    • Mitigating climate biases in the midlatitude North Atlantic by increasing model resolution: SST gradients and their relation to blocking and the jet 

      Athanasiadis, Panos J.; Ogawa, Fumiaki; Omrani, Nour-Eddine; Keenlyside, Noel Sebastian; Schiemann, Reinhard; Baker, Alexander J.; Vidale, Pier Luigi; Bellucci, Alessio; Ruggieri, Paolo; Haarsma, Rein; Roberts, Malcolm J.; Roberts, Chris; Novak, Lenka; Gualdi, Silvio (Journal article; Peer reviewed, 2022)
      Starting to resolve the oceanic mesoscale in climate models is a step change in model fidelity. This study examines how certain obstinate biases in the midlatitude North Atlantic respond to increasing resolution (from 1° ...

    • Pacific circulation response to eastern Arctic sea ice reduction in seasonal forecast simulations 

      Seidenglanz, Anne; Athanasiadis, Panos J.; Ruggieri, Paolo; Cvijanovic, Ivana; Li, Camille; Gualdi, Silvio (Journal article; Peer reviewed, 2021)
      Recent studies point to the sensitivity of mid-latitude winter climate to Arctic sea ice variability. However, there remain contradictory results in terms of character and timing of Northern Hemisphere large-scale circulation ...

    • Propagation of Thermohaline Anomalies and their predictive potential along the Atlantic water pathway 

      Langehaug, Helene R.; Ortega, Pablo; Counillon, Francois Stephane; Matei, Daniela; Maroon, Elizabeth A.; Keenlyside, Noel Sebastian; Mignot, Juliette; Wang, Yiguo; Swingedouw, Didier; Bethke, Ingo; Yang, Shuting; Danabasoglu, Gokhan; Bellucci, Alessio; Ruggieri, Paolo; Nicoli, D.; Årthun, Marius (Journal article; Peer reviewed, 2022)
      We assess to what extent seven state-of-the-art dynamical prediction systems can retrospectively predict winter sea surface temperature (SST) in the subpolar North Atlantic and the Nordic seas in the period 1970–2005. We ...
