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

Peril matrices detailing relative changes in tropical cyclone parameters under current and future climate regimes. The matrices likely contain fractional changes in annual mean frequency, mean maximum intensity, and mean latitude of genesis. The project is a collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide, hosted by the Australian Ocean Data Network.

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 profiles between current and future climate simulations.
• Incorporating climate change influence into regional disaster risk assessments.

Strengths

• Output is a set of peril matrices, a structured format for risk analysis.
• Analysis incorporates the influence of climate change on tropical cyclone hazard.
• Project represents a multi-organizational collaboration with expertise from DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
