• Eddy Kinetic Energy in the Arctic Ocean From a Global Simulation With a 1-km Arctic 

      Wang, QiangORCIDiD; Koldunov, Nikolay V.ORCIDiD; Danilov, SergeyORCIDiD; Sidorenko, DmitryORCIDiD; Wekerle, ClaudiaORCIDiD; Scholz, PatrickORCIDiD; Bashmachnikov, Igor L.ORCIDiD; Jung, ThomasORCIDiD (Geophysical Research Letters, 2020)
      Simulating Arctic Ocean mesoscale eddies in ocean circulation models presents a great challenge because of their small size. This study employs an unstructured-mesh ocean-sea ice model to conduct a decadal-scale global ...
    • Fast EVP Solutions in a High-Resolution Sea Ice Model 

      Koldunov, Nikolay V.ORCIDiD; Danilov, SergeyORCIDiD; Sidorenko, DmitryORCIDiD; Hutter, NilsORCIDiD; Losch, MartinORCIDiD; Goessling, HelgeORCIDiD; Rakowsky, NataljaORCIDiD; Scholz, PatrickORCIDiD; Sein, DmitryORCIDiD; Wang, QiangORCIDiD; Jung, ThomasORCIDiD (Journal of Advances in Modeling Earth Systems, 2019)
      Sea ice dynamics determine the drift and deformation of sea ice. Nonlinear physics, usually expressed in a viscous-plastic rheology, makes the sea ice momentum equations notoriously difficult to solve. At increasing sea ...
    • Intensification of the Atlantic Water Supply to the Arctic Ocean Through Fram Strait Induced by Arctic Sea Ice Decline 

      Wang, QiangORCIDiD; Wekerle, ClaudiaORCIDiD; Wang, XuezhuORCIDiD; Danilov, SergeyORCIDiD; Koldunov, NikolayORCIDiD; Sein, DmitryORCIDiD; Sidorenko, DmitryORCIDiD; von Appen, Wilken-JonORCIDiD; Jung, ThomasORCIDiD (Geophysical Research Letters, 2020)
      Substantial changes have occurred in the Arctic Ocean in the last decades. Not only sea ice has retreated significantly, but also the ocean at middepth showed a warming tendency. By using simulations we identified a mechanism ...
    • Ocean Bottom Pressure Variability: Can It Be Reliably Modeled? 

      Androsov, Alexey; Boebel, Olaf; Schröter, JensORCIDiD; Danilov, SergeyORCIDiD; Macrander, Andreas; Ivanciu, IoanaORCIDiD (Journal of Geophysical Research: Oceans, 2020)
      Ocean bottom pressure (OBP) variability serves as a proxy of ocean mass variability, the knowledge of which is needed in geophysical applications. The question of how well it can be modeled by the present general ocean ...
    • Ocean Heat Transport Into the Barents Sea: Distinct Controls on the Upward Trend and Interannual Variability 

      Wang, QiangORCIDiD; Wang, XuezhuORCIDiD; Wekerle, ClaudiaORCIDiD; Danilov, SergeyORCIDiD; Jung, ThomasORCIDiD; Koldunov, NikolayORCIDiD; Lind, SigridORCIDiD; Sein, DmitryORCIDiD; Shu, QiORCIDiD; Sidorenko, DmitryORCIDiD (Geophysical Research Letters, 2019)
      Ocean heat transport through the Barents Sea Opening (BSO) has strong impacts on the Barents Sea ice extent and the climate. In this paper we quantified the contributions from different atmospheric forcing components to ...
    • Ocean Kinetic Energy Backscatter Parametrization on Unstructured Grids: Impact on Global Eddy-Permitting Simulations 

      Juricke, Stephan; Danilov, SergeyORCIDiD; Koldunov, NikolayORCIDiD; Oliver, Marcel; Sidorenko, DmitryORCIDiD (Journal of Advances in Modeling Earth Systems, 2020)
      In this study we demonstrate the potential of a kinetic energy backscatter scheme for use in global ocean simulations. Ocean models commonly employ (bi)harmonic eddy viscosities causing excessive dissipation of kinetic ...
    • The Arctic Ocean in CMIP6 Models: Biases and Projected Changes in Temperature and Salinity 

      Khosravi, NargesORCIDiD; Wang, QiangORCIDiD; Koldunov, NikolayORCIDiD; Hinrichs, ClaudiaORCIDiD; Semmler, TidoORCIDiD; Danilov, SergeyORCIDiD; Jung, ThomasORCIDiD (Earth's Future, 2022-02-11)
      We examine the historical evolution and projected changes in the hydrography of the deep basin of the Arctic Ocean in 23 climate models participating in the Coupled Model Intercomparison Project Phase 6 (CMIP6). The ...
