| 1 | Influence of the Tibetan Plateau uplift on the Asian monsoon-arid environment evolution显示文摘As one of the most important geological events in Cenozoic era,the uplift of the Tibetan Plateau(TP)has had profound influences on the Asian and global climate and environment evolution.During the past four decades,many scholars from China and abroad have studied climatic and environmental effects of the TP uplift by using a variety of geological records and paleoclimate numerical simulations.The existing research results enrich our understanding of the mechanisms of Asian monsoon changes and interior aridification,but so far there are still a lot of issues that need to be thought deeply and investigated further.This paper attempts to review the research on the influence of the TP uplift on the Asian monsoon-arid environment,summarize three types of numerical simulations including bulk-plateau uplift,phased uplift and sub-regional uplift,and especially to analyze regional differences in responses of climate and environment to different forms of tectonic uplifts.From previous modeling results,the land-sea distribution and the Himalayan uplift may have a large effect in the establishment and development of the South Asian monsoon.However,the formation and evolution of the monsoon in northern East Asia,the intensified dryness north of the TP and enhanced Asian dust cycle may be more closely related to the uplift of the main body,especially the northern part of the TP.In this review,we also discuss relative roles of the TP uplift and other impact factors,origins of the South Asian monsoon and East Asian monsoon,feedback effects and nonlinear responses of climatic and environmental changes to the plateau uplift.Finally,we make comparisons between numerical simulations and geological records,discuss their uncertainties,and highlight some problems worthy of further studying. | LIU XiaoDong DONG BuWen | 2013 | Chinese Science Bulletin2013，58，34： | 36 |
| 2 | 青藏高原隆升对亚洲季风-干旱环境演化的影响显示文摘青藏高原隆升是新生代最重要的地质事件之一,对亚洲乃至全球气候和环境演化都产生了深刻的影响.近40年来中外学者利用各种地质记录和气候数值模拟研究了青藏高原隆升的气候环境效应,丰富了对亚洲季风变迁和亚洲内陆干旱化机制的认识,但至今仍存在许多需深入思考和探讨的问题.本文试图回顾青藏高原隆升对亚洲季风-干旱环境演化影响的研究,对高原整体隆升、阶段性隆升和区域隆升3类数值模拟试验的结果进行总结,重点分析不同形式的构造隆升在气候和环境效应上的区域差异.从目前的数值模拟结果来看,海陆分布和喜马拉雅山的隆升可能对南亚季风的建立和发展具有较大的作用,而东亚北方季风的形成发展、高原北侧干旱化加剧和亚洲粉尘循环增强则可能与青藏高原主体、特别是高原北部的隆升关系更为密切.该文也对青藏高原隆升与其他影响因子作用的对比、南亚季风和东亚季风的起源、高原隆升过程中的反馈效应与气候环境变化的非线性响应、数值模拟与地质记录的对比及其不确定性等进行讨论,并探讨了未来需深化研究的一些问题. | 刘晓东 DONG BuWen | 2013 | 科学通报2013，58，28： | 36 |
| 3 | Response of the Asian Summer Monsoon to Weakening of Atlantic Thermohaline Circulation显示文摘Various paleoclimate records have shown that the Asian monsoon was punctuated by numerous sub-orbital time-scale events, and these events were coeval with those that happened in the North Atlantic. This study investigates the Asian summer monsoon responses to the Atlantic Ocean forcing by applying an additional freshwater flux into the North Atlantic. The simulated results indicate that the cold North Atlantic and warm South Atlantic induced by the weakened Atlantic thermohaline circulation (THC) due to the freshwater flux lead to significantly suppressed Asian summer monsoon. The authors analyzed the detailed processes of the Atlantic Ocean forcing on the Asian summer monsoon, and found that the atmospheric teleconnection in the eastern and central North Pacific and the atmosphere-ocean interaction in the tropical North Pacific play the most crucial role. Enhanced precipitation in the subtropical North Pacific extends the effects of Atlantic Ocean forcing from the eastern Pacific into the western Pacific, and the atmosphere-ocean interaction in the tropical Pacific and Indian Ocean intensifies the circulation and precipitation anomalies in the Pacific and East Asia. | 陆日宇 Buwen DONG | 2008 | Advances in Atmospheric Sciences2008，25，5： | 19 |
| 4 | Abrupt Summer Warming and Changes in Temperature Extremes over Northeast Asia Since the Mid-1990s: Drivers and Physical Processes显示文摘This study investigated the drivers and physical processes for the abrupt decadal summer surface warming and increases in hot temperature extremes that occurred over Northeast Asia in the mid-1990 s. Observations indicate an abrupt increase in summer mean surface air temperature(SAT) over Northeast Asia since the mid-1990 s. Accompanying this abrupt surface warming, significant changes in some temperature extremes, characterized by increases in summer mean daily maximum temperature(Tmax), daily minimum temperature(Tmin), annual hottest day temperature(TXx), and annual warmest night temperature(TNx) were observed. There were also increases in the frequency of summer days(SU) and tropical nights(TR).Atmospheric general circulation model experiments forced by changes in sea surface temperature(SST)/ sea ice extent(SIE),anthropogenic greenhouse gas(GHG) concentrations, and anthropogenic aerosol(AA) forcing, relative to the period 1964–93, reproduced the general patterns of observed summer mean SAT changes and associated changes in temperature extremes,although the abrupt decrease in precipitation since the mid-1990 s was not simulated. Additional model experiments with different forcings indicated that changes in SST/SIE explained 76% of the area-averaged summer mean surface warming signal over Northeast Asia, while the direct impact of changes in GHG and AA explained the remaining 24% of the surface warming signal. Analysis of physical processes indicated that the direct impact of the changes in AA(through aerosol–radiation and aerosol–cloud interactions), mainly related to the reduction of AA precursor emissions over Europe, played a dominant role in the increase in TXx and a similarly important role as SST/SIE changes in the increase in the frequency of SU over Northeast Asia via AA-induced coupled atmosphere–land surface and cloud feedbacks, rather than through a direct impact of AA changes on cloud condensation nuclei. The modelling results also imply that the abrupt summer surface warming and increases in hot temperature extremes over Northeast Asia since the mid-1990 s will probably sustain in the next few decades as GHG concentrations continue to increase and AA precursor emissions over both North America and Europe continue to decrease. | Buwen DONG Rowan T.SUTTON Wei CHEN Xiaodong LIU Riyu LU Ying SUN | 2016 | Advances in Atmospheric Sciences2016，33，9： | 17 |
| 5 | Where were the monsoon regions and arid zones in Asia prior to the Tibetan Plateau uplift?显示文摘The impact of the Tibetan Plateau uplit on the Asian monsoons and inland arid climates is an important but also controversial question in studies of paleoenvironmental change during the Cenozoic. In order to achieve a good understanding of the background for the formation of the Asian monsoons and arid environments, it is necessary to know the characteristics of the distribution of monsoon regions and arid zones in Asia before the plateau uplit. In this study, we discuss in detail the paterns of distribution of the Asian monsoon and arid regions before the plateau uplit on the basis of modeling results without topography from a global coupled atmosphere–ocean general circulation model, compare our results with previous simulation studies and available biogeological data, and review the uncertainties in the current knowledge. Based on what we know at the moment, tropical monsoon climates existed south of 20?N in South and Southeast Asia before the plateau uplit, while the East Asian monsoon was entirely absent in the extratropics. hese tropical monsoons mainly resulted from the seasonal shits of the Inter-Tropical Convergence Zone. here may have been a quasi-monsoon region in central-southern Siberia. Most of the arid regions in the Asian continent were limited to the latitudes of 20–40?N, corresponding to the range of the subtropical high pressure year-around. In the meantime, the present-day arid regions located in the relatively high latitudes in Central Asia were most likely absent before the plateau uplit. he main results from the above modeling analyses are qualitatively consistent with the available biogeological data. hese results highlight the importance of the uplit of the Tibetan Plateau in the Cenozoic evolution of the Asian climate patern of dry–wet conditions. Future studies should be focused on efects of the changes in land–sea distribution and atmospheric CO2 concentrations before and ater the plateau uplit, and also on cross-comparisons between numerical simulations and geological evidence, so that a comprehensive understanding of the evolution of the Cenozoic paleoenvironments in Asia can be achieved. | Xiaodong Liu Qingchun Guo Zhengtang Guo Zhi-Yong Yin Buwen Dong Robin Smith | 2015 | National Science Review2015，2，4： | 12 |

| 7 | The dynamic and thermodynamic processes dominating the reduction of global land monsoon precipitation driven by anthropogenic aerosols emission显示文摘Changes in monsoon precipitation have profound social and economic impacts as more than two-thirds of the world’s population lives in monsoon regions.Observations show a significant reduction in global land monsoon precipitation during the second half of the 20 th century.Understanding the cause of this change,especially possible anthropogenic origins,is important.Here,we compare observed changes in global land monsoon precipitation during 1948–2005 with those simulated by 5 global climate models participating in the Coupled Model Inter-comparison Project-phase 5(CMIP5)under different external forcings.We show that the observed drying trend is consistent with the model simulated response to anthropogenic forcing and to anthropogenic aerosol forcing in particular.We apply the optimal fingerprinting method to quantify anthropogenic influences on precipitation and find that anthropogenic aerosols may have contributed to 102%(62–144%for the 5–95%confidence interval)of the observed decrease in global land monsoon precipitation.A moisture budget analysis indicates that the reduction in precipitation results from reduced vertical moisture advection in response to aerosol forcing.Since much of the monsoon regions,such as India and China,have been experiencing rapid developments with increasing aerosol emissions in the past decedes,our results imply a further reduction in monsoon precipitation in these regions in the future if effective mitigations to reduce aerosol emissions are not deployed.The observed decline of aerosol emission in China since 2006 helps to alleviate the reducing trend of monsoon precipiptaion. | Tianjun ZHOU Wenxia ZHANG Lixia ZHANG Xuebin ZHANG Yun QIAN Dongdong PENG Shuangmei MA Buwen DONG | 2020 | Science China Earth Sciences2020，63，7： | 7 |
| 8 | The Coupled Model Predictability of the Western North Pacific Summer Monsoon with Different Leading Times显示文摘Leading time length is an important issue for modeling seasonal forecasts. In this study, a comparison of the interannual predictability of the Western North Pacific (WNP) summer monsoon between different leading months was performed by using one-, four-, and sevenmonth lead retrospective forecasts (hindcasts) of four coupled models from Ensembles-Based Predictions of Climate Changes and Their Impacts (ENSEMBLES) for the period of 1960 2005. It is found that the WNP summer anomalies, including lower-tropospheric circulation and precipitation anomalies, can be well predicted for all these leading months. The accuracy of the four-month lead prediction is only slightly weaker than that of the one-month lead prediction, although the skill decreases with the increase of leading months. | LU Ri-Yu LI Chao-Fan Se-Hwan YANG Buwen DONG | 2012 | Atmospheric and Oceanic Science Letters2012，5，3： | 5 |
| 9 | 大陆漂移、高原隆升与新生代亚-非-澳洲季风区和干旱区演化显示文摘亚-非-澳洲季风区和干旱区的面积约占这三大洲陆地总面积的60%以上.基于新生代以来亚-非-澳洲季风和干旱环境以及东半球海陆分布和青藏高原等地形显著变化的地质事实,利用全球海-气耦合模式开展新生代5个特征地质时期气候模拟试验,系统探讨了新生代亚-非-澳洲季风区和干旱区形成演化及其受大陆漂移和高原隆升的影响.结果表明,亚-非-澳洲季风区和干旱区形成的时间和原因明显不同.北非与南非季风在古新世中期已经存在,南亚次大陆季风在始新世印度大陆移入北半球热带后开始出现,而东亚和澳大利亚北部季风在中新世才建立.北非、南非、南亚和澳大利亚热带季风的建立是大陆漂移的位置和热带辐合带季节性迁移共同决定的,而青藏高原的位置和高度则是东亚季风建立的关键因素.北非、南非、亚洲和澳大利亚副热带干旱区的存在取决于大陆的位置和行星尺度副热带高压的控制,阿拉伯半岛和西亚干旱区的发展与区域尺度海陆变迁,特别是古特提斯海的退缩密切相关,而亚洲内陆中纬度干旱区的形成则是青藏高原隆升的结果.这一研究揭示了地球构造边界条件在地质时期区域气候环境形成演化中的重要作用. | 刘晓东 Buwen DONG Zhi-Yong YIN Robin S.SMITH 郭庆春 | 2019 | 中国科学:地球科学2019，49，7： | 5 |
| 10 | Continental drift, plateau uplift, and the evolutions of monsoon and arid regions in Asia, Africa, and Australia during the Cenozoic显示文摘Monsoon and arid regions in the Asia-Africa-Australia(A-A-A) realm occupy more than 60% of the total area of these continents. Geological evidence showed that significant changes occurred to the A-A-A environments of the monsoon and arid regions, the land-ocean configuration in the Eastern Hemisphere, and the topography of the Tibetan Plateau(TP) in the Cenozoic. Motivated by this background, numerical experiments for 5 typical geological periods during the Cenozoic were conducted using a coupled ocean-atmosphere general circulation model to systemically explore the formations and evolutionary histories of the Cenozoic A-A-A monsoon and arid regions under the influences of continental drift and plateau uplift. Results of the numerical experiments indicate that the timings and causes of the formations of monsoon and arid regions in the A-A-A realm were very different. The northern and southern African monsoons existed during the mid-Paleocene, while the South Asian monsoon appeared in the Eocene after the Indian Subcontinent moved into the tropical Northern Hemisphere. In contrast, the East Asian monsoon and northern Australian monsoon were established much later in the Miocene. The establishment of the tropical monsoons in northern and southern Africa, South Asia, and Australia were determined by both the continental drift and seasonal migration of the Inter-Tropical Convergence Zone(ITCZ), while the position and height of the TP were the key factor for the establishment of the East Asian monsoon. The presence of the subtropical arid regions in northern and southern Africa,Asia, and Australia depended on the positions of the continents and the control of the planetary scale subtropical high pressure zones, while the arid regions in the Arabian Peninsula and West Asia were closely related to the retreat of the Paratethys Sea. The formation of the mid-latitude arid region in the Asian interior, on the other hand, was the consequence of the uplift of the TP.These results from this study provide insight to the important roles played by the earth's tectonic boundary conditions in the formations and evolutions of regional climates during geological times. | Xiaodong LIU Buwen DONG Zhi-Yong YIN Robin S.SMITH Qingchun GUO | 2019 | Science China Earth Sciences2019，62，7： | 5 |
| 11 | Interdecadal Enhancement of the Walker Circulation over the Tropical Pacific in the Late 1990s显示文摘The Walker circulation is one of the major components of the large-scale tropical atmospheric circulation and variations in its strength are critical to equatorial Pacific Ocean circulation.It has been argued in the literature that during the 20th century the Walker circulation weakened,and that this weakening was attributable to anthropogenic climate change.By using updated observations,we show that there has been a rapid interdecadal enhancement of the Walker circulation since the late 1990s.Associated with this enhancement is enhanced precipitation in the tropical western Pacific,anomalous westerlies in the upper troposphere,descent in the central and eastern tropical Pacific,and anomalous surface easterlies in the western and central tropical Pacific.The characteristics of associated oceanic changes are a strengthened thermocline slope and an enhanced zonal SST gradient across the tropical Pacific.Many characteristics of these changes are similar to those associated with the mid-1970s climate shift with an opposite sign.We also show that the interdecadal variability of the Walker circulation in the tropical Pacific is inversely correlated to the interdecadal variability of the zonal circulation in the tropical Atlantic.An enhancement of the Walker circulation in the tropical Pacific is associated with a weakening zonal circulation in the tropical Atlantic and vise versa,implying an inter-Atlantic-Pacific connection of the zonal overturning circulation variation.Whether these recent changes will be sustained is not yet clear,but our research highlights the importance of understanding the interdecadal variability,as well as the long-term trends,that influence tropical circulation. | Buwen DONG 陆日宇 | 2013 | Advances in Atmospheric Sciences2013，30，2： | 3 |
| 12 | Revisiting Asymmetry for the Decaying Phases of El Ni?o and La Ni?a显示文摘This study investigated the relationship between the asymmetry in the duration of El Ni?o and La Ni?a and the length of their decaying phases. The results suggested that the duration asymmetry comes from the long decaying ENSO cases rather than the short decaying ones. The evolutions of short decaying El Ni?o and La Ni?a are approximately a mirror image with a rapid decline in the following summer for the warm and cold events. However, a robust asymmetry was found in long decaying cases, with a prolonged and re-intensified La Ni?a in the following winter. The asymmetry for long decaying cases starts from the westward extension of the zonal wind anomalies in a mature winter, and is further contributed to by the air-sea interaction over the tropical Pacific in the following seasons. | CHEN Wei LU Ri-Yu Buwen DONG | 2014 | Atmospheric and Oceanic Science Letters2014，7，4： | 2 |

| 14 | Anthropogenic Influence on Decadal Changes in Concurrent Hot and Dry Events over China around the Mid-1990s显示文摘The frequency and duration of observed concurrent hot and dry events(HDEs) over China during the growing season(April–September) exhibit significant decadal changes across the mid-1990s. These changes are characterized by increases in HDE frequency and duration over most of China, with relatively large increases over southeastern China(SEC), northern China(NC), and northeastern China(NEC). The frequency of HDEs averaged over China in the present day(PD,1994–2011) is double that in the early period(EP, 1964–81);the duration of HDEs increases by 60%. Climate experiments with the Met Office Unified Model(MetUM-GOML2) are used to estimate the contributions of anthropogenic forcing to HDE decadal changes over China. Anthropogenic forcing changes can explain 60%–70% of the observed decadal changes,suggesting an important anthropogenic influence on HDE changes over China across the mid-1990s. Single-forcing experiments indicate that the increase in greenhouse gas(GHG) concentrations dominates the simulated decadal changes,increasing the frequency and duration of HDEs throughout China. The change in anthropogenic aerosol(AA) emissions significantly decreases the frequency and duration of HDEs over SEC and NC, but the magnitude of the decrease is much smaller than the increase induced by GHGs. The changes in HDEs in response to anthropogenic forcing are mainly due to the response of climatological mean surface air temperatures. The contributions from changes in variability and changes in climatological mean soil moisture and evapotranspiration are relatively small. The physical processes associated with the response of HDEs to GHG and AA changes are also revealed. | Qin SU Buwen DONG Fangxing TIAN Nicholas P.KLINGAMAN | 2024 | Advances in Atmospheric Sciences2024，41，2： | 1 |

| 16 | Forced Decadal Changes in Summer Precipitation Characteristics over China:The Roles of Greenhouse Gases and Anthropogenic Aerosols显示文摘We investigated the decadal changes in the different types of summer mean precipitation over China across the mid-1990 s based on observational datasets.The spatial variations in the observed decadal changes were estimated by comparing the present day(PD)time period of 1994–2011 with an earlier period of 1964–1981.The summer total precipitation increased in southern China and decreased in northern China from the early period to the PD.The increases of precipitation in southern China were due to increases in the frequency of heavy and moderate rainfall,whereas the decreases over northern China were mainly due to decreases in the frequency of moderate and light rainfall.Based on a set of numerical experiments using an atmospheric general circulation model coupled with a multilevel mixed-layer ocean model,we found that the increase of precipitation frequency forced by greenhouse gases is the main reason of increasing precipitation over southern and northeastern China,while the decrease of frequency caused by anthropogenic aerosol(AA)induces the decreasing precipitation over northern China.The water vapor flux convergence and water vapor flux strengthen in southern China and northeastern China by anthropogenic greenhouse gases.This distribution is also conducive to precipitation in most of southern China and northeastern China.Under the control of weakened southwesterly winds and 850-h Pa divergence,precipitation decreases over northern and southwestern China by AA. | Bo ZHANG Buwen DONG Ronghua JIN | 2020 | Journal of Meteorological Research2020，34，6： | 0 |
| 17 | Drivers of the Severity of the Extreme Hot Summer of 2015 in Western China显示文摘Western China experienced an extreme hot summer in 2015,breaking a number of temperature records.The summer mean surface air temperature(SAT)anomaly was twice the interannual variability.The hottest daytime temperature(T_(Xx))and warmest night-time temperature(T_(Nx))were the highest in China since 1964.This extreme hot summer occurred in the context of steadily increasing temperatures in recent decades.We carried out a set of experiments to evaluate the extent to which the changes in sea surface temperature(SST)/sea ice extent(SIE)and anthropogenic forcing drove the severity of the extreme summer of 2015 in western China.Our results indicate that about 65%–72% of the observed changes in the seasonal mean SAT and the daily maximumand daily minimum(T_(min))temperatures over western China resulted from changes in boundary forcings,including the SST/SIE and anthropogenic forcing.For the relative role of individual forcing,the direct impact of changes in anthropogenic forcing explain about 42% of the SAT warming and 60%(40%)of the increase in T_(Nx) and T_(min)(T_(Xx) and T_(max))in the model response.The changes in SST/SIE contributed to the remaining surface warming and the increase in hot extremes,which are mainly the result of changes in the SST over the Pacific Ocean,where a super El Ni?o event occurred.Our study indicates a prominent role for the direct impact of anthropogenic forcing in the severity of the extreme hot summer in western China in 2015,although the changes in SST/SIE,as well as the internal variability of the atmosphere,also made a contribution. | Wei CHEN Buwen DONG | 2018 | Journal of Meteorological Research2018，32，6： | 0 |
