    • Causes of the large warm bias in the Angola–Benguela Frontal Zone in the Norwegian Earth System Model 

      Koseki, Shunya; Keenlyside, Noel; Demissie, Teferi Dejene; Toniazzo, Thomas; Counillon, Francois; Bethke, Ingo; Ilicak, Mehmet; Shen, Mao-Lin (Journal article; Peer reviewed, 2018)
      We have investigated the causes of the sea surface temperature (SST) bias in the Angola–Benguela Frontal Zone (ABFZ) of the southeastern Atlantic Ocean simulated by the Norwegian Earth System Model (NorESM). Similar to ...

    • 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 ...

      Brändström, B. Urban E.; Enell, Carl-Fredrik; Widell, Ola; Hansson, Thord; Whiter, Daniel; Mäkinen, Sanna; Mikhaylova, Daria; Axelsson, Katarina; Sigernes, Fred; Gulbrandsen, Njål; Schlatter, Nicola M.; Gjendem, Amund Gjerde; Cai, L.; Reistad, Jone Peter; Daae, Marianne; Demissie, Teferi Dejene; Andalsvik, Yngvild Linnea; Roberts, Owen; Poluyanov, Stepan Viktorovich; Chernouss, Sergey (Peer reviewed; Journal article, 2012-05-03)
      Following the 38th Annual European Meeting on Atmospheric Studies by Optical Methods in Siuntio in Finland, an intercalibration workshop for optical low light calibration sources was held in Sodankylä, Finland. The main ...

    • Role of wind stress in driving SST biases in the tropical Atlantic 

      Voldoire, Aurore; Exarchou, Eleftheria; Sánchez-Gómez, Emilia; Demissie, Teferi Dejene; Deppenmeier, Anna-Lena; Frauen, Claudia; Goubanova, Katarina; Hazeleger, Wilco; Keenlyside, Noel; Koseki, Shunya; Prodhomme, Chloé; Shonk, Jonathan; Toniazzo, Thomas; Traoré, Abdoul-Khadre (Journal article; Peer reviewed, 2019-03-13)
      Coupled climate models used for long-term future climate projections and seasonal or decadal predictions share a systematic and persistent warm sea surface temperature (SST) bias in the tropical Atlantic. This study attempts ...

    • Seasonal predictability of Kiremt rainfall in coupled general circulation models 

      Gleixner, Stephanie Nikola; Keenlyside, Noel; Demissie, Teferi Dejene; Counillon, Francois; Wang, Yiguo; Viste, Ellen (Journal article; Peer reviewed, 2017)
      The Ethiopian economy and population is strongly dependent on rainfall. Operational seasonal predictions for the main rainy season (Kiremt, June–September) are based on statistical approaches with Pacific sea surface ...
