Eddy Kinetic Energy in the Arctic Ocean From a Global Simulation With a 1-km Arctic
Wang, Qiang; Koldunov, Nikolay V.; Danilov, Sergey; Sidorenko, Dmitry; Wekerle, Claudia; Scholz, Patrick; Bashmachnikov, Igor L.; Jung, Thomas (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.; Danilov, Sergey; Sidorenko, Dmitry; Hutter, Nils; Losch, Martin; Goessling, Helge; Rakowsky, Natalja; Scholz, Patrick; Sein, Dmitry; Wang, Qiang; Jung, Thomas (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 ... -
Ocean Model Formulation Influences Transient Climate Response
Semmler, Tido; Jungclaus, Johann; Danek, Christopher; Goessling, Helge F.; Koldunov, Nikolay V.; Rackow, Thomas; Sidorenko, Dmitry (Journal of Geophysical Research: Oceans, 2021-12-05)The transient climate response (TCR) is 20% higher in the Alfred Wegener Institute Climate Model (AWI‐CM) compared to the Max Planck Institute Earth System Model (MPI‐ESM) whereas the equilibrium climate sensitivity (ECS) ...
