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

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 ... -

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 ... -
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 ... -
Impacts of the extratropical North Pacific on boreal summer Arctic circulation
He, Shengping; Furevik, Tore; Wang, Huijun; Li, Fei; Duan, Mingkeng (Journal article; Peer reviewed, 2023)A distinct characteristic of the Arctic summer atmospheric circulation is the anomalous anticyclonic circulation centered over the Arctic Ocean associated with significant Arctic warming. Previous studies have related the ... -
