    • Comparing wavelet and Fourier perspectives on the decomposition of meridional energy transport into synoptic and planetary components 

      Heiskanen, Tuomas Ilkka Henrikki; Graversen, Rune Grand; Rydsaa, Johanne Hope; Isachsen, Pål Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-04)
      The Arctic region shows some of the world's most significant signs of climate change; for instance, a negative trend in summer sea‐ice cover of around 15% per decade and Arctic amplified surface‐air warming that is three times the global average. The atmospheric energy transport plays an important role in the Arctic climate. Recently a Fourier‐based method for studying the atmospheric energy transport ...

    • Direct and indirect impacts of climate change on wheat yield in the Indo-Gangetic plain in India 

      Daloz, Anne Sophie; Rydsaa, Johanne Hope; Hodnebrog, Øivind; Sillmann, Jana; Oort, Bob Eric Helmuth van; Mohr, Christian Wilhelm; Agrawal, M.; Emberson, L.; Stordal, Frode; Zhang, T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-28)
      The Indo-Gangetic Plain (IGP) is one of the main wheat-production regions in India and the world. With climate change, wheat yields in this region will be affected through changes in temperature and precipitation and decreased water availability for irrigation, raising major concerns for national and international food security. Here we use a regional climate model and a crop model to better understand ...

    • The impact of atmospheric Rossby waves and cyclones on the Arctic sea ice variability 

      Hofsteenge, Marte G.; Graversen, Rune Grand; Rydsaa, Johanne Hope; Rey, Zoé (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-17)
      The Arctic sea-ice extent has strongly declined over recent decades. A large inter-annual variability is superimposed on this negative trend. Previous studies have emphasised a significant warming effect associated with latent energy transport into the Arctic region, in particular due to an enhanced greenhouse effect associated with the convergence of the humidity transport over the Arctic. The ...
