    • Asymmetries in Circulation Anomalies Related to the Phases of the North Atlantic Oscillation on Synoptic Time Scales 

      Schmith, T.; Olsen, S.M.; Yang, S.; Christensen, Jens Hesselbjerg (Peer reviewed; Journal article, 2022)
      The North Atlantic Oscillation (NAO) index is often characterized by independent positive and negative NAO events with a characteristic spatial pattern and a typical lifetime of around 1 week. These events are separated ...

    • Characteristics of precipitation extremes over the Nordic region: added value of convection-permitting modeling 

      Médus, Erika; Thomassen, Emma D.; Belušić, Danijel; Lind, Petter; Berg, Peter; Christensen, Jens Hesselbjerg; Christensen, Ole B.; Dobler, Andreas; Kjellström, Erik; Olsson, Jonas; Yang, Wei (Peer reviewed; Journal article, 2022)
      It is well established that using kilometer scale grid resolution for simulations of weather systems in weather and climate models enhances their realism. This study explores heavy- and extreme-precipitation characteristics ...

    • Climate change information over Fenno-Scandinavia produced with a convection-permitting climate model 

      Lind, Petter; Belušić, Danijel; Médus, Erika; Dobler, Andreas; Pedersen, Rasmus A.; Wang, Fuxing; Matte, Dominic; Kjellström, Erik; Landgren, Oskar Andreas; Lindstedt, David; Christensen, Ole B.; Christensen, Jens Hesselbjerg (Peer reviewed; Journal article, 2022)
      This paper presents results from high-resolution climate change simulations that permit convection and resolve mesoscale orography at 3-km grid spacing over Fenno-Scandinavia using the HARMONIE-Climate (HCLIM) model. Two ...

    • The emergence of projected scaled patterns of extreme temperatures over Europe 

      Ozturk, Tugba; Canbaz, Emine; Bilgin, Başak; Matte, Dominic; Kurnaz, M. Levent; Christensen, Jens Hesselbjerg (Journal article; Peer reviewed, 2023)
      This work investigates the scalability of extreme temperatures over the European domain with global warming levels. We have used the EURO-CORDEX ensemble of regional model simulations at 0.11° resolution for daily minimum ...

    • The future of tundra carbon storage in Greenland – Sensitivity to climate and plant trait changes 

      López-Blanco, Efrén; Langen, Peter L.; Williams, Mathew; Christensen, Jens Hesselbjerg; Boberg, Fredrik; Langley, Kirsty; Christensen, Torben Røjle (Peer reviewed; Journal article, 2022)
      The continuous change in observed key indicators such as increasing nitrogen deposition, temperatures and precipitation will have marked but uncertain consequences for the ecosystem carbon (C) sink-source functioning of ...

    • Future projections of wind energy potentials in the arctic for the 21st century under the RCP8.5 scenario from regional climate models (Arctic-CORDEX) 

      Akperov, Mirseid; Eliseev, Alexey V.; Rinke, Annette; Mokhov, Igor I.; Semenov, Vladimir A.; Dembitskaya, Mariya; Matthes, Heidrun; Adakudlu, Muralidhar; Boberg, Fredrik; Christensen, Jens Hesselbjerg; Dethloff, Klaus; Fettweis, Xavier; Gutjahr, Oliver; Heinemann, Günther; Koenigk, Torben; Sein, Dmitry; Laprise, René; Mottram, Ruth; Nikiéma, Oumarou; Sobolowski, Stefan Pieter; Winger, Katja; Zhang, Wenxin (Peer reviewed; Journal article, 2023)
      The Arctic has warmed more than twice the rate of the entire globe. To quantify possible climate change effects, we calculate wind energy potentials from a multi-model ensemble of Arctic-CORDEX. For this, we analyze future ...

    • Global exposure of population and land-use to meteorological droughts under different warming levels and SSPs: A CORDEX-based study 

      Spinoni, Jonathan; Barbosa, Paulo; Bucchignani, Edoardo; Cassano, John; Cavazos, Tereza; Cescatti, Alessandro; Christensen, Jens Hesselbjerg; Christensen, Ole Bøssing; Coppola, Erika; Evans, Jason P.; Forzieri, Giovanni; Geyer, Beate; Giorgi, Filippo; Jacob, Daniela; Katzfey, Jack; Koenigk, Torben; Laprise, René; Lennard, Christopher; Kurnaz, M. Levent; Li, Delei; Llopart, Marta; McCormick, Niall; Naumann, Gustavo; Nikulin, Grigory; Ozturk, Tugba; Panitz, Hans-Jürgen; da Rocha, Rosmeri Porfirio; Solman, Silvina A.; Syktus, Jozef; Tangang, Fredolin; Teichmann, Claas; Vautard, Robert; Vogt, Jürgen V.; Winger, Katja; Zittis, George; Dosio, Alessandro (Peer reviewed; Journal article, 2021)
      Global warming is likely to cause a progressive drought increase in some regions, but how population and natural resources will be affected is still underexplored. This study focuses on global population, forests, croplands ...

    • Identifying robust bias adjustment methods for European extreme precipitation in a multi-model pseudo-reality setting 

      Schmith, Torben; Thejll, Peter; Berg, Peter; Boberg, Fredrik; Bøssing Christensen, Ole; Christiansen, Bo; Christensen, Jens Hesselbjerg; Sloth Madsen, Marianne; Steger, Christian (Peer reviewed; Journal article, 2021)
      Severe precipitation events occur rarely and are often localised in space and of short duration, but they are important for societal managing of infrastructure. Therefore, there is a demand for estimating future changes ...

    • On the Potentials and Limitations of Attributing a Small-Scale Climate Event 

      Matte, Dominic; Christensen, Jens Hesselbjerg; Feddersen, Henrik; Vedel, Henrik; Nielsen, Niels Woetmann; Pedersen, Rasmus A.; Zeitzen, Rune M. K. (Peer reviewed; Journal article, 2022)
      Intense convective storms can be hazardous when occurring over large populated cities. In a changing climate, decision makers and the general public increasingly need to be able to better understand if and to what extent ...
