    • A note on the statistical evidence for an influence of geomagnetic activity on Northern Hemisphere seasonal-mean stratospheric temperatures using the Japanese 55-year Reanalysis 

      Tartaglione, Nazario; Toniazzo, Thomas; Orsolini, Yvan; Otterå, Odd Helge (Peer reviewed; Journal article, 2020)
      We employ JRA-55 (Japanese 55-year Reanalysis), a recent second-generation global reanalysis providing data of high quality in the stratosphere, to examine whether a distinguishable effect of geomagnetic activity on Northern ...

    • Impact of solar irradiance and geomagnetic activity on polar NOx, ozone and temperature in WACCM simulations 

      Tartaglione, Nazario; Toniazzo, Thomas; Orsolini, Yvan J.; Otterå, Odd Helge (Peer reviewed; Journal article, 2020)
      The response of the atmosphere to solar irradiance and geomagnetic activity is analyzed in experiments with the Whole Atmosphere Community Climate Model (WACCM) under idealized forcings. Four experiments are carried out ...

    • Overview of the Norwegian Earth System Model (NorESM2) and key climate response of CMIP6 DECK, historical, and scenario simulations 

      Seland, Øyvind; Bentsen, Mats; Oliviè, Dirk Jan Leo; Toniazzo, Thomas; Gjermundsen, Ada; Graff, Lise Seland; Debernard, Jens Boldingh; Gupta, Alok Kumar; He, Yan-Chun; Kirkevåg, Alf; Schwinger, Jörg; Tjiputra, Jerry; Aas, Kjetil Schanke; Bethke, Ingo; Fan, Yuanchao; Griesfeller, Jan; Grini, Alf; Guo, Chuncheng; Ilicak, Mehmet; Karset, Inger Helene H.; Landgren, Oskar Andreas; Liakka, Johan; Moseid, Kine Onsum; Nummelin, Aleksi; Spensberger, Clemens; Tang, Hui; Zhang, Zhongshi; Heinze, Christoph; Iversen, Trond; Schulz, Michael (Peer reviewed; Journal article, 2020)
      The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 is based on the second version of the Community Earth System Model (CESM2) and shares with CESM2 the computer ...

    • Reconciling and Improving Formulations for Thermodynamics and Conservation Principles in Earth System Models (ESMs) 

      Lauritzen, P.H.; Kevlahan, N.K.-R.; Toniazzo, Thomas; Eldred, C.; Dubos, T.; Gassmann, A.; Larson, V.E.; Jablonowski, C.; Guba, O.; Shipway, B.; Harrop, B.E.; Lemarié, F.; Tailleux, R.; Herrington, A.R.; Large, W.; Rasch, P.J.; Donahue, A.S.; Wan, H.; Conley, A.; Bacmeister, J.T. (Peer reviewed; Journal article, 2022)
      Earth System Models (ESMs) have numerous total energy budget errors. This article establishes the governing total energy equations for large-scale ESMs and assesses the energy budget errors in real-world simulations in a ...

    • 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 (Peer reviewed; Journal article, 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 ...

    • 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 (Peer reviewed; Journal article, 2019)
      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 ...
