| 2 | An Eddy-Permitting Oceanic General Circulation Model and Its Preliminary Evaluation显示文摘An eddy-permitting, quasi-global oceanic general circulation model, LICOM (LASG/IAP (State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics) Climate System Ocean Model), with a uniform grid of 0.5? × 0.5? is established. Forced by wind stresses from Hellerman and Rosenstain (1983), a 40-yr integration is conducted with sea surface temperature and salinity being restored to the Levitus 94 datasets. The evaluation of the annual mean climatology of the LICOM control run shows that the large-scale circulation can be well reproduced. A comparison between the LICOM control run and a parallel integration of L30T63, which has the same framework but a coarse resolution, is also made to con?rm the impact of resolution on the model performance. On account of the reduction of horizontal viscosity with the enhancement of the horizontal resolution, LICOM improves the simulation with respect to not only the intensity of the large scale circulations, but also the magnitude and structure of the Equatorial Undercurrent and South Equatorial Current. Taking advantage of the ?ne grid size, the pathway of the Indonesian Through?ow (ITF) is better represented in LICOM than in L30T63. The transport of ITF in LICOM is more convergent in the upper layer. As a consequence, the Indian Ocean tends to get warmer in LICOM. The poleward heat transports for both the global and individual basins are also signi?cantly improved in LICOM. A decomposed analysis indicates that the transport due to the barotropic gyre, which primarily stands for the barotropic e?ect of the western boundary currents, plays a crucial role in making the di?erence. | 刘海龙 张学洪 李薇 俞永强 宇如聪 | 2004 | Advances in Atmospheric Sciences2004，21，5： | 68 |

| 4 | Arctic Sea Ice Decline Intensified Haze Pollution in Eastern China显示文摘Air quality in eastern China has becoming more and more worrying in recent years, and haze is now No.1 air pollution issue. Results in this study show the decreasing Arctic sea ice(ASI) is an important contributor to the recent increased haze days in eastern China. The authors find that the number of winter haze days(WHD) in eastern China is strongly negatively correlated with the preceding autumn ASI during 1979–2012, and about 45%– 67% of the WHD interannual to interdecadal variability can be explained by ASI variability. Following previous studies on the impact of ASI loss on the northern hemisphere climate, the authors' studies further reveal that the reduction of autumn ASI leads to positive sea-level pressure anomalies in mid-latitude Eurasia, northward shift of track of cyclone activity in China, and weak Rossby wave activity in eastern China south of 40N during winter season. These atmospheric circulation changes favor less cyclone activity and more stable atmosphere in eastern China, leading to more haze days there. Furthermore, the patterns of circulation changes associated with autumn ASI and WHD are in very good agreement over the East Asia, particularly in eastern China. The authors suggest that haze pollution may continue to be a serious issue in the near future as the decline of ASI continues under global warming. | WANG Hui-Jun CHEN Huo-Po LIU Jiping | 2015 | Atmospheric and Oceanic Science Letters2015，8，1： | 43 |
| 5 | Relationship between the Asian-Pacific oscillation and the tropical cyclone frequency in the western North Pacific显示文摘The relationship between the Asian-Pacific oscillation (APO) and the tropical cyclone frequency over the western North Pacific (WNP) in summer is preliminarily investigated through an analysis of ob- served data. The result has shown clearly that APO is significantly and positively correlated to the tropical cyclone frequency in the WNP. If APO is above (below) the normal in summer, more (less) tropical cyclones will tend to appear in the WNP. The present study also addresses the large-scale at- mospheric general circulation changes underlying the linkage between APO and the WNP tropical cy- clone frequency. It follows that a positive phase of summer APO is concurrent with weakened as well as northward and eastward located western Pacific subtropical high (WPSH), low-level convergence and high-level divergence, and reduced vertical zonal wind shear in the WNP, providing favorable envi- ronment for the tropical cyclone genesis, and thus more tropical cyclones will come into being, and vice versa. | ZHOU BoTao1, CUI Xuan2 & ZHAO Ping3 1 Laboratory for Climate Studies, National Climate Center, China Meteorological Administration, Beijing 100081, China 2 National Meteorological Center, China Meteorological Administration, Beijing 100081, China 3 Chinese Academy of Meteorological Sciences, China Meteorological Administration, Beijing 100081, China | 2008 | Science China Earth Sciences2008，51，3： | 40 |
| 6 | Cell membrane-based nanoparticles: a new biomimetic platform for tumor diagnosis and treatment显示文摘Taking inspiration from nature, the biomimetic concept has been integrated into drug delivery systems in cancer therapy. Disguised with cell membranes, the nanoparticles can acquire various functions of natural cells. The cell membrane-coating technology has pushed the limits of common nano-systems(fast elimination in circulation) to more effectively navigate within the body. Moreover, because of the various functional molecules on the surface, cell membrane-based nanoparticles(CMBNPs) are capable of interacting with the complex biological microenvironment of the tumor. Various sources of cell membranes have been explored to camouflage CMBNPs and different tumor-targeting strategies have been developed to enhance the anti-tumor drug delivery therapy. In this review article we highlight the most recent advances in CMBNP-based cancer targeting systems and address the challenges and opportunities in this field. | Ruixiang Li Yuwei He Shuya Zhang Jing Qin Jianxin Wang | 2018 | Acta Pharmaceutica Sinica B2018，8，1： | 36 |

| 8 | On the Onset of the South China Sea Summer Monsoon in 1998显示文摘Through analyzing the NCEP/ NCAR reanalysis data, the satellite observational data and the ATLAS-2 mooring buoy observational data, it is shown that May 21 is the onset date of the South China Sea summer monsoon in 1998. There were abrupt variations in the general circulation pattern at the lower troposphere and the upper troposphere, in upper hi stream location and in the convection and rainfall over the South China Sea region corresponding to the outbreak of the South China Sea summer monsoon. It is also indicated that there was rainfall in the southern China coastal region before onset of summer monsoon, but it resulted from the (cold) front activity and cannot be regarded as the sign of summer monsoon outbreak in the South China Sea. | 李崇银 吴静波 | 2000 | Advances in Atmospheric Sciences2000，17，2： | 23 |
| 9 | Land-atmosphere-ocean coupling associated with the Tibetan Plateau and its climate impacts显示文摘This paper reviews recent advances regarding land-atmosphere-ocean coupling associated with the Tibetan Plateau(TP)and its climatic impacts.Thermal forcing over the TP interacts strongly with that over the Iranian Plateau,forming a coupled heating system that elevates the tropopause,generates a monsoonal meridional circulation over South Asia and creates conditions of large-scale ascent favorable for Asian summer monsoon development.TP heating leads to intensification and westward extension(northward movement)of the South Asian High(Atlantic Intertropical Convergence Zone),and exerts strong impacts on upstream climate variations from North Atlantic to West Asia.It also affects oceanic circulation and buoyancy fields via atmospheric stationary wave trains and air-sea interaction processes,contributing to formation of the Atlantic Meridional Overturning Circulation.The TP thermal state and atmospheric-oceanic conditions are highly interactive and Asian summer monsoon variability is controlled synergistically by internal TP variability and external forcing factors. | Yimin Liu Mengmeng Lu Haijun Yang Anmin Duan Bian He Song Yang Guoxiong Wu | 2020 | National Science Review2020，7，3： | 21 |
| 10 | Numerical simulation for the coupling effect of local atmospheric circulations over the area of Beijing,Tianjin and Hebei Province显示文摘Using the model system MM5.V3 and multi-layer grid nesting technique, we have done a multi-scale numerical simulation over the area of Beijing, Tianjin and Hebei Province to analyze the temperature and wind field there and study its local circulations. The results show a coupling effect of Urban Heat Island Circulation (UHIC), Mountain Valley Breeze (MVB) and Sea Land Breeze (SLB) occurs in this area when the synoptic system is weak. The SLB can penetrate deep into the mainland for about 200 km when it is blooming. MVB can extend to south and cover almost the whole plain area in Beijing. Both MVB and SLB are diurnal periodical; meanwhile the phase of MVB drops behind that of SLB for about six hours. As a local circulation, the UHIC weakens the two circulations above, and it also has a diurnal period. As a result, the coupling effect of circulations reveals not only different features in spring-summer period and autumn-winter period in a year but also the difference between early morn- ing to noonday and afternoon to night in a day. We noted the diffusion of contamination over the area around Beijing, and found the steady presence of a transport routine of contamination over North-China throughout the year caused by the Coupling Effect mentioned above. This find is important for studying the environment pollution in this area. | LIU ShuHua LIU ZhenXin LI Ju WANG YinChun MA YanJun SHENG Li LIU HePing LIANG FuMing XIN GuoJun WANG JianHua | 2009 | Science China Earth Sciences2009，52，3： | 20 |

| 12 | The East Asian summer monsoon circulation anomaly index and its interannual variations显示文摘Based on the concept of East Asia-Pacific (EAP) teleconnection which influences East Asian summer monsoon, an index for East Asian summer monsoon circulation anomaly was defined and it was pointed out that this index can describle the interannual variation character of summer climate in East Asia, especially in the Yangtze River and Huaihe River Valley. | Gang Huang Zhongwei Yan | 1999 | Chinese Science Bulletin1999，44，14： | 18 |
| 13 | Integration of Growing Milk Vetch in Winter and Reducing Nitrogen Fertilizer Application Can Improve Rice Yield in Double-Rice Cropping System显示文摘To study whether integrative fertilization [growing milk vetch in winter and reducing the dose of chemical nitrogen(N) fertilizer] can improve rice yield, and to reveal the underlying regulatory mechanisms for integrative fertilization, a three-year field trial including two treatments, milk vetch-rice-rice(MRR) and winter fallow-rice-rice(FRR), was conducted in 2010, 2011 and 2012.Our results demonstrated that the MRR treatment could significantly improve rice yield compared with the FRR treatment, especially when the application ratio of milk vetch and chemical fertilizer was 1:2.MRR treatment increased the effective panicle number and the spikelet number per panicle.In addition, a higher tillering number, leaf area index, photosynthetic-potential and photosynthetic-potential to grain ratio were observed in MRR treatment, which could provide enough dry matter for yield formation.Moreover, in MRR treatment, we discovered a higher transportation ratio and transformation ratio of dry matter in culm and leaves, and a stronger total sink capacity and spikelet-root bleeding intensity at the heading stage and 15 d after heading.Furthermore, the MRR treatment showed higher total N, phosphorus and potassium uptakes than FRR treatment, which was associated with the higher root dry weight in each soil layers.These results suggest that growing milk vetch in winter can improve rice yield under less chemical N fertilizer application, which is due to the improvement of soil nutrient status and the increased of rice root growth and development. | ZHOU Chun-huo ZHAO Zun-kang PAN Xiao-hua HUANG Shan TAN Xue-ming WU Jian-fu SHI Qing-hua | 2016 | Rice science2016，23，3： | 18 |
| 14 | A HEMODYNAMIC MODEL AND A MATHEMATICAL METHOD TO CALCULATE THE DYNAMICS INDEX FOR CEREBRAL CIRCULATION显示文摘The dynamics indexes,playing an important role in the cerebral circulation,will be changed significantly compared with their normal range in many cerebrovascular disease.The geometrical parameters of cerebrovascular may be detected by DSA or MRA scan,but the hemodynamic parameters,such as,blood flow,artery resistance and compliance must be calculated by building hemodynamics model. The cerebral circular system that has four entrances for blood flow(two carotid and two vertebral arteries)and three communicating arteries is much different from the systematic ststem which has only one entrance,ic.,the aortic.The purpose of this study is to set up a hemodynamics model with lumped parameters to describe the cerebral circulation.From this model,we get its governing equations and present a new method to calculate the hemodynamics indexes in clinical application. | Ding Guang-hongDepartment of Applied Mechanics, Fudan University, Shanghai 200433, P.

| 15 | On the Huanghai (Yellow) Sea circulation:a review by current measurements显示文摘The Huanghai (Yellow) Sea circulations suggested in the past were constructed mostly based on hydrographic data or simple numerical models, and were not rigorously compered with direct current measurements. Ourpresent understanding of the Huanghai Sea circulation is still very poor and superficial. To evaluate our present knowledge about the circulation and to sketch a more realistic circulation pattern, the previous studies on the circulation arebriefly reviewed and directly measured current data collected in the past are revisited. The Huanghai Sea Warm Current and the northeastward extension in summer of the Changjiang diluted water are paid more attention to, which arethe major currents of the basic circulation, and then attempted to sketch the Huanghai Sea circulation by synthesizinghydrography and current data. The Huanghai Sea circulation is not considered to be persistent since the thin water column, less than 100 m, responds quickly and sensitively to external driving forces. Directly measured current data showthat saline water originating from the Kuroshio water turns clockwise around Cheju-do throughout the year and eventually joins the Tsushima Warm Current at the western channel of the Korea Strait. This clockwise current is called theCheju Warm Current. The current data do not support the persistent existence of the Huanghai Sea Warm Current,which has ho believed to supply heat and salt to the Huanghai Sea throughout the year. However, a northward flowis generated intermittently during the weakening phase of cold air outbreaks in winter. The northeast extension of theChangjiang diluted water in summer is evidenced by satellite-tracked surface drifters. | Heung-Jae Lie(Physical Oceanography Dvision, Korea Ocean Research and Development Institute, P.O.

| 16 | Diagnostic Study on Seasonality and Interannual Variability of Wind Field显示文摘Based on NCEP/ NCAR reanalysis data during 1980-1994, seasonality and interannual variability of the horizontal wind field are studied. It is shown that: (1) In the lower troposphere,there exist regions with maximum of seasonality in the tropics, the subtropics and high latitudes,which is called the tropicat subtropical and temperate-frigid monsoon region respectively. In theupper troposphere, the subtropical monsoon combines with the tropical monsoon as anonseparably planetary monsoon system. In the stratosphere, there is a belt with very largeseasonality in each hemisphere caused by the inversely seasonal circulation and by the establishment and collapse of the night jet. (2) Seasonal variation of the large-scale monsoon may generallybe attributed to that of the zonal wind, however, seasonal variation of the meridional wind is ofgreat importanee in East Asian monsoon region. (3) In monsoon region, interannual variability ofthe atmospheric general circulation is closely related to seasonal variation of monsoon, while in thetropical Pacific, it may considerably be influenced by the external factors such as sea surface temperature (SST) anomalies associnted with El Nino or La Nina event. Moreover, interannual variability undetgoes a pronounced annual cycle. | 薛峰 曾庆存 | 1999 | Advances in Atmospheric Sciences1999，16，4： | 15 |
| 17 | A Comparison between Numerical Simulations of Forced Local Hadley (Anti-Hadley) Circulation in East Asian and Indian Monsoon Regions显示文摘Two numerical simulations of forced local Hadley circulation are carried out based on a linear diagnostic equation to provide an insight into the mechanisms of monsoon evolution in different monsoon regions. One simulation is for the zonal mean Hadley circulation over East Asia (from 95°E to 122.5°E), another over India (from 70°E to 85°E). With the NCEP / NCAR re-analysis data re-processed by Chinese Academy of Science in Beijing. the former simulation displays a dominant anti-Hadley circulation pattern over East Asia at 1200 UTC May 1. l994. The simulated circulation pattern is consistent well enough with the circulation pattern plotted directly from the data for lack of the radiation information at each level. Although the simulation over India is not as good as that over East Asia. a dominant Hadley circulation pattern is obvious as data show. Further analysis shows that the defective simulation over India is due to foe presence of slatically unstable condition at some grid points in the lower troposphere. This circumstance slightly violates the hydrodynamic stability criterion required by the elliptic diagnostic equation for the forced circulation. Since the simulations are reliable enough compared with the given data, the linear equation facilitates a systematic assessment of relative importance of each internally forcing process. The assessment shows that among the internal processes, the horizontal temperature advections account obviously for the Hadley (anti-Hadley) circulation over India (East Asia) at 1200 UTC May 1. 1994 in addition to the process associated with the latent heat releasing. The calculation of latent heat energy is a little bit unreliable due to the unclear cloud physics in the convection processes and the less accurate humidity data. These preliminary results are consistent with the results of previons studies which show that the feature of the seasonal warming in the upper troposphere and the corresponding processes are part of key processes closely related to the evolution of the summer monsoon over East Asia and India. | 袁卓建 王同美 贺海晏 罗会邦 郭裕福 | 2000 | Advances in Atmospheric Sciences2000，17，4： | 15 |
| 18 | Evolution mechanisms of the intraseasonal oscillation associated with the Yangtze River Basin flood in 1998显示文摘With 1998 NCEP reanalysis data and the linear diagnostic equation for local me- ridional circulation, four main processes and the boundary effects with relatively large contribu- tions to the intraseasonal oscillation of the vertical branches of the East Asian meridional circula- tion are quantitatively identified among all the processes involved in the quasi-primitive equations used in the derivation of the linear diagnostic equation. The numerical results show that the main processes with maximal contributions in the lower latitudes include the latent heating and vertical transports of sensible heat. These processes are mainly associated with the tropical convective activities and result in the low-frequency cyclones in the lower latitudes. The main processes with maximal contributions in the higher latitudes are the horizontal transports of westerly momentum and horizontal temperature advections. These processes are mainly associated with the fluctua- tions in the westerlies and result in the low-frequency cyclones in the higher latitudes. The low-frequency cyclones propagating away from lower latitudes not only interact with those from higher latitudes to enhance the lifting of the moist air in the Yangtze River Basin (YRB), but also leave room for the development of the low-frequency anticyclones over the South China Sea (SCS). The southwesterly in the northwestern quadrant of the SCS anticyclones provides the YRB with abundant moisture. This favorable moisture condition along with the enhanced rising motion in the YRB leads to the extraordinary flood in 1998. | CHEN Guixing LI Weibiao YUAN Zhuojian WEN Zhiping | 2005 | Science China Earth Sciences2005，48，7： | 13 |
| 19 | Physiopathology of splanchnic vasodilation in portal hypertension显示文摘In liver cirrhosis, the circulatory hemodynamic alterations of portal hypertension signifi cantly contribute to many of the clinical manifestations of the disease. In the physiopathology of this vascular alteration, mesen- teric splanchnic vasodilation plays an essential role by initiating the hemodynamic process. Numerous studies performed in cirrhotic patients and animal models have shown that this splanchnic vasodilation is the result of an important increase in local and systemic vasodilators and the presence of a splanchnic vascular hyporesponsiveness to vasoconstrictors. Among the molecules and factors known to be potentially involved in this arterial vasodilation, nitric oxide seems to have a crucial role in the physiopathology of this vascular alteration. However, none of the wide variety of mediators can be described as solely responsible, since this phenomenon is multifactorial in origin. Moreover, angiogenesis and vascular remodeling processes alsoseem to play a role. Finally, the sympathetic nervous system is thought to be involved in the pathogenesis of the hyperdynamic circulation associated with portal hypertension, although the nature and extent of its role is not completely understood. In this review, we discuss the different mechanisms known to contribute to this complex phenomenon. | María Martell Mar Coll Nahia Ezkurdia Imma Raurell Joan Genescà | 2010 | World Journal of Hepatology2010，2，6： | 13 |
| 20 | The relationship between the thermohaline circulation and climate variability显示文摘The long-term integration with the Global Ocean-Atmosphere-Land System model of the State Key Laboratory of Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), Institute of Atmospheric Physics(IAP), Chinese Academy of Sciences has been used in the investigations on the relationship between the thermohaline circulation and climate variability. The results show that the strength of the North Atlantic Thermohaline circulation (THC) is negatively correlated with the North Atlantic Oscillation (NAO). Based on this kind of relationship, and also the instrument-measured climate record such as air pressure and sea surface temperature, the activity of the thermohaline circulation during the 20th century has been evaluated. The inferred variations of the strength of the THC is that, during two multi-decadal periods of 1867-1903 and 1934-1972, the THC is estimated to have been running stronger, whereas during the two periods of 1904-1933 and 1973-1994, it appears to have been weaker. | ZHOU Tianjun ZHANG Xuehong WANG Shaowu | 2000 | Chinese Science Bulletin2000，45，11： | 13 |
