| 2 | A quasi-global 1/10° eddy-resolving ocean general circulation model and its preliminary results显示文摘In this study,a quasi-global(excluding the Arctic Ocean) eddy-resolving ocean general circulation model(OGCM) is established based on the latest version of the LASG/IAP Climate system Ocean Model(LICOM2.0).The horizontal resolution and vertical resolution are increased to 1/10° and 55 layers,respectively.Forced by the surface fluxes from the reanalysis and observed data,the model has been integrated for approximately 20 model years(20 a).During the last 8 a,the model is driven by daily mean wind stresses from QuikSCAT and heat fluxes from reanalysis data from 2000 to 2007.The basic performance of the OGCM is analyzed using the last 8 a simulation output.Compared with the simulation of the coarse-resolution OGCM,the eddy-resolving OGCM not only better simulates the spatial-temporal features of mesoscale eddies and the paths and positions of western boundary currents but also reproduces the large meander of the Kuroshio Current and its interannual variability.Another aspect,namely,the complex structures of equatorial Pacific currents and currents in the coastal ocean of China,are better captured due to the increased horizontal and vertical resolution. | YU YongQiang LIU HaiLong LIN PengFei | 2012 | Chinese Science Bulletin2012，57，30： | 18 |
| 3 | The HY-2 satellite and its preliminary assessment显示文摘The HY-2 satellite was successfully launched on 16 August 2011.It carried four microwave instruments into space for operationally observing dynamic ocean environment parameters on a global scale.The HY-2 satellite altimeter provides sea surface height(SSH),significant wave height(SWH),sea surface wind(SSW)speed,and polar ice sheet elevation,while the HY-2 satellite scatterometer provides SSW fields.At the same time,other oceanic and atmospheric parameters such as sea surface temperature(SST)and wind speed,water vapor and liquid water content can also be obtained by its onboard scanning microwave radiometer.In this paper,we show the data processing methods of the HY-2 satellite’s payloads.The preliminary results show that wind vector,SSH,SWH,and SST conform to the designed technical specifications. | Xingwei Jiang Mingsen Lin Jianqiang Liu Youguang Zhang Xuetong Xie Hailong Peng Wu Zhou | 2012 | International Journal of Digital Earth2012，5，3： | 10 |
| 4 | First six months quality assessment of HY-2A SCAT wind products using in situ measurements显示文摘The first Chinese microwave ocean environment satellite HY-2A,carrying a Ku-band scatteromenter(SCAT),was successfully launched in August 2011.The first quality assessment of HY-2A SCAT wind products is presented through the comparison of the first 6 months operationally released SCAT products with in situ data.The in situ winds from the National Data Buoy Center(NDBC)buoys,R/V Polarstern,Aurora Australis,Roger Revelle and PY30-1 oil platform,were converted to the 10 m equivalent neutral winds.The temporal and spatial differences between the HY-2A SCAT and the in situ observations were limited to less than 5min and 12.5 km.For HY-2A SCAT wind speed products,the comparison and analysis using the NDBC buoys yield a bias of–0.49 m/s,a root mean square error(RMSE)of 1.3 m/s and an increase negative bias with increasing wind speed observation above 3 m/s.Although less accurate of HY-2A SCAT wind direction at low winds,the RMSE of 19.19 with a bias of 0.92 is found for wind speeds higher than 3 m/s.These results are found consistent with those from R/Vs and oil platform comparisons.Moreover,the NDBC buoy comparison results also suggest that the accuracy of HY-2A SCAT winds is consistent over the first half year of 2012.The encouraging assessment results over the first 6 months show that wind products from HY-2A SCAT will be useful for scientific community. | WANG He ZHU Jianhua LIN Mingsen HUANG Xiaoqi ZHAO Yili CHEN Chuntao ZHANG Youguang PENG Hailong | 2013 | Acta Oceanologica Sinica2013，32，11： | 10 |
| 5 | LICOM Model Datasets for the CMIP6 Ocean Model Intercomparison Project显示文摘The datasets of two Ocean Model Intercomparison Project(OMIP)simulation experiments from the LASG/IAP Climate Ocean Model,version 3(LICOM3),forced by two different sets of atmospheric surface data,are described in this paper.The experiment forced by CORE-II(Co-ordinated Ocean–Ice Reference Experiments,Phase II)data(1948–2009)is called OMIP1,and that forced by JRA55-do(surface dataset for driving ocean–sea-ice models based on Japanese 55-year atmospheric reanalysis)data(1958–2018)is called OMIP2.First,the improvement of LICOM from CMIP5 to CMIP6 and the configurations of the two experiments are described.Second,the basic performances of the two experiments are validated using the climatological-mean and interannual time scales from observation.We find that the mean states,interannual variabilities,and long-term linear trends can be reproduced well by the two experiments.The differences between the two datasets are also discussed.Finally,the usage of these data is described.These datasets are helpful toward understanding the origin system bias of the fully coupled model. | Pengfei LIN Zhipeng YU Hailong LIU Yongqiang YU Yiwen LI Jirong JIANG Wei XUE Kangjun CHEN Qian YANG Bowen ZHAO Jilin WEI Mengrong DING Zhikuo SUN Yaqi WANG Yao MENG Weipeng ZHENG Jinfeng MA | 2020 | Advances in Atmospheric Sciences2020，37，3： | 9 |
| 6 | Bile acids evoke placental inflammation by activating Gpbar1/NF-κB pathway in intrahepatic cholestasis of pregnancy显示文摘Intrahepatic cholestasis of pregnancy(ICP)is a cholestatic disorder with potentially deleterious consequences for fetuses.Although a clear correlation between the elevated levels of maternal serum bile acids and deficient fetal outcome has been established in clinical practice,the underlying mechanisms remain elusive.Herein,we report that bile acids induce NF-κB pathway activation via G protein-coupled bile acid receptor 1(Gpbar1),with consequent upregulation of inflammatory genes in trophoblasts,leading to aberrant leukocyte infiltration and inflammation in placenta.Ursodeoxycholic acid(UDCA),a drug used clinically to treat ICP,competes with other bile acids for binding with Gpbar1 and thus inhibits bile acid-induced inflammatory response in trophoblasts and improves fetal survival in pregnant rats with obstructive cholestasis.Notably,inhibition of NF-κB by andrographolide is more effective than UDCA in benefiting placentas and fetuses.Thus,anti-inflammation therapy targeting Gpbar1/NF-κB pathway could be effective in suppressing bile acid-induced inflammation and alleviating ICP-associated fetal disorders. | YouHua Zhang YouDong Pan ChangDong Lin YaJuan Zheng Hao Sun HaiLong Zhang JunLei Wang MengYa Yuan Tao Duan QiaoLing Du JianFeng Chen | 2016 | Journal of Molecular Cell Biology2016，8，6： | 8 |
| 7 | Meso-scale eddy in the South China Sea simulated by an eddy-resolving ocean model显示文摘Mesoscale eddies(MEs) in the South China Sea(SCS) simulated by a quasi-global eddy-resolving ocean general circulation model are evaluated against satellite data during 1993–2007. The modeled ocean data show more activity than shown by the satellite data and reproduces more eddies in the SCS. A total of 345(428) cyclonic eddies(CEs) and 330(371) anti-cyclonic eddies(AEs) generated for satellite(model) data are identified during the study period, showing increase of ~24% and ~12% for the model data, respectively. Compared with eddies in satellite, the simulated eddies tend to have smaller radii, larger amplitudes, a slightly longer lifetime, faster movement and rotation speed, a slightly larger nonlinear properties(U/c) in the model. However, the spatial distribution of generated eddies appears to be inhomogeneous, with more CEs in the northern part of SCS and fewer AEs in the southern part. This is attributed to the exaggerated Kuroshio intrusion in the model because the small islands in the Luzon Strait are still not well resolved although the horizontal resolution reaches(1/10)°. The seasonal variability in the number and the amplitude of eddies generated is also investigated. | FENG Baoxin LIU Hailong LIN Pengfei WANG Qi | 2017 | Acta Oceanologica Sinica2017，36，5： | 8 |
| 8 | The validation of the significant wave height product of HY-2altimeter–primary results显示文摘The HY-2 satellite was successfully launched on 16 August 2011.The HY-2 significant wave height(SWH)is validated by the data from the South China Sea(SCS)field experiment,National Data Buoy Center(NDBC)buoys and Jason-1/2 altimeters,and is corrected using a linear regression with in-situ measurements.Compared with NDBC SWH,the HY-2 SWH show a RMS of 0.36 m,which is similar to Jason-1 and Jason-2 SWH with the RMS of 0.35 m and 0.37 m respectively;the RMS of corrected HY-2 SWH is 0.27 m,similar to 0.27 m and 0.23 m of corrected Jason-1 and Jason-2 SWH.Therefore the accuracy of HY-2 SWH products is close to that of Jason-1/2 SWH,and the linear regression function derived can improve the accuracy of HY-2 SWH products. | CHEN Chuntao ZHU Jianhua LIN Mingsen ZHAO Yili HUANG Xiaoqi WANG He ZHANG Youguang PENG Hailong | 2013 | Acta Oceanologica Sinica2013，32，11： | 7 |
| 9 | Formulation of a new ocean salinity boundary condition and impact on the simulated climate of an oceanic general circulation model显示文摘The salinity boundary condition at the ocean surface plays an important role in the stability of long-term integrations of an oceanic general circulation model(OGCM) and in determining its equilibrium solutions.This study presents a new formulation of the salt flux calculation at the ocean surface based on physical processes of salt exchange at the air-sea interface.The formulation improves the commonly used virtual salt flux with constant reference salinity by allowing for spatial correlations between surface freshwater flux and sea-surface salinity while preserving the conservation of global salinity.The new boundary condition is implemented in the latest version of the National Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics/Institute of Atmospheric Physics Climate Ocean Model version 2(LICOM2.0).The impact of the new boundary condition on the equilibrium simulations of the model is presented.It is shown that the new formulation leads to a stronger Atlantic meridional overturning circulation(AMOC) that is closer to observational estimates.It also slightly improves poleward heat transport by the oceans in both the Atlantic and the global oceans. | JIN JiangBo ZENG QingCun WU Lin LIU HaiLong ZHANG MingHua | 2017 | Science China Earth Sciences2017，60，3： | 7 |
| 10 | A Quantitative Evaluation of Shale Gas Content in Different Occurrence States of the Longmaxi Formation: A New Insight from Well JY-A in the Fuling Shale Gas Field,Sichuan Basin显示文摘Comprehensive quantitative evaluation of shale gas content and the controlling factors in different occurrence states is of great significance for accurately assessing gas-bearing capacity and providing effective well-production strategies. A total of 122 core samples from well JY-A in the Fuling shale gas field were studied to reveal the characteristics of S_1 l shale,15 of which were selected to further predict the shale gas content in different occurrence states, which are dependent on geological factors in the thermal evolution process. Geological parameters were researched by a number of laboratory programs, and the factors influential in controlling shale gas content were extracted by both PCA and GRA methods and prediction models were confirmed by the BE method using SPSS software. Results reveal that the adsorbed gas content is mainly controlled by TOC, Ro, SSA, PD and pyrite content, and the free gas content is mainly controlled by S_2, quartz content, gas saturation and formation pressure for S_1 l in well JY-A. Three methods, including the on-site gas desorption method, the empirical formula method, and the multiple regression analysis method were used in combination to evaluate the shale gas capacity of well JY-A, all of which show that the overall shale gas content of well JY-A is in the range of 2.0–5.0 m^3/t and that the free gas ratio is about 50%, lower than that of well JY-1. Cause analysis further confirms the tectonics and preservation conditions of S_1 l in the geological processes, especially the influence of eastern boundary faults on well JY-A, as the fundamental reasons for the differences in shale gas enrichment in the Jiaoshiba area. | TANG Ling SONG Yan LI Qianwen PANG Xiongqi JIANG Zhenxue LI Zhuo TANG Xianglu YU Hailong SUN Yue FAN Shichao ZHU Lin | 2019 | Acta Geologica Sinica(English Edition)2019，93，2： | 7 |
| 11 | The FGOALS climate system model as a modeling tool for supporting climate sciences:An overview显示文摘Climate system models are useful tools for understanding the interactions among the components of the climate system and predicting/projecting future climate change. The development of climate models has been a central focus of the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of Atmospheric Physics, Chinese Academy of Sciences(LASG/IAP) since the establishment of the laboratory in 1985. In China, many pioneering component models and fully coupled models of the climate system have been developed by LASG/IAP. The fully coupled climate system developed in the recent decade is named FGOALS(Flexible Global Ocean-Atmosphere-Land System Model). In this paper, an application-oriented review of the LASG/IAP FGOALS model is presented. The improved model performances are demonstrated in the context of cloud-radiation processes, Asian monsoon, ENSO phenomena, Atlantic Meridional Overturning Circulation(AMOC) and sea ice. The FGOALS model has contributed to both CMIP5(Coupled Model Intercomparison Project-phase 5) and IPCC(Intergovernmental Panel on Climate Change) AR5(the Fifth Assessment Report). The release of FGOALS data has supported the publication of nearly 500 papers around the world. The results of FGOALS are cited ~106 times in the IPCC WG1(Working Group 1) AR5. In addition to the traditional long-term simulations and projections, near-term decadal climate prediction is a new set of CMIP experiment, progress of LAGS/IAP in the development of nearterm decadal prediction system is reviewed. The FGOALS model has supported many Chinese national-level research projects and contributed to the national climate change assessment report. The crucial role of FGOALS as a modeling tool for supporting climate sciences is highlighted by demonstrating the model's performances in the simulation of the evolution of Earth's climate from the past to the future. | TianJun Zhou Bin Wang YongQiang Yu YiMin Liu WeiPeng Zheng LiJuan Li Bo Wu PengFei Lin Zhun Guo WenMin Man Qing Bao AnMin Duan HaiLong Liu XiaoLong Chen Bian He JianDong Li LiWei Zou XiaoCong Wang LiXia Zhang Yong Sun WenXia Zhang | 2018 | Earth and Planetary Physics2018，2，4： | 6 |
| 12 | Two regimes of Atlantic multidecadal oscillation: cross-basin dependent or Atlantic-intrinsic显示文摘The Atlantic Multidedal Oscillation(AMO) is a prominent mode of sea surface temperature variability in the Atlantic and incurs significant global influence. Most coupled models failed to reproduce the observed 50–80-year AMO, but were overwhelmed by a 10–30-year AMO. Here we show that the 50–80-year AMO and 10–30-year AMO represent two different AMO regimes. The key differences are:(1) the 50–80-year AMO involves transport of warm and saline Atlantic water into the Greenland-Iceland-Norwegian(GIN)Seas prior to reaching its maximum positive phase, while such a transport is weak for the 10–30-year AMO;(2) the zonality of atmospheric variability associated with the 50–80 year AMO favors the transport of warm and saline water into the GIN Seas;(3) the disappearance of Pacific variability weakens the zonality of atmospheric variability and the transport of warm and saline water into the GIN Seas, leading to the weakening of the 50–80-year AMO. In contrast, the 10–30-year AMO does not show dependence on the variability in Pacific and in the GIN Seas and may be an Atlantic-intrinsic mode. Our results suggest that differentiating these AMO regimes and a better understanding of the cross-basin connections are essential to reconcile the current debate on the nature of AMO and hence to its reliable prediction, which is still lacking in most of coupled models. | Pengfei Lin Zipeng Yu Jianhua Lü Mengrong Ding Aixue Hu Hailong Liu | 2019 | Science Bulletin2019，64，3： | 6 |
| 13 | Removal of PCDD/Fs and PCBs from flue gas using a pilot gas cleaning system显示文摘A 100 Nm3 /hr capacity pilot scale dual bag filter (DBF) system was tested on the flue gas from an actual hazardous waste incinerator (HWI), the removal efficiency of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) was also studied. The first filter collected most of the fly ash and associated chlorinated organic; then activated carbon (AC) was injected and used to collect phase chlorinated organic from the gas. Concentrations of PCDD/Fs and PCBs after the DBF system were 0.07 and 0.01 ng TEQ/Nm3 , respectively, which were both far below the national emission standard. Comparing with the original single bag filter system, the PCDD/Fs concentration dropped a lot from 0.36 to 0.07 ng TEQ/Nm3 . Increasing AC feeding rate enhanced their collection efficiency, yet reduced the AC utilization efficiency, and it still needs further study to select an appropriate feeding rate in the system. These results will be useful for industrial application and assist in controlling emissions of PCDD/Fs and other persistent organic pollutions from stationary sources in China. | Xiaoqing Lin Yuqi Jin Hailong Wu Tong Chen Xiaodong Li Shengyong Lu Xuguang Jiang Jianhua Yan | 2013 | Journal of Environmental Sciences2013，25，9： | 5 |
| 14 | A Study on the Effects of the Surrounding Faults on Water Loss in the Zoige Wetland,China显示文摘The Zoige wetland is the biggest alpine wetland in the world,and an important water resource of the Yellow River.Due to natural and human factors,the Zoige wetland has been seriously degraded.Existing studies on the Zoige wetland mainly focus on the macro features of the wetland,while the influence of the surrounding faults on the Zoige wetland degradation is rarely studied.This study uses terrain data to analyze the cover change and the water loss caused by the Wqie-Seji fault based on the distributed hydrological model.The simulated water loss demonstrates that the Normalized Difference Vegetation Index(NDVI) is the most important factor for inducing water loss.The fault is also a factor that cannot be neglected,which has caused 33% of the wetland water loss.Therefore,it is of importance to study the influence of the fault on the wetland degradation. | LI Mei XU Rui HUANG Wendian SUN Hailong LUO Lin | 2011 | Journal of Mountain Science2011，8，4： | 5 |
| 15 | Assessment of the initial sea surface temperature product of the scanning microwave radiometer aboard on HY-2 satellite显示文摘HY-2 satellite is the first satellite for dynamic environmental parameters measurement of China,which was launched on 16th August 2011.A scanning microwave radiometer(RM)is carried for sea surface temperature(SST),sea surface wind speed,columnar water vapor and columnar cloud liquid water detection.In this paper,the initial SST product of RM was validated with in-situ data of National Data of Buoy Center(NDBC)mooring and Argo buoy.The validation results indicate the accuracy of RM SST is better than 1.7 C.The comparison of RM SST and WindSat SST shows the former is warmer than the latter at high sea surface wind speed and the difference between these SSTs is depend on the sea surface wind speed.Then,the relationship between the errors of RM SST and sea surface wind speed was analyzed using NDBC mooring measurements.Based on the results of assessment and errors analysis,the suggestions of taking account of the affection of sea surface wind speed and using sea surface wind speed and direction derived from the microwave scatteromter aboard on HY-2 for SST product calibration were given for retrieval algorithm improvement. | ZHAO Yili ZHU Jianhua LIN Mingsen CHEN Chuntao HUANG Xiaoqi WANG He ZHANG Youguang PENG Hailong | 2014 | Acta Oceanologica Sinica2014，33，1： | 5 |
| 16 | A Double-Index Method to Classify Kuroshio Intrusion Paths in the Luzon Strait显示文摘A double index(DI), which is made up of two sub-indices, is proposed to describe the spatial patterns of the Kuroshio intrusion and mesoscale eddies west to the Luzon Strait, based on satellite altimeter data. The area-integrated negative and positive geostrophic vorticities are defined as the Kuroshio warm eddy index(KWI) and the Kuroshio cold eddy index(KCI),respectively. Three typical spatial patterns are identified by the DI: the Kuroshio warm eddy path(KWEP), the Kuroshio cold eddy path(KCEP), and the leaking path. The primary features of the DI and three patterns are further investigated and compared with previous indices. The effects of the integrated area and the algorithm of the integration are investigated in detail. In general, the DI can overcome the problem of previously used indices in which the positive and negative geostrophic vorticities cancel each other out. Thus, the proportions of missing and misjudged events are greatly reduced using the DI.The DI, as compared with previously used indices, can better distinguish the paths of the Kuroshio intrusion and can be used for further research. | Zhida HUANG Hailong LIU Jianyu HU Pengfei LIN | 2016 | Advances in Atmospheric Sciences2016，33，6： | 5 |
| 17 | A preliminary assessment of the sea surface wind speed production of HY-2 scanning microwave radiometer显示文摘A scanning microwave radiometer(RM)was launched on August 16,2011,on board HY-2 satellite.The six-month long global sea surface wind speeds observed by the HY-2 scanning microwave radiometer are preliminarily validated using in-situ measurements and WindSat observations,respectively,from January to June 2012.The wind speed root-mean-square(RMS)difference of the comparisons with in-situ data is1.89 m/s for the measurements of NDBC and 1.72 m/s for the recent four-month data measured by PY30-1oil platform,respectively.On a global scale,the wind speeds of HY-2 RM are compared with the sea surface wind speeds derived from WindSat,the RMS difference of 1.85 m/s for HY-2 RM collocated observations data set is calculated in the same period as above.With analyzing the global map of a mean difference between HY-2 RM and WindSat,it appears that the bias of the sea surface wind speed is obviously higher in the inshore regions.In the open sea,there is a relatively higher positive bias in the mid-latitude regions due to the overestimation of wind speed observations,while the wind speeds are underestimated in the Southern Ocean by HY-2 RM relative to WindSat observations. | HUANG Xiaoqi ZHU Jianhua LIN Mingsen ZHAO Yili WANG He CHEN Chuntao PENG Hailong ZHANG Youguang | 2014 | Acta Oceanologica Sinica2014，33，1： | 4 |
| 18 | Enhanced piezo-response in copper halide perovskites based PVDF composite films显示文摘In-situ fabricated perovskite nanocrystals in polymeric matrix provide new generation composite materials for plenty of cutting edge technology. In this work, we report the in-situ fabrication of copper halide perovskite(MA_2CuCl_4, MA:CH_3NH_3^+) embedded poly(vinylidene fluoride)(PVDF) composite films. The optimized MA_2CuCl_4/PVDF composite films exhibit greatly enhanced piezo-response in comparasion with pure PVDF films. The enhancements were invesitgated and explained by applying piezo-response force microscopy(PFM) measurements and density functional theory(DFT) caculations. We proposed that the high piezoelectric properties of MA_2CuCl_4/PVDF composite films could be related to the large Cu off-centering displacement, the strong interactions between MA_2CuCl_4 and PVDF as well as large stress concentration around the MA_2CuCl_4 particles in the films. These piezoelectric composite films are expected to be suitable functional materials for flexible and/or wearable piezoelectrics. | Sheng Huang Gang Tang Hailong Huang Xian-gang Wu Puming Zhou Lin Zou Lei Xie Jianming Deng Xueyun Wang Haizheng Zhong Jiawang Hong | 2018 | Science Bulletin2018，63，19： | 4 |
| 19 | Effects of Kuroshio intrusion optimization on the simulation of mesoscale eddies in the northern South China Sea显示文摘The impacts of Kuroshio intrusion(KI) optimization on the simulation of meso-scale eddies(MEs) in the northern South China Sea(SCS) were investigated based on an eddy-resolving ocean general circulation model by comparing two numerical experiments with differences in their form and intensity of KI due to the optimizing topography at Luzon Strait(LS). We found that a reduced KI reduces ME activities in the northern SCS, which is similar to the observations. In this case, the biases of the model related to simulating the eddy kinetic energy(EKE) west of the LS and along the northern slope are remarkably attenuated. The reduced EKE modeling bias is associated with both the reduced number of anti-cyclonic eddies(AEs) and the reduced amplitude of cyclonic eddies(CEs). The EKE budget analysis further suggests that the optimization of the KI will change the EKE by changing the horizontal velocity shear and the slope of the thermocline, which are related to barotropic and baroclinic instabilities, respectively. The former plays the key role in regulating the EKE in the northern SCS due to the changing of the KI. The EKE advection caused by the KI is also important for the EKE budget to the west of the LS. | Baoxin Feng Hailong Liu Pengfei Lin | 2020 | Acta Oceanologica Sinica2020，39，3： | 4 |
| 20 | Sensitivity of Atlantic Meridional Overturning Circulation to the Dynamical Framework in an Ocean General Circulation Model显示文摘The horizontal coordinate systems commonly used in most global ocean models are the spherical latitude–longitude grid and displaced poles, such as a tripolar grid. The effect of the horizontal coordinate system on Atlantic meridional overturning circulation(AMOC) is evaluated by using an OGCM(ocean general circulation model). Two experiments are conducted with the model—one using a latitude–longitude grid(referred to as Lat_1) and the other using a tripolar grid(referred to as Tri). The results show that Tri simulates a stronger North Atlantic deep water(NADW) than Lat_1, as more saline water masses enter the Greenland–Iceland–Norwegian(GIN) seas in Tri. The stronger NADW can be attributed to two factors. One is the removal of the zonal filter in Tri, which leads to an increasing of the zonal gradient of temperature and salinity, thus strengthening the north geostrophic flow. In turn, it decreases the positive subsurface temperature and salinity biases in the subtropical regions. The other may be associated with topography at the North Pole, because realistic topography is applied in the tripolar grid while the latitude–longitude grid employs an artificial island around the North Pole. In order to evaluate the effect of the filter on AMOC, three enhanced filter experiments are carried out. Compared to Lat_1, an enhanced filter can also augment NADW formation, since more saline water is suppressed in the GIN seas, but accumulated in the Labrador Sea,especially in experiment Lat_2_S, which is the experiment with an enhanced filter on salinity. | Xiaolan LI Yongqiang YU Hailong LIU Pengfei LIN | 2017 | Journal of Meteorological Research2017，31，3： | 4 |
