Atlantic Multidecadal Oscillation modulates the impacts of Arctic sea ice decline
Li, Fei; Orsolini, Yvan; Wang, Huijun; Gao, Yongqi; He, Shengping (Peer reviewed; Journal article, 2018-03)The Arctic sea ice cover has been rapidly declining in the last two decades, concurrent with a shift in the Atlantic Multidecadal Oscillation (AMO) to its warm phase around 1996/1997. Here we use both observations and model ... -
The Atlantic Multidecadal Variability phase-dependence of teleconnection between the North Atlantic Oscillation in February and the Tibetan Plateau in March
Li, Jingyi; Li, Fei; He, Shengping; Wang, Huijun; Orsolini, Yvan J. (Journal article; Peer reviewed, 2021)The Tibetan Plateau (TP), referred to as the “Asian water tower,” contains one of the largest land ice masses on Earth. The local glacier shrinkage and frozen-water storage are strongly affected by variations in surface ... -
Atmospheric Contributions to the Reversal of Surface Temperature Anomalies Between Early and Late Winter Over Eurasia
Xu, Xinping; He, Shengping; Zhou, Botao; Wang, Huijun (Journal article; Peer reviewed, 2022)Observations have shown subseasonal reversal of temperature anomalies between early and late winter over Eurasia, which is distinct from the seasonal mean condition. Based on the reanalysis data, the 1800-year control ... -
Constraining CMIP6 Projections of an Ice-Free Arctic Using a Weighting Scheme
Zhao, Jiazhen; He, Shengping; Wang, Huijun; Li, Fei (Journal article; Peer reviewed, 2022)Employing a model democracy in which each model is equally weighted may lead to a poor estimation of the true uncertainty in climate projections from phase 6 of the Coupled Model Intercomparison Project (CMIP6). The ... -
Contributors to linkage between Arctic warming and East Asian winter climate
Xu, Xinping; He, Shengping; Gao, Yongqi; Zhou, Botao; Wang, Huijun (Journal article; Peer reviewed, 2021)Previous modelling and observational studies have shown discrepancies in the interannual relationship of winter surface air temperature (SAT) between Arctic and East Asia, stimulating the debate about whether Arctic change ... -
Eurasian Cooling Linked to the Vertical Distribution of Arctic Warming
He, Shengping; Xu, Xinping; Furevik, Tore; Gao, Yongqi (Journal article; Peer reviewed, 2020)Observations show that deep Arctic winter warming, extending from surface to mid‐troposphere, has concurred with below‐average temperature over central Eurasia. Modeling studies focusing on the response to Arctic sea ice ... -
The extreme Arctic warm anomaly in November 2020
Fan, Qiyao; Xu, Xinping; He, Shengping; Zhou, Botao (Journal article; Peer reviewed, 2022)In November 2020, the eastern Arctic experienced an extensive extreme warm anomaly (i.e., the second strongest case since 1979), which was followed by extreme cold conditions over East Asia in early winter. The observed ... -
Historical and future runoff changes in the Yangtze River Basin from CMIP6 models constrained by a weighting strategy
Zhao, Jiazhen; He, Shengping; Wang, Huijun (Journal article; Peer reviewed, 2022)Based on the ERA5-Land datasets from 1981–2020, a decadal oscillation has been found in the variation of summer runoff in the middle and lower reaches of the Yangtze River Basin (MLYRB). The oscillation suggests that the ... -
Impact of late spring Siberian snow on summer rainfall in South-Central China
Shen, Haibo; Li, Fei; He, Shengping; Orsolini, Yvan; Li, Jingyi (Journal article; Peer reviewed, 2020)Located in the Yangtze River Valley and surrounded by mountains, South-Central China (SCC) frequently suffered from natural disasters such as torrential precipitation, landslide and debris flow. Here we provide corroborative ... -
Impacts of the autumn Arctic sea ice on the intraseasonal reversal of the winter Siberian high
Lü, Zhuozhuo; He, Shengping; Li, Fei; Wang, Huijun (Peer reviewed; Journal article, 2019-02)During 1979–2015, the intensity of the Siberian high (SH) in November and December–January (DJ) is frequently shown to have an out-of-phase relationship, which is accompanied by opposite surface air temperature and circulation ... -
