• A multimodel examination of climate Extremes in an idealized geoengineering experiment 

      Curry, Charles L.; Sillmann, Jana; Bronaugh, David; Alterskjær, Kari; Cole, Jason N.S.; Ji, Duoying; Kravitz, Ben; Kristjansson, Jon Egill; Moore, John C.; Muri, Helene Østlie; Niemeier, Ulrike; Robock, Alan; Tilmes, Simone; Yang, Shuting (Peer reviewed; Journal article, 2014)
      Temperature and precipitation extremes are examined in the Geoengineering Model Intercomparison Project experiment G1, wherein an instantaneous quadrupling of CO2 from its preindustrial control value is offset by a ...
    • Downscaling probability of long heatwaves based on seasonal mean daily maximum temperatures 

      Benestad, Rasmus; van Oort, Bob; Justino, Flavio; Stordal, Frode; Parding, Kajsa; Mezghani, Abdelkader; Erlandsen, Helene B.; Sillmann, Jana; Pereira-Flores, Milton E (Peer reviewed; Journal article, 2018)
      A methodology for estimating and downscaling the probability associated with the duration of heatwaves is presented and applied as a case study for Indian wheat crops. These probability estimates make use of empirical-statistical ...
    • Local biomass burning is a dominant cause of the observed precipitation reduction in southern Africa 

      Hodnebrog, Øivind; Myhre, Gunnar; Forster, Piers M.; Sillmann, Jana; Samset, Bjørn Hallvard (Peer reviewed; Journal article, 2016)
      Observations indicate a precipitation decline over large parts of southern Africa since the 1950s. Concurrently, atmospheric concentrations of greenhouse gases and aerosols have increased due to anthropogenic activities. ...
    • Observed and simulated temperature extremes during the recent warming hiatus 

      Sillmann, Jana; Donat, M. G.; Fyfe, J. C.; Zwiers, F. W. (Journal article; Peer reviewed, 2014)
      The discrepancy between recent observed and simulated trends in global mean surface temperature has provoked a debate about possible causes and implications for future climate change projections. However, little has been ...
    • Percentile indices for assessing changes in heavy precipitation events 

      Schaer, Christoph; Ban, Nikolina; Fischer, Erich M.; Rajczak, Jan; Schmidli, Juerg; Frei, Christoph; Giorgi, Filippo; Karl, Thomas R.; Kendon, Elisabeth J.; Klein Tank, Albert M. G.; O'Gorman, Paul A.; Sillmann, Jana; Zhang, Xuebin; Zwiers, Francis W. (Journal article; Peer reviewed, 2016)
      Many climate studies assess trends and projections in heavy precipitation events using precipitation percentile (or quantile) indices. Here we investigate three different percentile indices that are commonly used. We ...
    • Synoptic and meteorological drivers of extreme ozone concentrations over Europe 

      Otero, Noelia; Sillmann, Jana; Schnell, Jordan; Rust, Henning W.; Butler, Tim (Journal article; Peer reviewed, 2016)
      The present work assesses the relationship between local and synoptic meteorological conditions and surface ozone concentration over Europe in spring and summer months, during the period 1998–2012 using a new interpolated ...
    • The influence of atmospheric blocking on extreme winter minimum temperatures in North America 

      Whan, Kirien; Zwiers, Francis W.; Sillmann, Jana (Journal article; Peer reviewed, 2016)
      Regional climate models (RCMs) are the primary source of high-resolution climate projections, and it is of crucial importance to evaluate their ability to simulate extreme events under current climate conditions. Many ...
    • Top ten European heatwaves since 1950 and their occurrence in the coming decades 

      Russo, Simone; Sillmann, Jana; Fischer, Erich M. (Journal article; Peer reviewed, 2015)
      The Russian heatwave in 2010 killed tens of thousands of people, and was by far the worst event in Europe since at least 1950, according to recent studies and a novel universal heatwave index capturing both the duration ...
