Abstract Arctic cyclones are key drivers of sea ice and ocean variability. During the 2019–2020 Multidisciplinary drifting Observatory for Study Climate (MOSAiC) expedition, joint observations coupled air‐ice‐ocean system were collected at multiple spatial scales. Here, we present a strong mid‐winter cyclone that impacted MOSAiC site as it drifted in central pack ice. The dynamical response showed structure scale evolving translating cyclonic wind field. Internal stress play significant roles, resulting timing offsets between atmospheric forcing post‐cyclone inertial ringing ocean. Ice motion to field then forces upper currents through frictional drag. strongest impacts from passing occur result surface low‐level jet (LLJ) behind trailing cold front changing directions warm‐sector LLJ post cold‐frontal LLJ. Impacts prolonged ice‐ocean response.

Abstract Atmospheric turbulence over the Arctic sea‐ice surface has been understudied due to lack of observational data. In this study, we focus on kinetic energy ( TKE ) sea ice and distinguish its two different vertical structures, “Surface” type “Elevated” type, using observations during Multidisciplinary drifting Observatory for Study Climate expedition (MOSAiC). The maximum near (at 2 m), while at a higher level (6 m). budget analysis indicates that is caused by increased shear production 6 m. addition, spectral reveals contribution horizontal large eddies enhanced in type. Finally, how structure affects parameterization turbulent momentum flux discussed.
