Zonal Wave-3 Impact on Antarctic Ocean and Sea Ice Dynamics

Australian Ocean Data Network hosts data assessing the impact of the Zonal Wave-3 atmospheric mode on the Antarctic Margins. The research used atmospheric perturbations on the ACCESS-OM2 ocean–sea ice model to evaluate the regional impact of the ZW3 mode and its phases on the subpolar Southern Ocean. The dataset was last updated on 2026-04-28.

Use Cases

• Modeling the impact of the Zonal Wave-3 mode on Antarctic sea ice anomalies based on the described atmospheric perturbations.
• Analyzing future changes in Southern Ocean heat flux based on the expectation that the ZW3 mode will become stronger.
• Studying regional ocean responses to different phases of the Zonal Wave-3 mode based on the model setup described.
• Investigating dense water formation processes on the Antarctic margins in relation to atmospheric forcing.

Strengths

• Based on the ACCESS-OM2 ocean–sea ice model, a recognized simulation tool.
• Focuses on the Zonal Wave-3 mode, a first-order atmospheric driver linked to sea ice and heat flux anomalies.
• Last updated on 2026-04-28, indicating recent maintenance.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description mentions PNG and HTML file formats, suggesting the primary data may be visualizations and reports rather than raw model output.
