| 1 | Paleoclimate Modeling in China: A Review显示文摘This paper provides a review of paleoclimate modeling activities in China. Rather than attempt to cover all topics, we have chosen a few climatic intervals and events judged to be particularly informative to the international community. In historical climate simulations, changes in solar radiation and volcanic activity explain most parts of reconstructions over the last millennium prior to the industrial era, while atmospheric greenhouse gas concentrations play the most important role in the20 th century warming over China. There is a considerable model–data mismatch in the annual and boreal winter temperature change over China during the mid-Holocene [6000 years before present(ka BP)], while coupled models with an interactive ocean generally perform better than atmospheric models. For the Last Glacial Maximum(21 ka BP), climate models successfully reproduce the surface cooling trend over China but fail to reproduce its magnitude, with a better performance for coupled models. At that time, reconstructed vegetation and western Pacific sea surface temperatures could have significantly affected the East Asian climate, and environmental conditions on the Qinghai–Tibetan Plateau were most likely very different to the present day. During the late Marine Isotope Stage 3(30–40 ka BP), orbital forcing and Northern Hemisphere glaciation, as well as vegetation change in China, were likely responsible for East Asian climate change. On the tectonic scale,the Qinghai–Tibetan Plateau uplift, the Tethys Sea retreat, and the South China Sea expansion played important roles in the formation of the East Asian monsoon-dominant environment pattern during the late Cenozoic. | JIANG Dabang YU Ge ZHAO Ping CHEN Xing LIU Jian LIU Xiaodong WANG Shaowu ZHANG Zhongshi YU Yongqiang LI Yuefeng JIN Liya XU Ying JU Lixia ZHOU Tianjun YAN Xiaodong | 2015 | Advances in Atmospheric Sciences2015，32，2： | 12 |
| 2 | Influence of Major Stratospheric Sudden Warming on the Unprecedented Cold Wave in East Asia in January 2021显示文摘An unprecedented cold wave intruded into East Asia in early January 2021 and led to record-breaking or historical extreme low temperatures over vast regions.This study shows that a major stratospheric sudden warming(SSW)event at the beginning of January 2021 exerted an important influence on this cold wave.The major SSW event occurred on 2 January 2021 and subsequently led to the displacement of the stratospheric polar vortex to the East Asian side.Moreover,the SSW event induced the stratospheric warming signal to propagate downward to the mid-to-lower troposphere,which not only enhanced the blocking in the Urals-Siberia region and the negative phase of the Arctic Oscillation,but also shifted the tropospheric polar vortex off the pole.The displaced tropospheric polar vortex,Ural blocking,and another downstream blocking ridge over western North America formed a distinct inverted omega-shaped circulation pattern(IOCP)in the East Asia-North Pacific sector.This IOCP was the most direct and impactful atmospheric pattern causing the cold wave in East Asia.The IOCP triggered a meridional cell with an upward branch in East Asia and a downward branch in Siberia.The meridional cell intensified the Siberian high and low-level northerly winds,which also favored the invasion of the cold wave into East Asia.Hence,the SSW event and tropospheric circulations such as the IOCP,negative phase of Arctic Oscillation,Ural blocking,enhanced Siberian high,and eastward propagation of Rossby wave eventually induced the outbreak of an unprecedented cold wave in East Asia in early January 2021. | Yingxian ZHANG Dong SI Yihui DING Dabang JIANG Qingquan LI Guofu WANG | 2022 | Advances in Atmospheric Sciences2022，39，4： | 5 |
| 3 | Influence of October Eurasian Snow on Winter Temperature over Northeast China显示文摘This paper addresses the interannual variation of winter air temperature over Northeast China and its connection to preceding Eurasian snow cover.The results show that there is a significant negative correlation between October Eurasian snow cover and following-winter air temperature over Northeast China.The snow cover located in eastern Siberia and to the northeast of Lake Baikal plays an important role in the winter air temperature anomaly.More(less)eastern Siberia snow in October can cause an atmospheric circulation anomaly pattern in which the atmospheric pressure is higher(lower)than normal in the polar region and lower(higher)in the northern mid-high latitudes.Due to the persistence of the eastern Siberia snow from October to the following winter,the winter atmospheric anomaly is favorable(unfavorable)to the widespread movement of cold air masses from the polar region toward the northern mid-high latitudes and,hence,lower(higher)temperature over Northeast China.Simultaneously,when the October snow cover is more(less),the SST in the northwestern Pacific is continuously lower(higher)as a whole; then,the Aleutian low and the East Asia trough are reinforced(weakened),favoring the lower(higher)temperature over Northeast China. | Huanlian LI Huijun WANG Dabang JIANG | 2017 | Advances in Atmospheric Sciences2017，34，1： | 4 |

| 9 | Mid-Pliocene Westerlies from Plio MIP Simulations显示文摘The midlatitude westerlies are one of the major components of the global atmospheric circulation. They play an important role in midlatitude weather and climate, and are particularly significant in interpreting aeolian sediments. In this study, we analyzed the behavior and the possible mechanism involved in the change of the westerlies, mainly in terms of the jet stream position, in the mid-Pliocene warm period(3.3 to 3.0 million years ago) using simulations of 15 climate models from the Pliocene Model Intercomparison Project(Plio MIP). Compared to the reference period, the mid-Pliocene midlatitude westerlies generally shifted poleward(approximately 3.6 of latitude in the Northern Hemisphere and 1.9 of latitude in the Southern Hemisphere at 850 h Pa level) with a dipole pattern. The dipole pattern of the tropospheric zonal wind anomalies was closely related to the change of the tropospheric meridional temperature gradient as a result of thermal structure adjustment.The poleward shift of the midlatitude westerly jet corresponded to the poleward shift of the mean meridional circulation.The sea surface temperatures and sea ice may have affected the simulated temperature structure and zonal winds, causing the spread of the westerly anomalies in the mid-Pliocene between the atmosphere-only and coupled atmosphere–ocean general circulation model simulations. | LI Xiangyu JIANG Dabang ZHANG Zhongshi ZHANG Ran TIAN Zhiping YAN Qing | 2015 | Advances in Atmospheric Sciences2015，32，7： | 0 |
