan Mingbo Liu Wenqi Yi Zhu Chen Chengcheng Huang Fengjie Zhou Ruiyao Chen Leibo Zhang Ning Yu Qiong Liu Xuejun Zhou Jingjing He Boyu Li Fusheng Wang Changliang Yang Shiming Yang | 2022 | World Journal of Otorhinolaryngology-Head and Neck Surgery2022，8，4： | 2 |
| 20 | Existence, morphology and structure of the Yellow Sea Warm Current Branch approaching waters offshore Qingdao, China显示文摘In this study, we focused on full-region cruise survey data, near-bottom continuous mooring observations and sea surface wind products from the western South Yellow Sea in winter; after ensuring the data reliability and accuracy, we processed and analyzed the data. Image resolution experiments were carried out to determine the lowest recognition resolutions for all image types, which represent the resolution characteristics of the data. The existence of a warm water tongue originating from the Yellow Sea Warm Current(YSWC) that approached waters offshore Qingdao was confirmed. For the first time, a high salinity water tongue, corresponding to the warm water tongue, was described and found to be more representative of the YSWC branch path. This warm tongue is a sign of the branch originating from the YSWC, which we defined as the Yellow Sea Warm Current Branch approaching waters offshore Qingdao(YSWC-QDB). The pattern of the warm and salty water tongues showed remarkable rear, branching middle, shrinking neck and expanding top regions. These patterns showed a temporal feature of the tongues, and were the result of multi-temporal branches in front of the YSWC main section as well as the YSWC-QDB crossing the southwestward path of the extension of the North Shandong Coastal Current flowing along the southeast coast of the Shandong Peninsula(NSCC-SESE). Analysis using mooring data at a sensitive and representative station also showed the existence of the YSWC-QDB. It is a probabilistic event that manifests as a northwestward flow that decreases gradually from the bottom to the surface in the early cold air transit stage and consistent in the whole water column profile in the later stage. It varies quasi-periodically with weather processes. It also transports some of the YSWC water stored in the entrance area of the Bohai and Yellow seas under winter wind conditions to the western South Yellow Sea as a compensatory current. This current, caused by northerly winds, especially northwest winds and obstruction of the NSCC-SESE, was present, and strong water reduction and compensation caused significant residual sea level oscillations. The compensatory current, if caused by strong northwest wind,began to appear when its direction was opposite to the wind direction. In addition, confirmation of the YSWC-QDB provides an oceanographic basis for the short cooling time and rapid warming in the Qingdao area in winter. This research provides a basis for further studies of the YSWC-QDB at high spatial and temporal resolutions using large sea surface datasets. For monsoon basin dynamics, this study can also be extended to the whole Bohai and Yellow seas and closed or semi-closed basins on the continental margin. | Xuejun XIONG Xiaomin HU Yanliang GUO Long YU Liang CHEN Yuhuan XUE | 2019 | Science China Earth Sciences2019，62，7： | 2 |
