Pacific Tropical Cyclone Risk Assessment with Climate Change Parameters

The Assessment of Tropical Cyclone Risks in the Pacific Region project represents a collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide. It delivers peril matrices detailing the relative fractional change in tropical cyclone parameters, such as annual mean frequency and mean maximum intensity, between current and future climate GCM simulations. The dataset was last updated on 2026-04-10.

Use Cases

• Modeling financial risk to assets based on projected changes in tropical cyclone frequency and intensity.
• Assessing climate change impacts on hazard profiles using peril matrices of relative parameter changes.
• Comparing tropical cyclone genesis and behavior between current and future climate model simulations.

Strengths

• Project is a multi-organizational collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide.
• Extends previous risk assessments by incorporating the influence of climate change on tropical cyclone hazard.
• Output includes peril matrices detailing relative changes to specific tropical cyclone parameters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Pacific region focus.
