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
2The responses of East Asian Summer monsoon to the North Atlantic Meridional Overturning Circulation in an enhanced freshwater input simulation显示文摘We investigated the response of the East Asian Summer Monsoon (EASM) to a weakened Atlantic Meridional Overturning Circulation (AMOC) and its mechanism in an enhanced freshwater input experiment (FW) by using a fully-coupled climate model. The response was a weakened EASM and the mechanisms can be explained as follows. The simulated weakened AMOC resulted in a drop in sea surface temperature (SST) in the North Atlantic (NA) and, correspondingly, an anomalous high sea level pressure (SLP) over the North American regions, which in turn increased the northeast surface winds across the equator in the eastern tropical Pacific (ETP). The anomalous northeast winds then induced further upwelling in the ETP and stronger air/sea heat exchange, therefore leading to an anomalous cooling of the eastern tropical sea surface. As a result, the climatologic Hadley Circulation (HC) was weakened due to an anomalous stronger sinking of air in the ETP north of the equator, whereas the Walker Circulation (WC) in the western tropical Pacific (WTP) north of the equator was strengthened with an eastward-shifted upwelling branch. This feature was in agreement with the anomalous convergent winds in the WTP, and led to a weakened EASM and less East Asian summer precipitation (EASP). Furthermore, comparison with previous freshwater experiments indicates that the strength of EASP could be influenced by the magnitude of the added freshwater.YU Lei GAO YongQi WANG HuiJun GUO Dong LI ShuangLin 2009Chinese Science Bulletin2009,54,24:11
3Lead-Lag Connection of the Atlantic Multidecadal Oscillation (AMO) with East Asian Surface Air Temperatures in Instrumental Records显示文摘The authors analyzed the lead-lag connection of the Atlantic Multidecadal Oscillation (AMO) with East Asian surface air temperatures (EATs) using instrumental records, and compared the results with the Pacific Decadal Oscillation (PDO). The maximum correlation was found when EATs led the AMO by five to seven years (with a correlation coefficient of 0.72, whereas the correlation coefficient was 0.91 when the AMO led EATs by 24-28 years). This is different from the PDO, which mostly correlated with EATs when the PDO led EATs by 13-15 years (with a correlation coefficient of 0.67, whereas the correlation coefficient was 0.76 when EATs led the PDO by 24-26 years). The PDO led the AMO by 19-21 years (with a correlation coefficient of 0.71, whereas the correlation coefficient was 0.84 when the AMO led the PDO by 16-18 years). These results support a previous understanding that EATs positively correlate with the AMO, and imply that the observed East Asian warming trend may have been slowing down since the early 2010s.LI Shuanglin LUO Fei-Fei 2013Atmospheric and Oceanic Science Letters2013,6,3:10
4Projecting the Summer Climate of China's Mainland in the Middle 21st Century: Will the Droughts in North China Persist?显示文摘Since no consensus has been reached in previous studies about how the summer climate in China will evolve in the first half of the 21st century, this issue is addressed here through sensitivity experiments by forcing an atmospheric general circulation model (AGCM), the Geophysical Fluid Dynamics Laboratory (GFDL)'s Atmospheric Model Version 2.0 (AM2) with projected sea surface temperature (SST) trend. A total of two SST trends from the Intergovernmental Panels on Climate Change (IPCC) Special Report on Emissions Scenario (SRES) A1B are used. The two trends are from two coupled climate system models, the National Center for Atmospheric Research (NCAR) Community Climate System Model Version 3.0 (CCSM3) and the GFDL Climate Model Version 2.0 (CM2), respectively. Results consistently suggest a substantial warming and drying trend over much of China, with a surface air temperature increase of 1.0 2.0 ℃ and a 10% 20% decrease in rainfall. Exceptions are the areas from northwestern China to western North China as well as the southern Tibetan Plateau, which are projected to be wetter with a rainfall anomaly percentage increase of 10% 50%. The drying in eastern North China has not been documented to date but appears to be reasonable. Physically, it is attributed to anomalous northeasterly winds at the rear of a low-level cyclone over the South China Sea, the Philippines and the subtropical western North Pacific. These conditions, which govern the climate of eastern China, are forced by the northward shift of convection over warm waters due to additional warming.LI Shuanglin 2008Atmospheric and Oceanic Science Letters2008,1,1:8
5The influence of tropical Indian Ocean warming on the Southern Hemispheric stratospheric polar vortex显示文摘During the past decades, concurrent with global warming, most of global oceans, particularly the tropical Indian Ocean, have become warmer. Meanwhile, the Southern Hemispheric stratospheric polar vortex (SPV) exhibits a deepening trend. Although previous modeling studies reveal that radiative cooling effect of ozone depletion plays a dominant role in causing the deepening of SPV, the simulated ozone-depletion-induced SPV deepening is stronger than the observed. This suggests that there must be other factors canceling a fraction of the influence of the ozone depletion. Whether the tropical Indian Ocean warming (IOW) is such a factor is unclear. This issue is addressed by conducting ensemble atmospheric general circulation model (AGCM) experiments. And one idealized IOW with the amplitude as the observed is prescribed to force four AGCMs. The results show that the IOW tends to warm the southern polar stratosphere, and thus weakens SPV in austral spring to summer. Hence, it offsets a fraction of the effect of the ozone depletion. This implies that global warming will favor ozone recovery, since a warmer southern polar stratosphere is un-beneficial for the formation of polar stratospheric clouds (PSCs), which is a key factor to ozone depletion chemical reactions.LI ShuangLin Nansen-Zhu International Research Centre, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China 2009Science China Earth Sciences2009,52,3:7
6Asymmetric Relationship between the Meridional Displacement of the Asian Westerly Jet and the Silk Road Pattern显示文摘In previous work, a significant relationship was identified between the meridional displacement of the Asian westerly jet(JMD) and the Silk Road Pattern(SRP) in summer. The present study reveals that this relationship is robust in northward JMD years but absent in southward JMD years. In other words, the amplitude of the SRP increases with northward displacement of the jet but shows little change with southward displacement. Further analysis indicates that, in northward JMD years, the Rossby wave source(RWS) anomalies, which are primarily contributed by the planetary vortex stretching, are significantly stronger around the entrance of the Asian jet, i.e., the Mediterranean Sea–Caspian Sea area, with the spatial distribution being consistent with that related to the SRP. By contrast, in southward JMD years, the RWS anomalies are much weaker.Therefore, this study suggests that the RWS plays a crucial role in inducing the asymmetry of the JMD–SRP relationship.The results imply that climate anomalies may be stronger in strongly northward-displaced JMD years due to the concurrence of the JMD and SRP, and thus more attention should be paid to these years.Xiaowei HONG Riyu LU Shuanglin LI 2018Advances in Atmospheric Sciences2018,35,4:6
7A Comparison of the Effects of Interannual Arctic Sea Ice Loss and ENSO on Winter Haze Days: Observational Analyses and AGCM Simulations显示文摘This study compares the impacts of interannual Arctic sea ice loss and ENSO events on winter haze days in China's Mainland through observational analyses and AGCM sensitivity experiments. The results suggest that(1) Arctic sea ice loss favors an increase in haze days in central–eastern China;(2) the impact of ENSO is overall contained within southern China, with increased(reduced) haze days during La Ni?a(El Ni?o) winters; and(3) the impacts from sea ice loss and ENSO are linearly additive. Mechanistically, Arctic sea ice loss causes quasi-barotropic positive height anomalies over the region from northern Europe to the Ural Mountains(Urals in brief) and weak and negative height anomalies over the region from central Asia to northeastern Asia. The former favors intensified frequency of the blocking over the regions from northern Europe to the Urals, whereas the latter favors an even air pressure distribution over Siberia, Mongolia, and East Asia. This large-scale circulation pattern favors more frequent occurrence of calm and steady weather in northern China and, as a consequence, increased occurrence of haze days. In comparison,La Ni?a(El Ni?o) exerts its influence along a tropical pathway by inducing a cyclonic(anticyclonic) lower-tropospheric atmospheric circulation response over the subtropical northwestern Pacific. The northeasterly(southwesterly)anomaly at the northwestern rear of the cyclone(anticyclone) causes reduced(intensified) rainfall over southeastern China, which favors increased(reduced) occurrence of haze days through the rain-washing effect.Shuanglin LI Zhe HAN Huopo CHEN 2017Journal of Meteorological Research2017,31,5:6
8A New Approach for Classifying Two Types of El Nio Events显示文摘In recent decades, the typical El Nio events with the warmest SSTs in the tropical eastern Pacific have become less common, and a different of El Nio with the warmest SSTs in the central Pacific, which is flanked on the east and west by cooler SSTs, has become more fre-quent. The more recent type of El Nio was referred to as central Pacific El Nio, warm pool El Nio, or dateline El Nio, or the El Nio Modoki. Central Pacific El Nio links to a different tropical-to-extratropical teleconnection and exerts different impacts on climate, and several classification approaches have been proposed. In this study, a new classification approach is proposed, which is based on the linear combination (sum or difference) of the two leading Empirical Orthogonal Functions (EOFs) of tropical Pacific Ocean sea surface temperature anomaly (SSTA), and the typical El Ni o index (TENI) and the central El Nio index (CENI) are able to be derived by projecting the observed SSTA onto these combinations. This classification not only reflects the characteristics of non-orthogonality between the two types of events but also yields one period peaking at approximate two to seven years. In particular, this classification can distin-guish the different impacts of the two types of events on rainfall in the following summer in East China. The typical El Nio events tend to induce intensified rainfall in the Yangtze River valley, whereas the central Pacific El Nio tends to induce intensified rainfall in the Huaihe River valley. Thus, the present approach may be appropriate for studying the impact of different types of El Nio on the East Asian climate.LI Shuanglin WANG Qin 2012Atmospheric and Oceanic Science Letters2012,5,5:5
9The Influence of Regional SSTs on the Interdecadal Shift of the East Asian Summer Monsoon显示文摘自从 1970 年代末,东亚经历了重要 interdecadal 气候移动。这移动被全球 SST 的一个十的变化伴随。以前的研究建议了全球 SST 背景地位的十的移动在如此的气候的移动起了一个实质的作用。然而,不同地区性的 SST 的单个角色仍然保持不清楚。在这研究,我们用一个大气的一般发行量模型,的整体实验调查了这些角色 GFDL (地球物理的液体动力学实验室) AM2。二种整体被执行。第一是模型与观察 climatological SST 在被驾驶的一个控制整体。第二是模型在分开的海洋区域与观察 climatological SST 正 interdecadal SST 背景移动在被驾驶的一个试验性的整体。结果建议在热带的 SST 移动在 extratropics 比那些施加了更重要的影响,尽管后者平常地贡献移动。夏天 monsoonal 发行量系统的变化包括南方亚洲人高度,向西和平的副热带的高度,和降低水平的空气流动,被分析。结果证明与热带以外的 SST 导致的那些比较,热带 SST 导致的移动忍受更多的类似到观察并且到模拟,全球 SST 规定了。特别地,在热带太平洋的观察 SST 移动,而非印度洋,自从 1970 年代,显著地作出贡献到东方亚洲夏天季风的移动。FU Jianjian LI Shuanglin 2013Advances in Atmospheric Sciences2013,30,2:5
10The warmest year 2015 in the instrumental record and its comparison with year 1998显示文摘本文利用CRU、NASA和NOAA的近地面气温异常(SATA)数据,对比分析了2015年和1998年的温度异常分布特征,证实了2015年是有观测记录以来温度最暖的一年,并进一步利用EEMD方法探讨了不同时间尺度对2015年温度异常的贡献以及其温度最暖的形成原因。结果表明,年代际及其以上的时间尺度和长期增暖趋势对2015年年平均SATA贡献为0.64°C,远远大于与ENSO信号相关的年际时间尺度的贡献(为0.1°C),说明长时间尺度和全球长期变暖趋势对2015年温度异常的形成有重要贡献。ZHANG Chao LI Shuanglin WAN Jiang-Hua 2016Atmospheric and Oceanic Science Letters2016,9,6:5
11Performance of the Wind Farm Parameterization Scheme Coupled with the Weather Research and Forecasting Model under Multiple Resolution Regimes for Simulating an Onshore Wind Farm显示文摘We use the Wind Farm Parameterization(WFP) scheme coupled with the Weather Research and Forecasting model under multiple resolution regimes to simulate turbulent wake dynamics generated by a real onshore wind farm and their influence at the local meteorological scale. The model outputs are compared with earlier modeling and observation studies. It is found that higher vertical and horizontal resolutions have great impacts on the simulated wake flow dynamics. The corresponding wind speed deficit and turbulent kinetic energy results match well with previous studies. In addition, the effect of horizontal resolution on near-surface meteorology is significantly higher than that of vertical resolution. The wake flow field extends from the start of the wind farm to downstream within 10 km, where the wind speed deficit may exceed 4%. For a height of 150 m or at a distance of about 25 km downstream, the wind speed deficit is around 2%. This indicates that, at a distance of more than 25 km downstream, the impact of the wind turbines can be ignored. Analysis of near-surface meteorology indicates a night and early morning warming near the surface, and increase in near-surface water vapor mixing ratio with decreasing surface sensible and latent heat fluxes. During daytime, a slight cooling near the surface and decrease in the near-surface water vapor mixing ratio with increasing surface sensible and latent heat fluxes is noticed over the wind farm area.Rajabu J.MANGARA Zhenhai GUO Shuanglin LI 2019Advances in Atmospheric Sciences2019,36,2:5
12Joint statistical-dynamical approach to decadal prediction of East Asian surface air temperature显示文摘A joint statistical-dynamical method addressing both the internal decadal variability and effect of anthropogenic forcing was developed to predict the decadal components of East Asian surface air temperature(EATs)for three decades(2010–2040).As previous studies have revealed that the internal variability of EATs(EATs_int)is influenced mainly by the ocean,we first analyzed the lead-lag connections between EATs_int and three sea surface temperature(SST)multidecadal modes using instrumental records from 1901 to 1999.Based on the lead-lag connections,a multiple linear regression was constructed with the three SST modes as predictors.The hindcast for the years from 2000 to 2005 indicated the regression model had high skill in simulating the observational EATs_int.Therefore,the prediction for EATs_int(Re_EATs_int)was obtained by the regression model based on quasi-periods of the decadal oceanic modes.External forcing from greenhouse gases is likely associated with global warming.Using monthly global land surface air temperature from historical and projection simulations under the Representative Concentration Pathway(RCP)4.5 scenario of 19 Coupled General Circulation Models participating in the fifth phase of the Coupled Model Intercomparison Project(CMIP5),we predicted the curve of EATs(EATs_trend)relative to1970–1999 by a second-order fit.EATs_int and EATs_trend were combined to form the reconstructed EATs(Re_EATs).It was expected that a fluctuating evolution of Re_EATs would decrease slightly from 2015 to 2030 and increase gradually thereafter.Compared with the decadal prediction in CMIP5 models,Re_EATs was qualitatively in agreement with the predictions of most of the models and the multi-model ensemble mean,indicating that the joint statistical-dynamical approach for EAT is rational.LUO FeiFei LI ShuangLin 2014Science China Earth Sciences2014,57,12:5
13Tetrahedral Framework Nucleic Acid-Based Delivery of Resveratrol Alleviates Insulin Resistance:From Innate to Adaptive Immunity显示文摘Obesity-induced insulin resistance is the hallmark of metabolic syndrome,and chronic,low-grade tissue inflammation links obesity to insulin resistance through the activation of tissue-infiltrating immune cells.Current therapeutic approaches lack efficacy and immunomodulatory capacity.Thus,a new therapeutic approach is needed to prevent chronic inflammation and alleviate insulin resistance.Here,we synthesized a tetrahedral framework nucleic acid(tFNA)nanoparticle that carried resveratrol(RSV)to inhibit tissue inflammation and improve insulin sensitivity in obese mice.The prepared nanoparticles,namely tFNAs-RSV,possessed the characteristics of simple synthesis,stable properties,good water solubility,and superior biocompatibility.The tFNA-based delivery ameliorated the lability of RSV and enhanced its therapeutic efficacy.In high-fat diet(HFD)-fed mice,the administration of tFNAs-RSV ameliorated insulin resistance by alleviating inflammation status.tFNAs-RSV could reverse M1 phenotype macrophages in tissues to M2 phenotype macrophages.As for adaptive immunity,the prepared nanoparticles could repress the activation of Th1 and Th17 and promote Th2 and Treg,leading to the alleviation of insulin resistance.Furthermore,this study is the first to demonstrate that tFNAs,a nucleic acid material,possess immunomodulatory capacity.Collectively,our findings demonstrate that tFNAs-RSV alleviate insulin resistance and ameliorate inflammation in HFD mice,suggesting that nucleic acid materials or nucleic acid-based delivery systems may be a potential agent for the treatment of insulin resistance and obesity-related metabolic diseases.Yanjing Li Shaojingya Gao Sirong Shi Dexuan Xiao Shuanglin Peng Yang Gao Ying Zhu Yunfeng Lin 2021Nano-Micro Letters2021,13,6:4
14Impact of European Black Carbon on East Asian Summer Climate显示文摘The remote response of the East Asian summer monsoon(EASM)to European black carbon(EUBC)aerosols was studied by using an ensemble of sensitivity experiments with the Geophysical Fluid Dynamics Laboratory(GFDL)atmospheric general circulation model(AGCM)Atmospheric Model version 2.1(AM2.1).The results show that EUBC causes an enhanced EASM.The resulted enhanced southwesterly brings more moisture supply from the Bay of Bengal,which causes an increase in precipitation over the Yangtze River valley,northeastern China,the eastern part of the Yellow River valley,and the Tibetan Plateau.Diagnostic examination suggests that EUBC induces enhanced tropospheric heating over most of the Eurasian Continent through a propagating wave train and horizontal air temperature advection.This phenomenon results in intensified thermal contrast between land and ocean,which accounts for the enhanced EASM.Moreover,reductions in EUBC emission in 1992 may have contributed to decadal weakening of the EASM in the early 1990s.WAN Jiang-Hua Rashed MAHMOOD LI Shuanglin 2013Atmospheric and Oceanic Science Letters2013,6,5:4

16DNA Barcoding and Mini-DNA Barcoding Reveal Mislabeling of Salmonids in Different Distribution Channels in the Qingdao Area显示文摘There is an increasing demand for salmonid authentication due to the globalization of the salmonid trade.DNA barcoding and mini-DNA barcoding are widely used for identifying fish species based on a fragment of the mitochondrial cytochrome c oxidase subunit I(COI)sequence.In this study,rainbow trout(Oncorhynchus mykiss),steelhead trout(O.mykiss),and Atlantic salmon(Salmo salar)collected from two salmonid aquaculture bases in China were authenticated by DNA barcoding(about 650 bp)and mini-DNA barcoding(127 bp)to evaluate the accuracy of the two methods in the identification of different salmonid species.The results revealed that both methods could effectively distinguish O.mykiss and S.salar with 100%accuracy.However,the two methods failed to separate rainbow trout(O.mykiss)and steelhead trout(O.mykiss),which are the same species but cultured in different water environments.Moreover,salmonid samples from three main distribution channels in the Qingdao area(traditional supermarkets,online supermarkets,and sushi bars)were identified by the two methods.Substitution of S.salar with O.mykiss was discovered,and the 27.78%overall substitution rate of salmonids in the Qingdao area was higher than those in other regions reported in previous studies.In addition,the mislabeling rates of salmonids from traditional supermarkets,online supermarkets,and sushi bars were compared in this study.The mislabeling rate was significantly greater in sushi bars(50%)than in the other two channels(16.67%),suggesting that stronger monitoring and enforcement measures are necessary for the aquatic food catering industry.HAN Cui DONG Shuanglin LI Li GAO Qinfeng ZHOU Yangen 2021Journal of Ocean University of China2021,20,6:3
17Effect of the Morphology of ZnO Support on the Desulfurization and Regeneration Performance of Ni/ZnO Catalyst显示文摘The Ni/ZnO desulfurization catalyst has been highly valued for its high desulfurization rate and low octane value loss. However, during the process of desulfurization, ZnO is prone to deactivation and the active component Ni is susceptible to agglomeration, which can affect the performance of the catalyst. In order to solve these problems, the modification of ZnO support has been extensively studied. The granular, short rod-shaped and nanowire-structured ZnO were synthesized by controlling the concentration of NaOH, and the desulfurization catalyst was prepared with ZnO serving as the support after loading of metallic Ni. The catalyst was characterized by X-ray diffraction, N2 adsorption-desorption, SEM, TEM and other analytical methods. The desulfurization performance of the catalyst was investigated with n-heptane - thiophene used as model compounds. Test results showed that the morphology and size of ZnO support has great influence on the desulfurization performance of the catalyst. Desulfurization catalyst prepared with nanowire-structured ZnO support has the best desulfurization performance, with its desulfurization rate reaching 98.2%. The result was achieved mainly due to the nanowire structure of ZnO support which could effectively restrain the agglomeration of metallic Ni on the surface and reduce the particle size of the active component of metallic Ni so as to improve its dispersion on the surface of the support. In addition, the nanowire structure can reduce the diffusion resistance of thiophene in the reaction process and provide a channel conducive to sulfur transfer and diffusion, which makes it perform well in the desulphurization reaction process and regeneration process.Kang Lei Wang Haiyan Han Bing Li Shuanglin Sun Na Yang Zhanxu 2019China Petroleum Processing & Petrochemical Technology2019,21,2:3
18Air–Sea Coupling Enhances the East Asian Winter Climate Response to the Atlantic Multidecadal Oscillation显示文摘A simple air–sea coupled model,the atmospheric general circulation model(AGCM) of the National Centers for Environmental Prediction coupled to a mixed-layer slab ocean model,is employed to investigate the impact of air–sea coupling on the signals of the Atlantic Multidecadal Oscillation(AMO). A regional coupling strategy is applied,in which coupling is switched off in the extratropical North Atlantic Ocean but switched on in the open oceans elsewhere. The coupled model is forced with warm-phase AMO SST anomalies,and the modeled responses are compared with those from parallel uncoupled AGCM experiments with the same SST forcing. The results suggest that the regionally coupled responses not only resemble the AGCM simulation,but also have a stronger intensity. In comparison,the coupled responses bear greater similarity to the observational composite anomaly. Thus,air–sea coupling enhances the responses of the East Asian winter climate to the AMO. To determine the mechanism responsible for the coupling amplification,an additional set of AGCM experiments,forced with the AMO-induced tropical SST anomalies,is conducted. The SST anomalies are extracted from the simulated AMO-induced SST response in the regionally coupled model. The results suggest that the SST anomalies contribute to the coupling amplification. Thus,tropical air–sea coupling feedback tends to enhance the responses of the East Asian winter climate to the AMO.ZHOU Xiaomin LI Shuanglin LUO Feifei GAO Yongqi Tore FUREVIK 2015Advances in Atmospheric Sciences2015,32,12:3
19Simulated Influence of the Atlantic Multidecadal Oscillation on Summer Eurasian Nonuniform Warming since the Mid-1990s显示文摘Based on ensemble experiments with three atmospheric general circulation models(AGCMs), this study investigates the role of the Atlantic Multidecadal Oscillation(AMO) in shaping the summer nonuniform warming over the Eurasian continent since the mid-1990 s. The results validate that the positive-phase AMO can indeed cause nonuniform warming,with predominant amplified warming over Europe–West Asia and Northeast Asia, but with much weaker warming over Central Asia. The underlying mechanism is then diagnosed from the perspective that the boundary forcing modulates the intrinsic atmospheric variability. The results highlight the role of the Silk Road Pattern(SRP), an intrinsic teleconnection pattern across the subtropical Eurasian continent propagating along the Asian jet. The SRP can not only be identified from the AGCM control experiments with the climatological sea surface temperature(SST), but can also be simulated by the AMO-related SST anomaly(SSTA) forcing. Furthermore, diagnostic linear baroclinic model experiments are conducted, and the results suggest that the SRP can be triggered by the AMO-related tropical diabatic heating. The AMO-triggered SRP-like responses feature anticyclonic circulations over Europe–West Asia and Northeast Asia, but cyclonic circulation over Central Asia. These responses cause increased warm advection towards Europe–West Asia and Northeast Asia, reduced precipitation and cloud cover, and then increased downward shortwave radiation. This increased warm advection and increased downward shortwave radiation together cause amplified warming in Europe–West Asia and Northeast Asia. The situation is opposite for Central Asia.Xueqian SUN Shuanglin LI Xiaowei HONG Riyu LU 2019Advances in Atmospheric Sciences2019,36,8:3
