Short summary
Short summary
This study developed a new assimilation scheme that incorporates a sliding ensemble method and a parallel-friendly computational workflow. The system achieves a 30-fold speedup in the analysis step over the resource-efficient Ensemble Optimal Interpolation approach while improving analysis quality, particularly in eddy-rich regions. The resulting 1–6-day forecasts rank among the best global systems for key ocean variables, offering a scalable and practical solution for ocean prediction.

Short summary
Short summary
We introduce China's first de-aliasing computation platform, incorporating China's Atmospheric Reanalysis and an in-house ocean circulation model. This platform produces CRA-LICOM, a high-frequency atmospheric and oceanic gravity de-aliasing product with a 6-hourly, 50 km resolution covering 2002–2024 globally. This product is reliable for de-aliasing, signal separation in satellite gravity missions, and climate change studies.

Short summary
We propose the concept of mesoscale ocean direct numerical simulation (MODNS), which should resolve the first baroclinic deformation radius and ensure the numerical dissipative effects do not directly contaminate the mesoscale motions. It can be a benchmark for testing mesoscale ocean large eddy simulation (MOLES) methods in ocean models. We build an idealized Southern Ocean model using MITgcm to generate a type of MODNS. We also illustrate the diversity of multiscale eddy interactions.

Increasing resolution improves model skills in simulating the Arctic Ocean, but other factors such as parameterizations and numerics are at least of the same importance for obtaining reliable simulations.

Short summary
The ocean mixed layer is the interface between the ocean interior and the atmosphere and plays a key role in climate variability. We evaluate the performance of the new generation of ocean models for climate studies, designed to resolve
ocean eddies, which are the largest source of ocean variability and modulate the mixed-layer properties. We find that the mixed-layer depth is better represented in eddy-rich models but, unfortunately, not uniformly across the globe and not in all models.

Short summary
We develop an ocean general circulation model based on heterogeneous computing architectures. The model is optimized to address a series of challenges that are particularly crucial for kilometer-scale resolution ocean modeling. We conduct a short-term global simulation test with a horizontal resolution of 2 km. The simulation demonstrates the high capacity of the model to capture the oceanic meso- to submesoscale processes.
