Pacific Tropical Cyclone Risk Assessment: Peril Matrices for Current and Future Climate

The Assessment of Tropical Cyclone Risks in the Pacific Region project is a collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide. It delivers peril matrices detailing the relative fractional change in key tropical cyclone parameters, such as annual mean frequency and intensity, between current and future climate GCM simulations. The data was last updated on 2026-03-25.

Use Cases

• Modeling financial risk to buildings and infrastructure based on projected changes in tropical cyclone frequency and intensity.
• Assessing agricultural vulnerability based on shifts in the mean latitude of tropical cyclone genesis.
• Comparing tropical cyclone peril under current and future climate regimes using the provided fractional change matrices.
• Informing climate adaptation strategies for Pacific nations based on the integrated hazard and risk assessment.

Strengths

• Produced by a multi-organizational collaboration including Geoscience Australia and AIR Worldwide, leveraging combined expertise.
• Extends previous risk assessments by explicitly incorporating the influence of climate change on tropical cyclone hazard.
• Output includes peril matrices detailing relative changes in multiple key parameters describing tropical cyclone behavior.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data is delivered in document formats (HTML, PDF, DOCX), which may require extraction for computational analysis.
