    • Impact of ocean and sea ice initialisation on seasonal prediction skill in the Arctic 

      Kimmritz, Madlen; Counillon, Francois; Smedsrud, Lars H.; Bethke, Ingo; Keenlyside, Noel; Ogawa, Fumiaki; Wang, Yiguo (Peer reviewed; Journal article, 2019)
      There is a growing demand for skillful prediction systems in the Arctic. Using the Norwegian Climate Prediction Model (NorCPM) that combines the fully-coupled Norwegian Earth System Model and the Ensemble Kalman filter, ...
    • Impact of Snow Initialization in Subseasonal‐to‐Seasonal Winter Forecasts With the Norwegian Climate Prediction Model 

      Li, Fei; Orsolini, Yvan; Keenlyside, Noel; Shen, Mao-Lin; Counillon, Francois; Wang, Yiguo (Peer reviewed; Journal article, 2019)
      Snow initialization has been previously investigated as a potential source of predictability atthe subseasonal‐to‐seasonal (S2S) timescale in winter and spring, through its local radiative,thermodynamical, and hydrological ...
    • Relating model bias and prediction skill in the equatorial Atlantic 

      Counillon, Francois; Keenlyside, Noel; Toniazzo, Thomas; Koseki, Shunya; Demissie, Teferi Dejene; Bethke, Ingo; Wang, Yiguo (Journal article; Peer reviewed, 2021)
      We investigate the impact of large climatological biases in the tropical Atlantic on reanalysis and seasonal prediction performance using the Norwegian Climate Prediction Model (NorCPM) in a standard and an anomaly coupled ...
    • Seasonal predictions initialised by assimilating sea surface temperature observations with the EnKF 

      Wang, Yiguo; Counillon, Francois; Keenlyside, Noel; Svendsen, Lea; Gleixner, Stephanie; Kimmritz, Madlen; Dai, Panxi; Gao, Yongqi (Peer reviewed; Journal article, 2019-07-23)
      This study demonstrates that assimilating SST with an advanced data assimilation method yields prediction skill level with the best state-of-the-art systems. We employ the Norwegian Climate Prediction Model (NorCPM)—a ...
