• Advances in understanding and parameterization of small-scalephysical processes in the marine Arctic climate system: a review 

      Vihma, Timo; Pirazzini, R; Fer, Ilker; Renfrew, I.A.; Sedlar, J.; Tjernström, M.; Lüpkes, C.; Nygård, T.; Notz, D.; Weiss, J.; Marsan, D.; Cheng, B.; Birnbaum, G.; Gerland, S; Chechin, D.; Gascard, J.-C. (Peer reviewed; Journal article, 2014-09-10)
      The Arctic climate system includes numerous highly interactive small-scale physical processes in the atmosphere, sea ice, and ocean. During and since the International Polar Year 2007–2009, significant advances have been ...

      Lothon, Marie; Louhou, Fabienne; Pino, David; Couvreux, Fleur; Pardyjak, Erik; Reuder, Joachim; Vilà-Guerau De Arellano, Jordi; Durand, Pierre; Hartogensis, Oscar K.; Legain, Dominique; Augustin, Patrick V.; Gioli, Beniamino; Lenschow, Donald H.; Faloona, Ian C.; Yagüe, Carlos; Alexander, Daniel C.; Angevine, Wayne M.; Bargain, Erwan; Barrié, Joël; Bazile, Eric; Bezombes, Yannick; Blay-Carreras, Estel; Van De Boer, Anneke; Boichard, Jean Luc; Bourdon, Anne; Butet, Alain; Campistron, Bernard A.; De Coster, Olivier; Cuxart, Joan; Dabas, Alain M.; Darbieu, Clara; Deboudt, Karine; Delbarre, Hervé; Derrien, Solène; Flament, Pascal; Fourmentin, Marc; Garai, Anirban; Gibert, Fabien; Graf, Alexander T.; Gröbner, Julian; Guichard, Françoise; Jiménez, Mantonia Antonia; Jonassen, Marius Opsanger; Van Den Kroonenberg, Aline C.; Magliulo, Vincenzo; Martin, Sabrina; Martinez, Daniel; Mastrorillo, Laurence; Moene, Arnold F.; Molinos, Francisco Lendinez; Moulin, Emilie; Pietersen, Henk P.; Piguet, Bruno; Pique, Eric; Román-Cascón, Carlos; Rufin-Soler, Caroline; Saïd, Frédérique; Sastre-Marugán, Mariano; Seity, Yann; Steeneveld, Gert Jan; Toscano, Piero; Traullé, Olivier; Tzanos, Diane; Wacker, Stefan; Wildmann, Norman; Zaldei, Alessandro (Peer reviewed; Journal article, 2014-10-16)
      Due to the major role of the sun in heating the earth's surface, the atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, the period of the day that connects the ...
    • Downslope windstorm in Iceland –WRF/MM5 model comparison 

      Rögnvaldsson, Ólafur; Bao, J. W.; Ágústsson, Hálfdán; Ólafsson, Haraldur (Peer reviewed; Journal article, 2011-01-05)
      A severe windstorm downstream of Mt. Öræfajökull in Southeast Iceland is simulated on a grid of 1 km horizontal resolution by using the PSU/NCAR MM5 model and the Advanced Research WRF model. Both models are run with a ...
    • Large-eddy simulation of radiation fog with comprehensive two-moment bulk microphysics: Impact of different aerosol activation and condensation parameterizations 

      Schwenkel, Johannes; Maronga, Bjørn (Peer reviewed; Journal article, 2019-05-29)
      In this paper we study the influence of the cloud microphysical parameterization, namely the effect of different methods for calculating the supersaturation and aerosol activation, on the structure and life cycle of radiation ...
    • A new interpretative framework for below-cloud effects on stable water isotopes in vapour and rain 

      Graf, Pascal; Wernli, Heini; Pfahl, Stephan; Sodemann, Harald (Peer reviewed; Journal article, 2019-01-22)
      Raindrops interact with water vapour in ambient air while sedimenting from the cloud base to the ground. They constantly exchange water molecules with the environment and, in sub-saturated air, they evaporate partially or ...
    • A new roughness length parameterization accounting for wind-wave (mis)alignment 

      Porchetta, Sara; Temel, Orkun; Munoz-Esparza, Domingo; Reuder, Joachim; Monbaliu, Jaak; Van Beeck, Jeroen; van Lipzig, Nicole (Peer reviewed; Journal article, 2019-05-20)
      Two-way feedback occurs between offshore wind and waves. However, the influence of the waves on the wind profile remains understudied, in particular the momentum transfer between the sea surface and the atmosphere. Previous ...

    • Quantifying the contribution of anthropogenic influence to the East Asian winter monsoon in 1960-2012 

      Hao, Xin; He, Shengping; Wang, Huijun; Han, Tingting (Peer reviewed; Journal article, 2019-08-07)
      The East Asian winter monsoon (EAWM) is greatly influenced by many factors that can be classified as anthropogenic forcing and natural forcing. Here we explore the contribution of anthropogenic influence to the change in ...
