• The 11 year solar cycle UV irradiance effect and its dependency on the Pacific Decadal Oscillation 

      Guttu, Sigmund; Orsolini, Yvan J.; Stordal, Frode; Otterå, Odd Helge; Omrani, Nour-Eddine (Journal article; Peer reviewed, 2021)
      The stratospheric, tropospheric and surface impacts from the 11 year ultraviolet solar spectral irradiance (SSI) variability have been extensively studied using climate models and observations. Here, we demonstrate using ...
    • 2020/21 record-breaking cold waves in east of China enhanced by the ‘Warm Arctic-Cold Siberia’ pattern 

      Zhang, Yijia; Yin, Zhicong; Wang, Huijun; He, Shengping (Journal article; Peer reviewed, 2021)
      Extreme cold waves frequently occur in east of China that dramatically endanger ecological agriculture, power infrastructure and human life. In this study, we found that the 'Warm Arctic-Cold Siberia' pattern (WACS) ...
    • Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation 

      Beghoura, Houda; Gorgues, Thomas; Fransner, Sara Filippa Krusmynta; Auger, Pierre-Amaël; Memery, Laurent (Journal article; Peer reviewed, 2023)
      Studies assessing potential measures to counteract the marine deoxygenation attributed to anthropogenic activities have been conducted in a few coastal environments and at regional scale, but not yet on a global scale. One ...
    • Historical and future runoff changes in the Yangtze River Basin from CMIP6 models constrained by a weighting strategy 

      Zhao, Jiazhen; He, Shengping; Wang, Huijun (Journal article; Peer reviewed, 2022)
      Based on the ERA5-Land datasets from 1981–2020, a decadal oscillation has been found in the variation of summer runoff in the middle and lower reaches of the Yangtze River Basin (MLYRB). The oscillation suggests that the ...
    • Indicators and trends of polar cold airmass 

      Kanno, Yuki; Walsh, John E.; Abdillah, Muhammad R; Yamaguchi, Junpei; Iwasaki, Toshiki (Journal article; Peer reviewed, 2019)
      Trends and variations in the amount of cold airmass in the Arctic and the Northern Hemisphere are evaluated for the 60 year period, 1959–2018. The two indicators are (1) polar cold air mass (PCAM), which is the amount of ...
    • Multidecadal variability of ENSO in a recharge oscillator framework 

      Rodriguez Crespo, Lander; Rodríguez-Fonseca, María Belén; Polo, Irene; Keenlyside, Noel Sebastian; Dommenget, Dietmar (Journal article; Peer reviewed, 2022)
      We use a conceptual recharge oscillator model to identify changes in El Niño and the Southern Oscillation (ENSO) statistics and dynamics during the observational record. The variability of ENSO has increased during the ...
    • 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 ...
    • Subsea permafrost carbon stocks and climate change sensitivity estimated by expert assessment 

      Sayedi, Sayedeh Sara; Abbott, Benjamin W.; Thornton, Brett F.; Frederick, Jennifer M.; Vonk, Jorien E.; Overduin, Paul; Schädel, Christina; Schuur, Edward A.G.; Bourbonnais, Annie; Demidov, Nikita; Gavrilov, Anatoly; He, Shengping; Hugelius, Gustaf; Jakobsson, Martin; Jones, Miriam C.; Joung, DongJoo; Kraev, Gleb; Macdonald, Robie W.; McGuire, A. David; Mu, Cuicui; O'Regan, Matt; Schreiner, Kathryn M.; Stranne, Christian; Pizhankova, Elena; Vasiliev, Alexander; Westermann, Sebastian; Zarnetske, Jay P.; Zhang, Tingjun; Ghandehari, Mehran; Baeumler, Sarah; Brown, Brian C.; Frei, Rebecca J. (Journal article; Peer reviewed, 2020)
      The continental shelves of the Arctic Ocean and surrounding seas contain large stocks of organic matter (OM) and methane (CH4), representing a potential ecosystem feedback to climate change not included in international ...
