AMOC Discrepancies across Reanalyses and Models Limit Dynamical Understanding

The Atlantic meridional overturning circulation (AMOC) influences global climate, yet its multiscale variability and the processes governing it remain uncertain across models and observations. Using four ocean reanalyses and forced ocean–sea ice simulations from three model families [Energy Exascale Earth System Mode...

No longer polar opposites: the Arctic and the Antarctic are converging towards a seasonally dominated sea-ice regime

Over the satellite period, Arctic and Antarctic sea ice extent seemed to follow opposite pathways. Arctic sea ice showed a strong and prolonged decrease until 2007 and then stalled in its rate of decline. Antarctic sea ice extent, on the other hand, displayed a small but significant increase until 2015. After 2015, A...

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

Neptune: An AI model for Global Ocean Subseasonal Prediction

Neptune provides compelling evidence that end-to-end data-driven ocean emulators can become a powerful component of next-generation S2S forecasting systems, emulating ocean state at high spatio-temporal resolution.

CMIP7 data request: ocean and sea ice priorities and opportunities

Abstract. The ocean and sea ice are central to Earth's climate system, influencing global heat and carbon cycles, weather patterns, and sea level rise. Recent decades have seen rapid advances in Earth System Models (ESMs), but limitations remain in simulating and comparing key oceanic and cryospheric processes across m...
