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 ... -
Projecting Wintertime Newly Formed Arctic Sea Ice through Weighting CMIP6 Model Performance and Independence
Zhao, Jiazhen; He, Shengping; Fan, Ke; Wang, Huijun; Li, Fei (Journal article; Peer reviewed, 2024)Precipitous Arctic sea-ice decline and the corresponding increase in Arctic open-water areas in summer months give more space for sea-ice growth in the subsequent cold seasons. Compared to the decline of the entire Arctic ... -
Recent Intensified Influence of the Winter North Pacific Sea Surface Temperature on the Mei-Yu Withdrawal Date
Li, Hua; He, Shengping; Fan, Ke; Liu, Yong; Yuan, Xing (Journal article; Peer reviewed, 2021)The mei-yu withdrawal date (MWD) is a crucial indicator of flood/drought conditions over East Asia. It is characterized by a strong interannual variability, but its underlying mechanism remains unknown. We investigated the ... -
Relative Impacts of Sea Ice Loss and Atmospheric Internal Variability on the Winter Arctic to East Asian Surface Air Temperature Based on Large-Ensemble Simulations with NorESM2
He, Shengping; Drange, Helge; Furevik, Tore; Wang, Hui-Jun; Fan, Ke; Graff, Lise Seland; Orsolini, Yvan Joseph Georges Emile G. (Journal article; Peer reviewed, 2024)To quantify the relative contributions of Arctic sea ice and unforced atmospheric internal variability to the “warm Arctic, cold East Asia” (WACE) teleconnection, this study analyses three sets of large-ensemble simulations ... -
Thermodynamic and dynamic contributions to the abrupt increased winter Arctic sea ice growth since 2008
Yi, Daling Li; Fan, Ke; He, Shengping (Journal article; Peer reviewed, 2024)The area of Arctic winter sea ice growth (WSIG) has expanded dramatically since winter 2008. Yet the thermodynamic and dynamic contributions to the abrupt increase in WSIG remain unclear. Here using an ice concentration ...
