Pacific Tropical Cyclone Risk Assessment: Parameter Changes Under Climate Scenarios

Peril matrices detailing relative changes in tropical cyclone parameters under current and future climate regimes. The output is from a collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide, extending previous risk assessments by incorporating climate change influence. The relative changes are evaluated as fractional differences between current and future climate GCM simulations for parameters like frequency, intensity, and genesis latitude.

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 hazard profiles between current and future climate regimes for regional planning.

Strengths

• Produced by a multi-organizational collaboration including Geoscience Australia and AIR Worldwide.
• Extends previous risk assessments by explicitly incorporating climate change influence on cyclone hazard.
• Outputs are structured as peril matrices detailing relative changes in key parameters.

Limitations

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