| 3 | 基于CMIP6强迫模拟分析人为气溶胶的气候效应(一)——介绍NUIST模式评估结果显示文摘为减少不同气候模式评估气溶胶气候效应的差异,第六次耦合模式比较计划(Coupled Model Intercomparison Project Phase 6,CMIP6)直接给定了人为气溶胶强迫数据。因此,有必要基于此强迫数据重新评估气溶胶气候效应。本研究首先将CMIP6给出的描述人为气溶胶强迫的模块引入南京信息工程大学(Nanjing University of Information Science and Technology,NUIST)的地球系统模式(The NUIST Earth System Model,NESM)。之后,利用NESM模式评估地球辐射收支平衡对此人为气溶胶强迫的响应,并分析模式模拟结果的不确定性。评估给出的人为气溶胶有效辐射强迫为-0.45(±0.28)W·m^-2。其中,气溶胶直接辐射效应为-0.34(±0.01)W·m^-2,与第二次气溶胶比较计划(The second phase of Aerosol Comparisons between Observations and Models,AeroComⅡ)的评估结果基本一致;气溶胶对云辐射强迫的影响(包括半直接效应和间接效应)为-0.10(±0.30)W·m^-2,明显受到模式内部变率的干扰,具有较大的不确定性。 | 史湘军 沈沛洁 朱寿鹏 吉璐莹 张海鹏 刘娇娇 陈伯民 李震坤 | 2020 | 大气科学学报2020，43，3： | 5 |
| 4 | Arctic Climate Changes Based on Historical Simulations(1900-2013) with the CAMS-CSM显示文摘The Chinese Academy of Meteorological Sciences Climate System Model(CAMS-CSM) is a newly developed global climate model that will participate in the Coupled Model Intercomparison Project phase 6. Based on historical simulations(1900-2013), we evaluate the model performance in simulating the observed characteristics of the Arctic climate system, which includes air temperature, precipitation, the Arctic Oscillation(AO), ocean temperature/salinity,the Atlantic meridional overturning circulation(AMOC), snow cover, and sea ice. The model-data comparisons indicate that the CAMS-CSM reproduces spatial patterns of climatological mean air temperature over the Arctic(60°-90°N) and a rapid warming trend from 1979 to 2013. However, the warming trend is overestimated south of the Arctic Circle, implying a subdued Arctic amplification. The distribution of climatological precipitation in the Arctic is broadly captured in the model, whereas it shows limited skills in depicting the overall increasing trend. The AO can be reproduced by the CAMS-CSM in terms of reasonable patterns and variability. Regarding the ocean simulation, the model underestimates the AMOC and zonally averaged ocean temperatures and salinity above a depth of 500 m, and it fails to reproduce the observed increasing trend in the upper ocean heat content in the Arctic. The largescale distribution of the snow cover extent(SCE) in the Northern Hemisphere and the overall decreasing trend in the spring SCE are captured by the CAMS-CSM, while the biased magnitudes exist. Due to the underestimation of the AMOC and the poor quantification of air–sea interaction, the CAMS-CSM overestimates regional sea ice and underestimates the observed decreasing trend in Arctic sea–ice area in September. Overall, the CAMS-CSM reproduces a climatological distribution of the Arctic climate system and general trends from 1979 to 2013 compared with the observations, but it shows limited skills in modeling local trends and interannual variability. | Ting WEI Jian LI Xinyao RONG Wenjie DONG Bingyi WU Minghu DING | 2018 | Journal of Meteorological Research2018，32，6： | 4 |

| 6 | Boreal Summer Intraseasonal Oscillation in the Asian–Pacific Monsoon Region Simulated in CAMS-CSM显示文摘The boreal summer intraseasonal oscillation(BSISO) is simulated by the Climate System Model(CSM) developed at the Chinese Academy of Meteorological Sciences(CAMS), China Meteorological Administration. Firstly, the results indicate that this new model is able to reasonably simulate the annual cycle and seasonal mean of the precipitation, as well as the vertical shear of large-scale zonal wind in the tropics. The model also reproduces the eastward and northward propagating oscillation signals similar to those found in observations. The simulation of BSISO is generally in agreement with the observations in terms of variance center, periodicity, and propagation, with the exception that the magnitude of BSISO anomalous convections are underestimated during both its eastward propagation along the equator and its northward propagation over the Asian–Pacific summer monsoon region. Our preliminary evaluation of the simulated BSISO by CAMS-CSM suggests that this new model has the capability, to a certain extent, to capture the BSISO features, including its propagation zonally along the equator and meridionally over the Asian monsoon region. | Yanjun QI Renhe ZHANG Xinyao RONG Jian LI Lun LI | 2019 | Journal of Meteorological Research2019，33，1： | 2 |
| 7 | 末次盛冰期冰盖对全球季风活动的非对称性影响显示文摘将新研发的南京信息工程大学地球系统模式(NUIST Earth System Model version 1,NESM1)首次应用于古气候模拟中,在Paleoclmate Modelling Intercomparison Project Phase III(PMIP3)框架下设计了工业革命前(Pre-industrial,PI)、末次盛冰期(Last Glacial Maximum,LGM)和增加大陆冰盖(Ice sheets,IS)试验,验证了模式对工业革命前气候和LGM时期气候的模拟能力,并通过增加大陆冰盖试验分析了其对全球季风活动的非对称性影响。结果表明:与PI时期相比,LGM时期的温度和降水均有显著改变。其中,全球平均温度比PI时期降低了4.7℃,全球平均降水减少了0.3 mm·d^(-1),降水对温度变化的敏感性约2.3%·℃^(-1),这与其他耦合模式结果一致。末次盛冰期大陆冰盖对其气候变化有重要贡献,冰盖引起的地表反照率改变与地形抬升作用导致全球平均气温下降1.2℃,降水量减少0.06 mm·d^(-1)。进一步分析表明,末次盛冰期冰盖对全球气候的影响还具有显著南北半球差异,所导致的温度降低和降水减少主要集中在北半球,其中北半球的降温更是高达南半球的5倍;引起北半球季风区年平均降水减少0.24 mm·d^(-1),降水年较差减小0.34 mm·d^(-1),而南半球变化很小。这是由于北半球大幅降温导致的低层水汽含量减小,并与大陆冰盖引起的欧洲大陆和北美大陆反气旋环流共同作用而影响季风活动。在夏季,减少的低层水汽含量与减弱的季风环流使夏季降水显著减少;而在冬季,加强的季风环流能部分抵消水汽含量减小的作用,故冬季降水稍微减弱。此外,在欧洲大陆和北美大陆附近对流层低层反气旋环流作用下,导致亚欧和北美季风活动区域减小。 | 曹剑 吴立广 | 2016 | 气象科学2016，36，4： | 2 |
| 8 | Distinct response of Northern Hemisphere land monsoon precipitation to transient and stablized warming scenarios显示文摘To better understand the climate response under stabilized,overshoot,and transient global warming,four types of ensemble experiments on 1.5℃/2℃ global warming scenarios(i.e.,stabilized 1.5℃,1.5℃ overshoot,stabilized 2℃,and transient 2℃)are elaborately designed using the Nanjing University Information Science and Technology Earth System Model(NESM).Compared with the modern climate(1985–2014),the projected surface air temperature(SAT)change is characterized by a robust‘Northern Hemisphere(NH)-warmer than-Southern Hemisphere(SH)’and‘land-warmer than-ocean’patterns.The projected precipitation change exhibits‘NH-wetter than-SH’pattern in the tropics.Although the response of SAT and precipitation climatology show similar pattern between stabilized and overshoot scenarios,some significant differences are still found.The projected change in the Northern Hemisphere land monsoon precipitation(NHLMP)is 30% larger in the transient 2℃ experiment compared with that in the stabilized 2℃ experiment.The more vigorous NHLMP in the transient global warming scenario is mainly due to the enhanced land-sea thermal contrast and interhemispheric temperature difference.The enlarged land-sea thermal contrast increases the surface pressure gradient between the NH continents and its adjacent oceans,thus enhancing the NH monsoon circulation and moisture convergence.The enhanced interhemispheric temperature difference shifts the Hadley circulation and intertropical convergence zone northward,leading to the enhanced moisture convergence and the shifts of tropical rain band over the NH monsoon region.This result highlights that climate responses may depend on different warming trajectories and,which could facilitate the strategic planning of governments. | CAO Jian ZHAO Hai-Kun | 2020 | Advances in Climate Change Research2020，11，3： | 2 |
| 9 | NUIST地球系统模式模拟热带气旋活动的气候特征分析显示文摘采用恒定的现代外部强迫驱动第一版NUIST地球系统模式,进行了40年全球热带气旋活动模拟,分析了热带气旋活动的气候特征,并与1977—2016年观测资料对比分析。结果表明:该模式能够模拟出与热带气旋类似的结构特征,在热带气旋活动活跃的海区,模拟热带气旋生成的空间分布和影响范围与观测基本一致,但是各个海区热带气旋的生成频数与观测还存在差异。除了北印度洋海区,各个海区热带气旋生成频数的季节变化与观测相似。模式在西北太平洋海区模拟结果最好,能模拟出热带气旋的生成范围和盛行路径;在北印度洋地区模拟结果较差,北印度洋海区的相对涡度模拟与观测存在较大差异,这是模式未能模拟出北印度洋热带气旋双峰特征的主要原因。 | 吴启蒙 吴立广 曹剑 | 2019 | 气候变化研究进展2019，15，2： | 1 |
| 10 | NUIST地球系统模式模拟ENSO对西北太平洋热带气旋活动的影响显示文摘地球系统模式已经逐步成为研究热带气旋(TC)活动气候变化的重要工具之一,之前的研究发现南京信息工程大学地球系统模式(NESM)高分辨率版本可以较好地模拟全球海温分布及TC活动的气候特征。本研究进一步分析了NESM地球系统模式模拟西北太平洋TC活动的年际变化,并与1967~2016年观测的TC活动进行对比。NESM模式高分辨率版本能够较好地模拟西北太平洋平均海温及与ENSO事件联系的海温异常变化特点,对El Nino事件发生时西北太平洋TC的生成频数和路径分布的模拟较好,也能模拟El Nino年TC生成位置比La Nina年偏东的特征,但是未能模拟出TC平均生命周期和Nino3.4地区海温的相关性。并且模式模拟的La Nina年TC的生成位置偏东,主要原因是模拟La Nina年季风槽平均位置偏东。研究结果有助于进一步改进NESM模式和利用NESM模式研究TC活动。 | 吴启蒙 吴立广 曹剑 | 2022 | 大气科学2022，46，2： | 0 |
