Intensification of the Atlantic Water Supply to the Arctic Ocean Through Fram Strait Induced by Arctic Sea Ice Decline
Wang, Qiang; Wekerle, Claudia; Wang, Xuezhu; Danilov, Sergey; Koldunov, Nikolay; Sein, Dmitry; Sidorenko, Dmitry; von Appen, Wilken-Jon; Jung, Thomas (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 Heat Transport Into the Barents Sea: Distinct Controls on the Upward Trend and Interannual Variability
Wang, Qiang; Wang, Xuezhu; Wekerle, Claudia; Danilov, Sergey; Jung, Thomas; Koldunov, Nikolay; Lind, Sigrid; Sein, Dmitry; Shu, Qi; Sidorenko, Dmitry (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, Sergey; Koldunov, Nikolay; Oliver, Marcel; Sidorenko, Dmitry (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 ... -
Sea Ice Rheology Experiment (SIREx): 2. Evaluating Linear Kinematic Features in High‐Resolution Sea Ice Simulations
Hutter, Nils; Bouchat, Amélie; Dupont, Frédéric; Dukhovskoy, Dmitry; Koldunov, Nikolay; Lee, Younjoo J.; Lemieux, Jean‐François; Lique, Camille; Losch, Martin; Maslowski, Wieslaw; Myers, Paul G.; Ólason, Einar; Rampal, Pierre; Rasmussen, Till; Talandier, Claude; Tremblay, Bruno; Wang, Qiang (Journal of Geophysical Research: Oceans, 2022-04-23)Simulating sea ice drift and deformation in the Arctic Ocean is still a challenge because of the multiscale interaction of sea ice floes that compose the Arctic Sea ice cover. The Sea Ice Rheology Experiment (SIREx) is a ... -
The Arctic Ocean in CMIP6 Models: Biases and Projected Changes in Temperature and Salinity
Khosravi, Narges; Wang, Qiang; Koldunov, Nikolay; Hinrichs, Claudia; Semmler, Tido; Danilov, Sergey; Jung, Thomas (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 ...
