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 ... -
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 ... -
Influence of solar wind energy flux on the interannual variability of ENSO in the subsequent year
He, Shengping; Wang, Hui-Jun; Gao, Yongqi; Li, Fei; Li, Hui; Wang, Chi (Peer reviewed; Journal article, 2018)Previous studies have tended to adopt the quasi-decadal variability of the solar cycle (e.g. sunspot number (SSN) or solar radio flux at 10.7 cm (F10.7) to investigate the effect of solar activity on El Niño–Southern ... -
Intensified Impacts of Central Pacific ENSO on the Reversal of December and January Surface Air Temperature Anomaly over China since 1997
Li, Hua; Fan, Ke; He, Shengping; Liu, Yong; Yuan, Xing; Wang, Huijun (Journal article; Peer reviewed, 2021)The reversal of surface air temperature anomalies (SATA) in winter brings a great challenge for short-term climate prediction, and the mechanisms are not well understood. This study found that the reversal of SATA between ... -
