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

A collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide produced peril matrices detailing relative changes in tropical cyclone parameters. The matrices evaluate fractional changes in parameters like annual mean frequency and mean maximum intensity between current and future climate GCM simulations. This assessment extends previous risk models by incorporating climate change influences on cyclone hazard.

Use Cases

• Modeling financial risk to infrastructure based on projected changes in cyclone frequency and intensity.
• Assessing agricultural vulnerability based on shifts in the mean latitude of cyclone genesis.
• Comparing tropical cyclone hazard under current and future climate regimes using GCM simulation outputs.

Strengths

• Produced by a collaboration of four specialized organizations: DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide.
• Extends previous risk assessments by explicitly incorporating the influence of climate change on tropical cyclone hazard.
• Output includes peril matrices detailing multiple key parameters, such as annual mean frequency and mean maximum intensity.

Limitations

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