• Control of Barents Sea wintertime cyclone variability by large-scale atmospheric flow 

      Madonna, Erica; Hes, Gabriel; Li, Camille; Michel, Clio; Siew, Yu Feng (Journal article; Peer reviewed, 2020)
      Extratropical cyclones transport heat and moisture into the Arctic, which can promote surface warming and sea ice melt. We investigate wintertime cyclone variability in the Barents Sea region to understand what controls ...
    • Dynamical drivers of Greenland blocking in climate models 

      Michel, Clio; Madonna, Erica; Spensberger, Clemens; Li, Camille; Outten, Stephen (Journal article; Peer reviewed, 2021)
      Blocking over Greenland is known to lead to strong surface impacts, such as ice sheet melting, and a change in its future frequency can have important consequences. However, as previous studies demonstrated, climate models ...
    • A dynamical systems characterization of atmospheric jet regimes 

      Messori, Gabriele; Harnik, Nili; Madonna, Erica; Lachmy, Orli; Faranda, Davide (Journal article; Peer reviewed, 2021)
      Atmospheric jet streams are typically separated into primarily “eddy-driven” (or polar-front) jets and primarily “thermally driven” (or subtropical) jets. Some regions also display “merged” jets, resulting from the ...
    • Dynamics of concurrent and sequential Central European and Scandinavian heatwaves 

      Spensberger, Clemens; Madonna, Erica; Boettcher, Maxi; Grams, Christian M.; Papritz, Lukas; Quinting, Julian F.; Rothlisberger, Matthias; Sprenger, Michael; Zschenderlein, Philipp (Journal article; Peer reviewed, 2020)
      In both 2003 and 2018 a heatwave in Scandinavia in July was followed by a heatwave in Central Europe in August. Whereas the transition occurred abruptly in 2003, it was gradual in 2018 with a 12-day period of concurrent ...
    • The link between eddy-driven jet variability and weather regimes in the North Atlantic-European sector 

      Madonna, Erica; Li, Camille; Grams, Christian M; Woollings, Tim (Peer reviewed; Journal article, 2017-10)
      This study reconciles two perspectives on wintertime atmospheric variability in the North Atlantic–European sector: the zonal‐mean framework comprising three preferred locations of the eddy‐driven jet (southern, central, ...
    • Mechanisms of regional winter sea-ice variability in a warming arctic 

      Dörr, Jakob Simon; Årthun, Marius; Eldevik, Tor; Madonna, Erica (Journal article; Peer reviewed, 2021)
      The Arctic winter sea ice cover is in retreat overlaid by large internal variability. Changes to sea ice are driven by exchange of heat, momentum, and freshwater within and between the ocean and the atmosphere. Using a ...
    • Nordic Seas Heat Loss, Atlantic Inflow, and Arctic Sea Ice cover over the last century 

      Smedsrud, Lars Henrik; Muilwijk, Morven; Eldevik, Tor; Årthun, Marius; Brakstad, Ailin; Madonna, Erica; Lauvset, Siv Kari; Spensberger, Clemens; Born, Andreas; Drange, Helge; Jeansson, Emil; Li, Camille; Olsen, Are; Skagseth, Øystein; Slater, Donald; Straneo, Fiammetta; Våge, Kjetil (Journal article; Peer reviewed, 2021)
      Poleward ocean heat transport is a key process in the earth system. We detail and review the northward Atlantic Water (AW) flow, Arctic Ocean heat transport, and heat loss to the atmosphere since 1900 in relation to sea ...
    • Reconstructing winter climate anomalies in the Euro-Atlantic sector using circulation patterns 

      Madonna, Erica; Battisti, David; Li, Camille; White, Rachel H. (Journal article; Peer reviewed, 2021)
      The efficacy of Euro-Atlantic circulation regimes for estimating wintertime climate anomalies (precipitation and surface temperature) over Europe is assessed. A comparison of seasonal climate reconstructions from two ...
    • The relationship between the eddy-driven jet stream and northern European sea level variability 

      Mangini, Fabio; Chafik, Léon; Madonna, Erica; Li, Camille; Bertino, Laurent; Nilsen, Jan Even Øie (Journal article; Peer reviewed, 2021)
      Wintertime sea level variability over the northern European continental shelf is largely wind-driven. Using daily gridded sea level anomaly from altimetry, we examine both the spatial and the temporal relationship between ...
    • Suppressed eddy driving during southward excursions of the North Atlantic jet on synoptic to seasonal time scales 

      Madonna, Erica; Li, Camille; Wettstein, Justin (Peer reviewed; Journal article, 2019-09-05)
      Jet streams shape midlatitude weather and climate. The North Atlantic jet is mainly eddy‐driven, with frequent north–south excursions on synoptic time scales arising from eddy forcings and feedbacks. There are, however, ...
    • Understanding differences in North Atlantic poleward ocean heat transport and its variability in global climate models 

      Madonna, Erica; Sandø, Anne Britt (Journal article; Peer reviewed, 2021)
      The ocean heat transport from the North Atlantic to the Barents Sea impacts the sea ice extent and the energy budget of the Arctic. The analyzed climate models from the fifth (CMIP5) and sixth Coupled Model Intercomparison ...
