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 ... -
Impact of Cyclonic Wind Anomalies Caused by Massive Winter Sea Ice Retreat in the Barents Sea on Atlantic Water Transport Toward the Arctic: A Model Study
Heukamp, Finn Ole; Kanzow, Torsten; Wang, Qiang; Wekerle, Claudia; Gerdes, Rüdiger (Journal of Geophysical Research: Oceans, 2023-03-15)The Arctic is warming much faster than the global average. This is known as Arctic Amplification and is caused by feedbacks in the local climate system. In this study, we explore a previously proposed hypothesis that an ... -
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 ... -
Seasonal and Mesoscale Variability of the Two Atlantic Water Recirculation Pathways in Fram Strait
Hofmann, Zerlina; von Appen, Wilken‐Jon; Wekerle, Claudia (Journal of Geophysical Research: Oceans, 2021-06-25)Atlantic Water (AW), which is transported northward by the West Spitsbergen Current (WSC), partly recirculates (i.e., turns westward) in Fram Strait. This determines how much heat and salt reaches the Arctic Ocean, and how ... -
Simulated Signatures of Greenland Melting in the North Atlantic: A Model Comparison With Argo Floats, Satellite Observations, and Ocean Reanalysis
Stolzenberger, Sophie; Rietbroek, Roelof; Wekerle, Claudia; Uebbing, Bernd; Kusche, Jürgen (Journal of Geophysical Research: Oceans, 2022-11-22)Increased Greenland ice sheet melting has an impact on global mean and regional sea level rise and the ocean circulation. In this study, we explore whether Greenland melting signatures found in ocean model simulations are ...
