| 1 | The Change of North China Climate in Transient Simulations Using the IPCC SRES A2 and B2 Scenarios with a Coupled Atmosphere-Ocean General Circulation Model显示文摘This paper applies the newest emission scenarios of the sulfur and greenhouse gases, namely IPCCSRES A2 and B2 scenarios, to investigate the change of the North China climate with an atmosphere-oceancoupled general circulation nodel. In the last three decades of the 21st century, the global warming enlargesthe land-sea thermal contrast, and hence, causes the East Asian summer (winter) monsoon circulation tobe strengthened (weakened). The rainfall seasonality strengthens and the summer precipitation increasessignificantly in North China. It is suggested that the East Asian rainy area would expand northward toNorth China in the last three decades of the 21st century. In addition, the North China precipitationwould increase significantly in September. In July, August, and September, the interannual variability ofthe precipitation enlarges evidently over North China, implying a risk of flooding in the future. | 布和朝鲁 Ulrich CUBASCH 林永辉 纪立人 | 2003 | Advances in Atmospheric Sciences2003，20，5： | 31 |
| 2 | Simulation of the future change of East Asian monsoon climate using the IPCC SRES A2 and B2 scenarios显示文摘In this paper, we applied the newest emission scenarios of the sulfur and greenhouse gases, i.e. Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenarios (SRES) A2 and B2 scenarios, to investigating the change of the East Asian climate in the last three decades of the 21st century with an atmosphere-ocean coupled general circulation model. The global warming enlarges the land-sea thermal contrast and, hence, enhances (reduces) the East Asian summer (winter) monsoon circulation. The precipitation from the Yangtze and Huaihe river valley to North China increases significantly. In particular, the strong rainfall increase over North China implies that the East Asian rainy area would expand northward. In addition, from the southeastern coastal area to North China, the rainfall would increase significantly in September, implying that the rainy period of the East Asian monsoon would be prolonged about one month. In July, August and September, the interannual variability of the precipitation enhances evidently over North China, meaning a risk of flooding in the future. | BUEH Cholaw LASG, Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China | 2003 | Chinese Science Bulletin2003，48，10： | 33 |

| 4 | Projections of the East Asian Winter Monsoon under the IPCC AR5 Scenarios Using a Coupled Model:IAP_FGOALS显示文摘Responses of the East Asian winter monsoon(EAWM) in future projections were studied based on two core future projections of CMIP5 in coordinated experiments with the IAP-coupled model FGOALS2-s.The projected changes of EAWM in climatology,seasonality,and interannual variability are reported here;the projections indicated strong warming in winter season.Warming increased with latitude,ranging from 1 C to 3 C in the Representative Concentration Pathways simulation RCP4.5 projection(an experiment that results in additional radiative forcing of ~4.5 W m 2 in 2100) and from 4 C to 9 C in the RCP8.5 projection(an experiment that results in additional radiative forcing of ~8.5 W m 2 in 2100).The northerly wind along the East Asian coastal region became stronger in both scenarios,indicating a stronger EAWM.Accordingly,interannual variability(described by the standard deviation of temperature) increased around the South China Sea and lower latitudes and decreased over eastern China,especially in North China.The two EAWM basic modes,defined by the temperature EOF analysis over East Asia,were associated with the Arctic Oscillation(AO) and stratospheric polar vortex.The future projections revealed more total variance attributable to the secondary mode,suggesting additional influences from the stratosphere.The correlation between AO and the leading mode decreased,while the correlation between AO and the secondary mode increased,implying increased complexity regarding the predictability of EAWM interannual variations in future projections. | 魏科 包庆 | 2012 | Advances in Atmospheric Sciences2012，29，6： | 5 |
| 5 | The Impact of Boreal Autumn SST Anomalies over the South Pacific on Boreal Winter Precipitation over East Asia显示文摘The possible mechanism behind the variability in the dipole pattern of boreal winter precipitation over East Asia is analyzed in this study. The results show that the SST anomalies(SSTAs) over the South Pacific Ocean(SPO) in boreal autumn are closely related to the variability in the dipole pattern of boreal winter precipitation over East Asia. The physical link between the boreal autumn SPO SSTAs and the boreal winter East Asian precipitation dipole pattern is shown to mainly be the seasonal persistence of the SPO SSTAs themselves. The seasonal persistence of the SPO SSTAs can memorize and transport the signal of the boreal autumn SSTAs to the following winter, and then stimulates a meridional teleconnection pattern from the SH to the NH, resulting in a meridional dipole pattern of atmospheric circulation over East Asia in boreal winter. As a major influencing factor, this dipole pattern of the atmospheric circulation can finally lead to the anomalous precipitation dipole pattern over East Asia in boreal winter. These observed physical processes are further confirmed in this study through numerical simulation. The evidence from this study, showing the impact of the SPO SSTAs in boreal autumn,not only deepens our understanding of the variability in East Asian boreal winter precipitation, but also provides a potentially useful predictor for precipitation in the region. | Juan AO Jianqi SUN | 2016 | Advances in Atmospheric Sciences2016，33，5： | 3 |
| 6 | Changes in the East Asian Cold Season since 2000显示文摘Using NCEP-NCAR reanalysis data and observational data from meteorological stations in China, the evolution of the East Asian cold season (EACS) and its long-term changes after 2000 were studied. A monsoon tendency index (MTI), defined as the temporal di?erence of the East Asian monsoon index, indi- cates that the winter monsoon setup has been postponed in autumn, while the setup has quickened in early winter. In mid winter, the EACS breakdown process has accelerated, while it has lingered in late winter. The authors suggest that the postponement of monsoon setup in autumn may be caused by strong global warming at the lower levels, which further limits the setup time period and leads to the quickening of the setup process in early winter. Meanwhile, a north-south seesaw of temperature tendency change in China can be observed in December and February, which may be related to large-scale circulation changes in the stratosphere, characterized by a polar warming in mid winter and polar cooling in early spring. This linkage is possibly caused by the dynamical coupling between stratosphere and troposphere, via the variation of planetary wave activities. In spring, the speed of the EACS breakdown has decreased, which favors the revival of the EACS in East Asia. | 魏科 陈文 周文 | 2011 | Advances in Atmospheric Sciences2011，28，1： | 2 |
| 7 | Interdecadal Variations of Cold Air Activities in Northeast China during Springtime显示文摘Based on the daily mean temperature data of CN05.2 from 1961 to 2012, cold events(CEs) are first divided into two categories according to their duration: strong cold events(SCEs) and weak cold events(WCEs). Then, the characteristics of CEs, SCEs, and WCEs during springtime are investigated. The results indicate that in the pre-1990 s epoch, ENSO and Arctic Oscillation events in the previous winter are closely related to SCEs in the following spring. The multidecadal variations of CEs, SCEs, and WCEs are obvious. The intensity trend for SCEs is significantly negative, but it seems less apparent for WCEs.Further analysis reveals that when both SCEs and WCEs occur, a typical East Asian trough in the 850-h Pa wind field, whose northwesterly wind component invades Northeast China(NEC) and causes freezing days, can be found in every decade. For the SCEs, a cold vortex, with its center located over Okhotsk and northeasterly current affecting NEC, is found as an additional feature. For the WCEs, the cold vortex is located in Karafuto and its northwesterly airflow intrudes into NEC. As for the difference between SCEs and WCEs, the northwestern flow is weaker while the northeastern counterpart is stronger during the SCEs,in all decades. In the Takaya–Nakamura flux and divergence fields, for the SCEs, a divergence center exists over NEC; and over its downstream regions, a stronger divergence center appears, not like a wave train.However, the opposite is the case for the WCEs; moreover, the wave train appears clearly during the WCEs,which means that the wave energy can propagate and dissipate more easily during WCEs. | 李尚锋 姜大膀 廉毅 姚耀显 | 2016 | Journal of Meteorological Research2016，30，5： | 1 |
| 8 | 与EAWM相关的海陆气相互作用及亚洲夏季风(英文)显示文摘基于观测资料分析,本文讨论了与东亚冬季风(EAWM)异常活动相联系的海-陆-气系统的特征,指出它往往是随后亚洲夏季风异常的一个信号。我们分析并确定了一类重要的海气耦合模态,即EAWM。它所包含的海-气双向相互作用,使该模态的SSTA分布得以发展和持续。特别是在西太平洋和南海等关键地区,SSTA异常将从冬季维持到夏季。在强冬季风年,青藏高原积雪冬季在其东部出现负距平区,春季则延伸到高原西北部。SSTA及高原积雪分布,共同构成调制亚洲季风环流的重要因子,它将有助于1)随后南海季风和季风降水的增强;2)梅雨期西太平洋副高偏北,长江流域少雨;3)夏季我国东北和日本多雨;4)阿拉伯海和印度东北多雨,而印度西南部及孟加拉湾少雨。总之,强EAWM及相联的海气相互作用,一定程度上,预示着亚洲夏季风的活动特征。 | 布和朝鲁 纪立人 孙淑清 崔茂常 | 2001 | Advances in Atmospheric Sciences2001，18，5： | 0 |
