• Impacts of Atlantic multi-decadal variability on the Indo-Pacific and Northern Hemisphere climate 

      Svendsen, Lea (Doctoral thesis, 2016-06-03)
      Earlier studies have shown that Atlantic multi-decadal variability (AMY) can impact climate variability globally. However the instrumental records are short compared to the timescale of AMY, and mechanisms for these impacts ...
    • Marine-based multiproxy reconstruction of Atlantic multidecadal variability 

      Svendsen, Lea; Hetzinger, Steffen; Keenlyside, Noel; Gao, Yongqi (Peer reviewed; Journal article, 2014-02-28)
      Atlantic multidecadal variability (AMV) is known to impact climate globally, and knowledge about the persistence of AMV is important for understanding past and future climate variability, as well as modeling and assessing ...
    • NorCPM1 and its contribution to CMIP6 DCPP 

      Bethke, Ingo; Wang, Yiguo; Counillon, Francois Stephane; Keenlyside, Noel Sebastian; Kimmritz, Madlen; Fransner, Filippa; Samuelsen, Annette; Langehaug, Helene R.; Svendsen, Lea; Chiu, Ping-Gin; Passos, Leilane G.; Bentsen, Mats; Guo, Chuncheng; Gupta, Alok Kumar; Tjiputra, Jerry; Kirkevåg, Alf; Oliviè, Dirk Jan Leo; Seland, Øyvind; Vågane, Julie Solsvik; Fan, Yuanchao; Eldevik, Tor (Journal article; Peer reviewed, 2021)
      The Norwegian Climate Prediction Model version 1 (NorCPM1) is a new research tool for performing climate reanalyses and seasonal-to-decadal climate predictions. It combines the Norwegian Earth System Model version 1 (NorESM1) ...
    • A North-South Contrast of Subsurface Salinity Anomalies in the Northwestern Pacific From 2002 to 2013 

      Yan, Youfang; Svendsen, Lea; Wang, Chunzai; Keenlyside, Noel; Xu, Dazhi (Peer reviewed; Journal article, 2019-03)
      This paper finds a north‐south contrast of subsurface salinity trend during 2002–2013 in the northwestern Pacific. Both Argo float data and long‐term repeat hydrographic measurements along the 137°E section show that ...
    • Pacific contribution to decadal surface temperature trends in the Arctic during the twentieth century 

      Svendsen, Lea; Keenlyside, Noel; Muilwijk, Morven; Bethke, Ingo; Omrani, Nour-Eddine; Gao, Yongqi (Journal article; Peer reviewed, 2021)
      Instrumental records suggest multidecadal variability in Arctic surface temperature throughout the twentieth century. This variability is caused by a combination of external forcing and internal variability, but their ...
    • Pacific contribution to the early twentieth-century warming in the Arctic 

      Svendsen, Lea; Keenlyside, Noel; Bethke, Ingo; Gao, Yongqi; Omrani, Nour-Eddine (Journal article; Peer reviewed, 2018)
      Arctic surface temperature warmed more than twice as fast as global temperature during the early twentieth century, similar to that during the recent global warming. This Arctic warming has been attributed to both external ...
    • 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 ...
