• 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 ...
    • Assessment of Atmospheric Reanalyses With Independent Observations in the Weddell Sea, the Antarctic 

      Jonassen, Marius Opsanger; Valisuo, Ilona; Vihma, Timo; Uotila, Petteri; Makshtas, Alexander, P.; Launiainen, Jouko (Peer reviewed; Journal article, 2019)
      Surface layer and upper‐air in situ observations from two research vessel cruises and an ice station in the Weddell Sea from 1992 and 1996 are used to validate four current atmospheric reanalysis products: ERA‐Interim, ...
    • Impact of Assimilation of Radiosonde and UAV Observations from the Southern Ocean in the Polar WRF Model 

      Sun, Qizhen; Vihma, Timo; Jonassen, Marius Opsanger; Zhang, Zhanhai (Journal article; Peer reviewed, 2020)
      Weather forecasting in the Southern Ocean and Antarctica is a challenge above all due to the rarity of observations to be assimilated in numerical weather prediction (NWP) models. As observations are expensive and logistically ...
