Increased horizontal resolution provides limited benefits for simulated Arctic and Antarctic sea ice climatology and recent extremes in a NEMO4-SI3 hierarchy

Historical Climate and Future Projection in the North Atlantic and Arctic: Insights from EC-Earth3 High-Resolution Simulations

Abstract. This study presents a new set of high-resolution global climate simulations conducted with the EC-Earth3 model, including a 350 year pre-industrial, followed by historical (1850–2014) and future (2015–2100, SSP2-4.5) simulations. The model features a horizontal resolution of ∼ 40 km in the atmosphere and 0.25...

Contrasting sea ice thickness variability in Arctic pack ice and marginal ice zone through ocean–sea-ice reanalyses

Southern Hemisphere sea ice response to different flow regimes over the Antarctic Peninsula

Low-level winds over Antarctica are overwhelmingly controlled by the local orography. They, in turn, exert a large control over sea ice formation and transport. In this work, we investigate the relationship between Antarctic sea ice and the parameterized orographic gravity wave drag in the UK CMIP6 (Coupled Model Inter...

High-resolution Antarctic sea-ice thickness and snow depth from drift-aware multi-mission altimetry

Borey: A High-Resolution Regional Atmosphere–Ocean–Sea Ice–Wave Hindcast Dataset for the Barents and Kara Seas, 2019–2023

Impact of data assimilation on Arctic sea‐ice thickness variability and its coupling with atmospheric forcing

Sea‐ice thickness (SIT) is a key state variable of the Arctic climate system, yet its representation in coupled ice–ocean models remains uncertain due to sparse observations and complex coupling with atmospheric forcing. Satellite‐based observations have improved the accuracy of SIT in models significantly through data...
