| 2 | The Summer Snow Cover Anomaly over the Tibetan Plateau and Its Association with Simultaneous Precipitation over the Mei-yu–Baiu region显示文摘The summer snow anomalies over the Tibetan Plateau(TP) and their effects on climate variability are often overlooked, possibly due to the fact that some datasets cannot properly capture summer snow cover over high terrain. The satellite-derived Equal-Area Scalable Earth grid(EASE-grid) dataset shows that snow still exists in summer in the western part and along the southern flank of the TP. Analysis demonstrates that the summer snow cover area proportion(SCAP) over the TP has a significant positive correlation with simultaneous precipitation over the mei-yu–baiu(MB) region on the interannual time scale. The close relationship between the summer SCAP and summer precipitation over the MB region could not be simply considered as a simultaneous response to the Silk Road pattern and the SST anomalies in the tropical Indian Ocean and tropical central-eastern Pacific. The SCAP anomaly has an independent effect and may directly modulate the land surface heating and, consequently, vertical motion over the western TP, and concurrently induce anomalous vertical motion over the North Indian Ocean via a meridional vertical circulation. Through a zonal vertical circulation over the tropics and a Kelvin wave-type response, anomalous vertical motion over the North Indian Ocean may result in an anomalous high over the western North Pacific and modulate the convective activity in the western Pacific warm pool, which stimulates the East Asia–Pacific(EAP) pattern and eventually affects summer precipitation over the MB region. | LIU Ge WU Renguang ZHANG Yuanzhi NAN Sulan | 2014 | Advances in Atmospheric Sciences2014，31，4： | 12 |
| 3 | Synergistic Contribution of Precipitation Anomalies over Northwestern India and the South China Sea to High Temperature over the Yangtze River Valley显示文摘This study explores the characteristics of high temperature anomalies over eastern China and associated influencing factors using observations and model outputs.Results show that more long-duration(over 8 days) high temperature events occur over the middle and lower reaches of the Yangtze River Valley(YRV) than over the surrounding regions,and control most of the interannual variation of summer mean temperature in situ.The synergistic effect of summer precipitation over the South China Sea(SCS) region(18°–27°N,115°–124°E) and the northwestern India and Arabian Sea(IAS) region(18°–27°N,60°–80°E) contributes more significantly to the variation of summer YRV temperature,relative to the respective SCS or IAS precipitation anomaly.More precipitation(enhanced condensational heating) over the SCS region strengthens the western Pacific subtropical high(WPSH) and simultaneously weakens the westerly trough over the east coast of Asia,and accordingly results in associated high temperature anomalies over the YRV region through stimulating an East Asia–Pacific(EAP) pattern.More precipitation over the IAS region further adjusts the variations of the WPSH and westerly trough,and eventually reinforces high temperature anomalies over the YRV region.Furthermore,the condensational heating related to more IAS precipitation can adjust upper-tropospheric easterly anomalies over the YRV region by exciting a circumglobal teleconnection,inducing cold horizontal temperature advection and related anomalous descent,which is also conducive to the YRV high temperature anomalies.The reproduction of the above association in the model results indicates that the above results can be explained both statistically and dynamically. | LIU Ge WU Renguang SUN Shuqing WANG Huimei | 2015 | Advances in Atmospheric Sciences2015，32，9： | 8 |
| 4 | On the Weakened Relationship between Spring Arctic Oscillation and Following Summer Tropical Cyclone Frequency over the Western North Pacific:A Comparison between 1968–1986 and 1989–2007显示文摘This study documents a weakening of the relationship between the spring Arctic Oscillation(AO) and the following summer tropical cyclone(TC) formation frequency over the eastern part(150?–180?E) of the western North Pacific(WNP). The relationship is strong and statistically significant during 1968–1986,but becomes weak during 1989–2007. The spring AOrelated SST,atmospheric dynamic,and thermodynamic conditions are compared between the two epochs to understand the possible reasons for the change in the relationship. Results indicate that the spring AO leads to an El Ni ?no-like SST anomaly,lower-level anomalous cyclonic circulation,upper-level anomalous anticyclonic circulation,enhanced ascending motion,and a positive midlevel relative humidity anomaly in the tropical western–central Pacific during 1968–1986,whereas the AOrelated anomalies in the above quantities are weak during 1989–2007. Hence,the large-scale dynamic and thermodynamic anomalies are more favorable for TC formation over the eastern WNP during 1968–1986 than during 1989–2007. | CAO Xi CHEN Shangfeng CHEN Guanghua CHEN Wen WU Renguang | 2015 | Advances in Atmospheric Sciences2015，32，10： | 6 |
| 5 | Intensified Impact of Northern Tropical Atlantic SST on Tropical Cyclogenesis Frequency over the Western North Pacific after the Late 1980s显示文摘Previous studies suggest that spring SST anomalies over the northern tropical Atlantic(NTA) affect the tropical cyclone(TC) activity over the western North Pacific(WNP) in the following summer and fall. The present study reveals that the connection between spring NTA SST and following summer–fall WNP TC genesis frequency is not stationary. The influence of spring NTA SST on following summer–fall WNP TC genesis frequency is weak and insignificant before, but strong and significant after, the late 1980 s. Before the late 1980 s, the NTA SST anomaly-induced SST anomalies in the tropical central Pacific are weak, and the response of atmospheric circulation over the WNP is not strong. As a result, the connection between spring NTA SST and following summer–fall WNP TC genesis frequency is insignificant in the former period. In contrast,after the late 1980 s, NTA SST anomalies induce pronounced tropical central Pacific SST anomalies through an Atlantic–Pacific teleconnection. Tropical central Pacific SST anomalies further induce favorable conditions for WNP TC genesis,including vertical motion, mid-level relative humidity, and vertical zonal wind shear. Hence, the connection between NTA SST and WNP TC genesis frequency is significant in the recent period. Further analysis shows that the interdecadal change in the connection between spring NTA SST and following summer–fall WNP TC genesis frequency may be related to the climatological SST change over the NTA region. | Xi CAO Shangfeng CHEN Guanghua CHEN Renguang WU | 2016 | Advances in Atmospheric Sciences2016，33，8： | 5 |
| 6 | Regional Meteorological Patterns for Heavy Pollution Events in Beijing显示文摘The present study investigates meteorological conditions for the day-to-day changes of particulate matter(PM)concentration in Beijing city during the period 2008–2015. The local relationship of PM concentration to surface air temperature, pressure, wind speed, and relative humidity displays seasonal changes and year-to-year variations. The average correlation coefficient with PM10 in spring, summer, fall, and winter is 0.45, 0.40, 0.38, and 0.30 for air temperature; –0.45, –0.05, –0.40, and –0.45 for pressure; 0.13, 0.04, 0.53, and 0.50 for relative humidity; and –0.18,–0.11, –0.45, and –0.33 for wind speed. A higher correlation with wind speed is obtained when wind speed leads by half a day. The heavily polluted and clean days, which are defined as the top and bottom 10% of the PM values, show obvious differences in the regional distribution of air temperature, pressure, and wind. Polluted days correspond to higher air temperature in all the four seasons, lower sea level pressure and anomalous southerly winds to the south and east of Beijing in spring, fall, and winter, and a northwest–southeast contrast in the pressure anomaly and anomalous southerly winds in summer. Higher relative humidity is observed on polluted days in fall and winter. The polluted days are preceded by an anomalous cyclone moving from the northwest, accompanied by lower pressure and higher air temperature, in all four seasons. This feature indicates the impacts of moving weather systems on local meteorological conditions for day-to-day air quality changes in Beijing. | ting you renguang wu gang huang guangzhou fan | 2017 | Journal of Meteorological Research2017，31，3： | 4 |

| 8 | An enhanced influence of sea surface temperature in the tropical northern Atlantic on the following winter ENSO since the early 1980s显示文摘已有研究指出春季热带北大西洋海温对随后冬季ENSO事件的发生存在显著的影响。该研究发现它们的联系在20世纪80年代初以后显著增强。20世纪80年代初以后,春季热带北大西洋海温为正异常时,副热带东北太平洋存在显著的异常气旋环流,同时异常沃克环流在热带中东太平洋引起显著的异常下沉运动。异常气旋环流西侧的东北风异常增强气候态的风速,导致负海温异常。负海温异常通过Gill型大气响应使得热带西北太平洋产生异常的反气旋环流。同时,热带中东太平洋的沃克环流异常下沉运动也对热带西北太平洋异常反气旋环流的形成起到一定作用。热带西北太平洋反气旋环流南侧的东风异常通过海洋动力过程对随后冬季ENSO产生影响。因此,春季热带北大西洋海温对冬季ENSO存在显著的影响。然而,20世纪80年代以前,春季热带北大西洋海温相关的热带东北太平洋异常气旋环流和热带地区的异常沃克环流不显著,从而不能在热带西北太平洋产生异常反气旋。所以,20世纪80年代以前,春季热带北大西洋海温对冬季ENSO的影响不显著。进一步的分析指出,春季热带北大西洋海温对ENSO影响的年代际变化可能与热带北大西洋降水气候态的年代际变化有关。 | CHEN Shang-Feng WU Renguang | 2017 | Atmospheric and Oceanic Science Letters2017，10，2： | 3 |
| 9 | Causes and Predictability of the 2021 Spring Southwestern China Severe Drought显示文摘In the spring of 2021,southwestern China(SWC)experienced extreme drought,accompanied by the highest seasonal-mean temperature record since 1961.This drought event occurred in the decaying phase of a La Niña event with negative geopotential height anomalies over the Philippine Sea,which is distinct from the historical perspective.Historically,spring drought over SWC is often linked to El Niño and strong western North Pacific subtropical high.Here,we show that the extreme drought in the spring of 2021 may be mainly driven by the atmospheric internal variability and amplified by the warming trend.Specifically,the evaporation increase due to the high temperature accounts for about 30%of drought severity,with the contributions of its linear trend portion being nearly 20%and the interannual variability portion being about 10%.Since the sea surface temperature forcing from the tropical central and eastern Pacific played a minor role in the occurrence of drought,it is a challenge for a climate model to capture the 2021 SWC drought beyond one-month lead times. | Yunyun LIU Zeng-Zhen HU Renguang WU Xing YUAN | 2022 | Advances in Atmospheric Sciences2022，39，10： | 2 |
| 10 | Differences in Meteorological Conditions between Days with Persistent and Non-Persistent Pollution in Beijing, China显示文摘We compared the regional synoptic patterns and local meteorological conditions during persistent and non-persistent pollution events in Beijing using US NCEP–Department of Energy reanalysis outputs and observations from meteorological stations. The analysis focused on the impacts of high-frequency(period < 90 days) variations in meteorological conditions on persistent pollution events(those lasting for at least 3 days). Persistent pollution events tended to occur in association with slow-moving weather systems producing stagnant weather conditions, whereas rapidly moving weather systems caused a dramatic change in the local weather conditions so that the pollution event was short-lived. Although Beijing was under the influence of anomalous southerly winds in all four seasons during pollution events, notable differences were identified in the regional patterns of sea-level pressure and local anomalies in relative humidity among persistent pollution events in different seasons. A region of lower pressure was present to the north of Beijing in spring, fall, and winter, whereas regions of lower and higher pressures were observed northwest and southeast of Beijing, respectively, in summer. The relative humidity near Beijing was higher in fall and winter, but lower in spring and summer. These differences may explain the seasonal dependence of the relationship between air pollution and the local meteorological variables. Our analysis showed that the temperature inversion in the lower troposphere played an important part in the occurrence of air pollution under stagnant weather conditions.Some results from this study are based on a limited number of events and thus require validation using more data. | Ting YOU Renguang WU Gang HUANG | 2018 | Journal of Meteorological Research2018，32，1： | 2 |
| 11 | Autumn Snow Cover Variability over Northern Eurasia and Roles of Atmospheric Circulation显示文摘This study analyzes the variability of northern Eurasian snow cover(SC) in autumn and the impacts of atmospheric circulation changes. The region of large SC variability displays a southward shift from September to November, following the seasonal progression of the transition zones of surface air temperature(SAT). The dominant pattern of SC variability in September and October features a zonal distribution, and that in November displays an obvious west–east contrast. Surface air cooling and snowfall increase are two factors for larger SC. The relative contribution of SAT and snowfall changes to SC, however, varies with the region and depends upon the season. The downward longwave radiation and atmospheric heat advection play important roles in SAT changes. Anomalous convergence of water vapor flux contributes to enhanced snowfall.The changes in downward longwave radiation are associated with those in atmospheric water content and column thickness.Changes in snowfall and the transport of atmospheric moisture determine the atmospheric moisture content in September and October, and the snowfall appears to be a main factor for atmospheric moisture change in November. These results indicate that atmospheric circulation changes play an important role in snow variability over northern Eurasia in autumn. Overall, the coupling between autumn Eurasian snow and atmospheric circulation may not be driven by external forcing. | Kunhui YE Renguang WU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |
