1A Review of Seasonal Climate Prediction Research in China显示文摘The ultimate goal of climate research is to produce climate predictions on various time scales. In China, efforts to predict the climate started in the 1930 s. Experimental operational climate forecasts have been performed since the late 1950 s,based on historical analog circulation patterns. However, due to the inherent complexity of climate variability, the forecasts produced at that time were fairly inaccurate. Only from the late 1980 s has seasonal climate prediction experienced substantial progress, when the Tropical Ocean and Global Atmosphere project of the World Climate Research program(WCRP) was launched. This paper, following a brief description of the history of seasonal climate prediction research, provides an overview of these studies in China. Processes and factors associated with the climate variability and predictability are discussed based on the literature published by Chinese scientists. These studies in China mirror aspects of the climate research effort made in other parts of the world over the past several decades, and are particularly associated with monsoon research in East Asia. As the climate warms, climate extremes, their frequency, and intensity are projected to change, with a large possibility that they will increase. Thus, seasonal climate prediction is even more important for China in order to effectively mitigate disasters produced by climate extremes, such as frequent floods, droughts, and the heavy frozen rain events of South China.WANG Huijun FAN Ke SUN Jianqi LI Shuanglin LIN Zhaohui ZHOU Guangqing CHEN Lijuan LANG Xianmei LI Fang ZHU Yali CHEN Hong ZHENG Fei 2015Advances in Atmospheric Sciences2015,32,2:20
2Boron neutron capture therapy for malignant melanoma: first clinical case report in China显示文摘A phase Ⅰ/Ⅱ clinical trial for treating malignant melanoma by boron neutron capture therapy(BNCT) was designed to evaluate whether the world's first in-hospital neutron irradiator(IHNI) was qualified for BNCT. In this clinical trial planning to enroll 30 patients, the first case was treated on August 19, 2014. We present the protocol of this clinical trial, the treating procedure, and the clinical outcome of this first case. Only grade 2 acute radiation injury was observed during the first four weeks after BNCT and the injury healed after treatment. No late radiation injury was found during the 24-month follow-up. Based on positron emission tomography-computed tomography(PET/CT) scan, pathological analysis and gross examination, the patient showed a complete response to BNCT,indicating that BNCT is a potent therapy against malignant melanoma and IHNI has the potential to enable the delivery of BNCT in hospitals.Zhong Yong Zewen Song Yongmao Zhou Tong Liu Zizhu Zhang Yanzhong Zhao Yang Chen Congjun Jin Xiang Chen Jianyun Lu Rui Han Pengzhou Li Xulong Sun Guohui Wang Guangqing Shi Shaihong Zhu 2016Chinese Journal of Cancer Research2016,28,6:13
3Preliminary results of a regional air-sea coupled model over East Asia显示文摘We have established a regional air-sea coupled model over East Asia and conducted a 20-year integration to evaluate its performance in reproducing the present climate.The coupled model consists of RegCM3 and HYCOM controlled by the OASIS3 coupler with resuolution of 60 km for the atmosphere and 33 km for the ocean,respectively.Unlike some other regional air-sea coupled models,a one-way nesting method is employed in the oceanic component and a heat flux adjustment for solar radiation is used to remove an about 2°C cold bias in SST.The primary analysis for this 20-year integration shows that the coupled model successfully reproduces the main features of the circulations over East Asia,both in the atmosphere and the ocean,including climatology,seasonal and interannual variations.Improvements are seen in the coupled model compared to the uncoupled one,especially in the simulation of precipitation,the most important element of the East Asian monsoon,although there are still obvious discrepancies that come mainly from the model components themselves.Further analyses show that the rainfall simulation benefits from the enhancements of the Northwest Pacific Subtropical High in summer,which leads to the improvement of the moisture flux simula-tion at the middle-lower atmospheric circulation.The results indicate that the regional air-sea coupled model is more suitable for the East Asia monsoon simulation.LI Tao ZHOU GuangQing 2010Chinese Science Bulletin2010,55,21:10
4SST data assimilation experiments using an adaptive variational method显示文摘An adaptive variational data assimilation method is proposed by Zhu and Kamachi[1]. This method can adaptively adjust the model state without knowing explicitly the model error covariance matrix. The method enables very flexible ways to form some reduced order problems. A proper reduced order problem not only reduces computational burden but also leads to corrections that are more consistent with the model dynamics that trends to produce better forecast. These features make the adaptive variational method a good candidate for SST data assimilation because the model error of an ocean model is usually difficult to estimate. We applied this method to an SST data assimilation problem using the LOTUS data sets and an ocean mixed layer model (Mellor-Yamada level 2.5). Results of assimilation experiments showed good skill of improvement subsurface temperatures by assimilating surface observation alone.ZHU Jiang WANG Hui ZHOU Guangqing 2002Chinese Science Bulletin2002,47,23:7
5The El Ni?o-Southern Oscillation cycle simulated by the climate system model of Chinese Academy of Sciences显示文摘On the basis of more than 200-year control run, the performance of the climate system model of Chinese Academy of Sciences(CAS-ESM-C) in simulating the El Ni?o-Southern Oscillation(ENSO) cycle is evaluated, including the onset, development and decay of the ENSO. It is shown that, the model can reasonably simulate the annual cycle and interannual variability of sea surface temperature(SST) in the tropical Pacific, as well as the seasonal phase-locking of the ENSO. The model also captures two prerequisites for the El Ni?o onset, i.e., a westerly anomaly and a warm SST anomaly in the equatorial western Pacific. Owing to too strong forcing from an extratropical meridional wind, however, the westerly anomaly in this region is largely overestimated. Moreover, the simulated thermocline is much shallower with a weaker slope. As a result, the warm SST anomaly from the western Pacific propagates eastward more quickly, leading to a faster development of an El Ni?o. During the decay stage, owing to a stronger El Ni?o in the model, the secondary Gill-type response of the tropical atmosphere to the eastern Pacific warming is much stronger, thereby resulting in a persistent easterly anomaly in the western Pacific. Meanwhile, a cold anomaly in the warm pool appears as a result of a lifted thermocline via Ekman pumping. Finally, an El Ni?o decays into a La Ni?a through their interactions. In addition, the shorter period and larger amplitude of the ENSO in the model can be attributed to a shallower thermocline in the equatorial Pacific, which speeds up the zonal redistribution of a heat content in the upper ocean.SU Tonghua XUE Feng SUN Hongchuan ZHOU Guangqing 2015Acta Oceanologica Sinica2015,34,1:6

8A sea temperature data assimilation system for the China Seas and adjacent areas显示文摘A sea temperature data assimilation system forthe China Seas and adjacent areas is developed based on anested regional ocean circulation model and variational op-timal interpolation assimilation method. A 12-year assimila-tion experiment is performed by using the observationaltemperature profiles from World Ocean Database 1998(WOD98) and ECMWF reanalysis surface wind stress. Ex-perimental results indicate that the variational schemeshows good skill in assimilating the observed sea temperatureinto a regional ocean circulation model. Compared withsimulation alone, the sea temperature data assimilation sig-nificantly improves the performance of a regional oceanmodel and obtains comprehensive description of the circula-tions in the China Seas and adjacent areas. Assimilation re-sults, such as the strength and flowing axis of the Kuroshio,Yellow Sea Cold Water Mass and its corresponding horizon-tal circulation in summer and dipole eddies in the SouthChina Sea in the late summer/early autumn and the east-ward jet between them, are well consistent with the observedevidences.YOU Xiaobao, ZHOU Guangqing, ZHU Jiang LI Rongfeng LASG, Institutel of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China 2003Chinese Science Bulletin2003,48,S2:3
9Reduction of wastewater toxicity and change of microbial community in a hydrolysis acidification reactor pre-treating trimethylolpropane wastewater显示文摘Trimethylolpropane (TMP)wastewater is one of the most toxic petrochemical wastewater.Toxicants with high concentrations in TMP wastewater often inhibit the activity of microorganisms associated with biological treatment processes.The hydrolysis acidification process (HAP)is widely used to pretreat petrochemical wastewater.However,the effects of HAP on the reduction of wastewater toxicity and the relevant underlying mechanisms have rarely been reported.In this study,an HAP reactor was operated for 240 days.fed with actual TMP wastewater diluted by tap water in varying ratios.The toxicity of TMP wastewater was assessed with the inhibition ratio of oxygen uptake rate.When the organic loading rates were lower than 7.5kg COD/m^3/d,the toxicity of TMP wastewater was completely elminated.When the actual TMP wastewater was directly fed into the reactor,the toxicity of TMP wastewater decreased from 100%to 34.9%.According to the results of gas chromatography-mass spectrometry analysis,four main toxicants contained in TMP wastewater,namely,formaldehyde, 2-ethylacrolein.TMP and 2-ethylhexanol.were all significantly removed,with removal efficiencies of 93.42%,95.42%,72.85%and 98.94%,respectively.Compared with the removal efficiency of CODcr, the reduction rate of toxicity is markedly higher by HAP.In addition,the change of microbial community in the HAP reactor,along the operation period,was studied.The results revealed that, compared with the seed sludge.Firmicutes became the dominant phylum (abundance increased from 0.51% to 57.08%),followed by Proteobacteria and Bacteroidetes (abundance increased from 59.75% to 25.99%and from 4.70%to 8.39%,respectively).Xin Xing Yin Yu Hongbo Xi Guangqing Song Yajiao Wang Jiane Zuo Yuexi Zhou 2018Frontiers of Environmental Science & Engineering2018,12,6:2

13Risk factors and a prediction model for sepsis: A multicenter retrospective study in China显示文摘Background:Sepsis is typically associated with poor outcomes.There are various risk factors and predictive mod-els for sepsis based on clinical indicators.However,these models are usually predictive of all critical patients.This study explored the risk factors for 28-day outcomes of patients with sepsis and developed a prognosis prediction model.Methods:This was a multicenter retrospective analysis of sepsis patients hospitalized in three intensive care units(ICUs)from September 1st 2015,to June 30th 2020.Demographic,clinical history,and laboratory test data were extracted from patient records.Investigators explored the risk factors affecting 28-day sepsis prognosis by univariate analysis.The effects of confounding factors were excluded by multivariate logistic regression analysis,and new joint predictive factors were calculated.A model predicting 28-day sepsis prognosis was constructed through data processing analysis.Results:A total of 545 patients with sepsis were included.The 28-day mortality rate was 32.3%.Risk factors including age,D-dimer,albumin,creatinine,and prothrombin time(PT)were predictive of death from sepsis.The goodness-of-fit value for this prediction model was 0.534,and the area under the receiver operating characteristic curve was 0.7207.Further analysis of the immune subgroups(n=140)revealed a significant decrease in CD3+,CD4+CD8-,and CD4+CD29+memory effector T lymphocytes and an increase in CD56+natural killer(NK)cells in the hypoalbuminemia group compared with the normal albumin group(65.5 vs.58.3,P=0.005;41.2 vs.32.4,P=0.005;21.8 vs.17.1,P=0.029;12.6 vs.17.6,P=0.004).Conclusions:Risk factors for 28-day sepsis mortality include age,D-dimer,creatinine,PT,and albumin.A decrease in albumin level may exacerbate immunosuppression in patients with sepsis.This study establishes a prediction model based on these indicators,which shows a good degree of calibration and differentiation.This model may provide good predictive value for clinical sepsis prognosis.Ming Li Peijie Huang Weiwei Xu Zhigang Zhou Yun Xie Cheng Chen Yihan Jiang Guangqing Cui Qi Zhao Ruilan Wang 2022Journal of Intensive Medicine2022,2,3:1

15Pijx confers broad-spectrum seedling and panicle blast resistance by promoting the degradation of ATP β subunit and OsRbohC-mediated ROS burst in rice显示文摘Rice blast,caused by the fungal pathogen Magnaporthe oryzae,is one of the most important diseases of rice.Utilization of blast-resistance genes is the most economical,effective,and environmentally friendly way to control the disease.However,genetic resources with broad-spectrum resistance(BSR)that is effective throughout the rice growth period are rare.In this work,using a genome-wide association study,we identify a new blast-resistance gene,Pijx,which encodes a typical CC-NBS-LRR protein.Pijx is derived from a wild rice species and confers BSR to M.oryzae at both the seedling and panicle stages.The functions of the resistant haplotypes of Pijx are confirmed by gene knockout and overexpression experiments.Mechanistically,the LRR domain in Pijx interacts with and promotes the degradation of the ATP synthase β subunit(ATPb)via the 26S proteasome pathway.ATPb acts as a negative regulator of Pijx-mediated panicle blast resistance,and interacts with OsRbohC to promote its degradation.Consistently,loss of ATPb function causes an increase in NAPDH content and ROS burst.Remarkably,when Pijx is introgressed into two japonica rice varieties,the introgression lines show BSR and increased yields that are approximately 51.59%and 79.31%higher compared with those of their parents in a natural blast disease nursery.In addition,we generate PPL^(Pijx Pigm) and PPL^(Pijx Piz-t) pyramided lines and these lines also have higher BSR to panicle blast compared with Pigm-or Piz-t-containing rice plants.Collectively,this study demonstrates that Pijx not only confers BSR to M.oryzae but also maintains high and stable rice yield,providing new genetic resources and molecular targets for breeding rice varieties with broad-spectrum blast resistance.Ning Xiao Yunyu Wu Xiaoxiang Zhang Zeyun Hao Zichun Chen Zefeng Yang Yue Cai Ruyi Wang Ling Yu Zhiping Wang Yue Lu Wei Shi Cunhong Pan Yuhong Li Changhai Zhou Jianju Liu Niansheng Huang Guangqing Liu Hongjuan Ji Shuhao Zhu Shuai Fang Yuese Ning Aihong Li 2023Molecular Plant2023,16,11:0

17Effect of 2-butenal manufacture wastewater to methanogenic activity and microbial community显示文摘The synthesis of 2-butenal,which is a vital raw material for the production of sorbic acid as a food preservative,generates some toxic by-products,so it is urgent to seek better detoxification strategies for the treatment of 2-butenal manufacture wastewater.In this study,batch experiments were carried out to investigate the inhibition effect of wastewater on the methanogenic activity.To understand the wastewater toxicity to anaerobic granular sludge,variations of the specific methanogenic activity(SMA)and extracellular polymeric substance(EPS)constituents at various wastewater CODs were investigated.Ultraviolet-visible(UV-vis)spectra and Fourier transform infrared(FT-IR)spectra were employed to analyze the structure of the EPS.The results showed that the inhibitory ratio of 2-butenal manufacture wastewater was less than 8.4%on the anaerobic granular sludge when the CODs were less than 959 mg/L.However,the inhibitory ratio increased from 36.4%to 93.6% when CODs increased from 2396 mg/L to 9585 mg/L,with the SMA decreasing from 39.1 mL CH4/(gVSS·d)to 3.2 mL CH4/(gVSS·d).The diversity of the microbial community under various CODs was researched by Illumina 16S rRNA Miseq sequencing and the results demonstrated that Proteiniphilum、Petrimonas and Syntrophobacter were the dominant bacteria genera in all sample.Regarding archaea,Methanobacterium was the most dominated archaea genera,followed by the Methanosaeta group in all samples.Moreover,the bacterial communities had changed obviously with increasing CODs,which indicated high CODs played a negative impact on the richness and diversity of bacterial community in the sludge samples.Guangqing Song Hongbo Xi Xiumei Sun Yudong Song Yuexi Zhou 2018Frontiers of Environmental Science & Engineering2018,12,5:0
18CAS-ESM2.0 Model Datasets for the CMIP6 Flux-Anomaly-Forced Model Intercomparison Project (FAFMIP)显示文摘The second version of the Chinese Academy of Sciences Earth System Model(CAS-ESM2.0)is participating in the Flux-Anomaly-Forced Model Intercomparison Project(FAFMIP)experiments in phase 6 of the Coupled Model Intercomparison Project(CMIP6).The purpose of FAFMIP is to understand and reduce the uncertainty of ocean climate changes in response to increased CO2 forcing in atmosphere-ocean general circulation models(AOGCMs),including the simulations of ocean heat content(OHC)change,ocean circulation change,and sea level rise due to thermal expansion.FAFMIP experiments(including faf-heat,faf-stress,faf-water,faf-all,faf-passiveheat,faf-heat-NA50pct and faf-heat-NA0pct)have been conducted.All of the experiments were integrated over a 70-year period and the corresponding data have been uploaded to the Earth System Grid Federation data server for CMIP6 users to download.This paper describes the experimental design and model datasets and evaluates the preliminary results of CAS-ESM2.0 simulations of ocean climate changes in the FAFMIP experiments.The simulations of the changes in global ocean temperature,Atlantic Meridional Overturning Circulation(AMOC),OHC,and dynamic sea level(DSL),are all reasonably reproduced.Jiangbo JIN He ZHANG Xiao DONG Hailong LIU Minghua ZHANG Xin GAO Juanxiong HE Zhaoyang CHAI Qingcun ZENG Guangqing ZHOU Zhaohui LIN Yi YU Pengfei LIN Ruxu LIAN Yongqiang YU Mirong SONG Dongling ZHANG 2021Advances in Atmospheric Sciences2021,38,2:0
19CAS-ESM2.0 Model Datasets for the CMIP6 Ocean Model Intercomparison Project Phase 1 (OMIP1)显示文摘As a member of the Chinese modeling groups,the coupled ocean-ice component of the Chinese Academy of Sciences’Earth System Model,version 2.0(CAS-ESM2.0),is taking part in the Ocean Model Intercomparison Project Phase 1(OMIP1)experiment of phase 6 of the Coupled Model Intercomparison Project(CMIP6).The simulation was conducted,and monthly outputs have been published on the ESGF(Earth System Grid Federation)data server.In this paper,the experimental dataset is introduced,and the preliminary performances of the ocean model in simulating the global ocean temperature,salinity,sea surface temperature,sea surface salinity,sea surface height,sea ice,and Atlantic Meridional Overturning Circulation(AMOC)are evaluated.The results show that the model is at quasi-equilibrium during the integration of 372 years,and performances of the model are reasonable compared with observations.This dataset is ready to be downloaded and used by the community in related research,e.g.,multi-ocean-sea-ice model performance evaluation and interannual variation in oceans driven by prescribed atmospheric forcing.Xiao DONG Jiangbo JIN Hailong LIU He ZHANG Minghua ZHANG Pengfei LIN Qingcun ZENG Guangqing ZHOU Yongqiang YU Mirong SONG Zhaohui LIN Ruxu LIAN Xin GAO Juanxiong HE Dongling ZHANG Kangjun CHEN 2021Advances in Atmospheric Sciences2021,38,2:0
20Co-pyrolysis of soybean soapstock with iron slag/aluminum scrap,and characterization and analysis of their products显示文摘Soybean soapstock(SS) is one of the main solid wastes produced in the refinery of edible oil processing. In this study, the co-pyrolysis of SS with iron slag(IS) and aluminum scrap(AS) was carried out in a tubular furnace. The gas, liquid and solid products were characterized and the char yield decreased with increasing IS/AS ratio. IS and AS can improve the gas yield, and when the ratio of SS/IS was 1:0.25, the total pyrolysis gas and hydrogen contents were significantly increased. The content of oxygen compounds in pyrolysis oil decreased during co-pyrolysis, while AS promoted the content of polycyclic aromatic hydrocarbons in pyrolysis oil. The co-pyrolysis reaction can be divided into four stages, the mass loss rate reaches the maximum at the third stage(390–575 ℃). The molar ratio of H/C was lower for pyrolysis,indicating good stability of pyrolysis char owing to the high degree of carbonization and aromaticity.The possible co-pyrolysis reaction mechanism was explored.Xueguang Li Mengyan Yu Changfa Zhang Xiangtong Li Guangqing Liu Jianjun Dai Chunbao Zhou Yang Liu Jie Fu Yingwen Zhang Bang Yao 2023Chinese Journal of Chemical Engineering2023,53,1:0
