    • Assessing the influence of sea surface temperature and arctic sea ice cover on the uncertainty in the boreal winter future climate projections 

      Cheung, Ho-Nam; Keenlyside, Noel Sebastian; Koenigk, Torben; Yang, Shuting; Tian, Tian; Xu, Zhiqing; Gao, Yongqi; Ogawa, Fumiaki; Omrani, Nour-Eddine; Qiao, Shaobo; Zhou, Wen (Journal article; Peer reviewed, 2022)
      We investigate the uncertainty (i.e., inter-model spread) in future projections of the boreal winter climate, based on the forced response of ten models from the CMIP5 following the RCP8.5 scenario. The uncertainty in the ...

    • The Crucial Role of the Subpolar North Atlantic for Skillful Decadal Climate Predictions 

      Drews, Annika; Schmith, Torben; Tian, Tian; Wang, Yiguo; Devilliers, Marion; Keenlyside, Noel Sebastian; Yang, Shuting; Olsen, Steffen M. (Journal article; Peer reviewed, 2024)
      We investigate the role of the subpolar North Atlantic (SPNA) for downstream predictability, using two decadal climate prediction systems. We use the subpolar extreme cold and fresh anomaly event developing in winter ...

    • Impact of Arctic sea ice variations on winter temperature anomalies in northern hemispheric land areas 

      Köenigk, Torben; Gao, Yongqi; Gastineau, Guillaume; Keenlyside, Noel; Nakamura, Tetsu; Ogawa, Fumiaki; Orsolini, Yvan; Semenov, Vladimir A.; Suo, Lingling; Tian, Tian; Wang, Tao; Wettstein, Justin; Yang, Shuting (Peer reviewed; Journal article, 2018-07-30)
      Coordinated numerical ensemble experiments with six different state-of-the-art atmosphere models have been used in order to evaluate the respective impact of the observed Arctic sea ice and sea surface temperature (SST) ...

    • WMO Global Annual to Decadal Climate Update A Prediction for 2021-25 

      Hermanson, Leon; Smith, Doug; Seabrook, Melissa; Bilbao, Roberto; Doblas-Reyes, Francisco; Tourigny, Etienne; Lapin, Vladimir; Kharin, Viatcheslav V.; Merryfield, William J.; Sospedra-Alfonso, Reinel; Athanasiadis, Panos; Nicoli, Dario; Gualdi, Silvio; Dunstone, Nick; Eade, Rosie; Scaife, Adam; Collier, Mark; O'Kane, Terence; Kitsios, Vassili; Sandery, Paul; Pankatz, Klaus; Früh, Barbara; Pohlmann, Holger; Müller, Wolfgang; Kataoka, Takahito; Tatebe, Hiroaki; Ishii, Masayoshi; Imada, Yukiko; Kruschke, Tim; Koenigk, Torben; Karami, Mehdi Pasha; Yang, Shuting; Tian, Tian; Zhang, Liping; Delworth, Tom; Yang, Xiaosong; Zeng, Fanrong; Wang, Yiguo; Counillon, Francois Stephane; Keenlyside, Noel Sebastian; Bethke, Ingo; Lean, Judith; Luterbacher, Jürg; Kolli, Rupa Kumar; Kumar, Arun (Journal article; Peer reviewed, 2022)
      As climate change accelerates, societies and climate-sensitive socioeconomic sectors cannot continue to rely on the past as a guide to possible future climate hazards. Operational decadal predictions offer the potential ...
