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 relative changes in tropical cyclone parameters like annual mean frequency, intensity, and genesis latitude between current and future climate simulations. The dataset is hosted by the Australian Ocean Data Network.

Use Cases

• Modeling financial risk to infrastructure based on projected changes in tropical cyclone frequency.
• Assessing agricultural vulnerability based on shifts in tropical cyclone intensity.
• Evaluating regional climate adaptation strategies based on changes in the mean latitude of cyclone genesis.
• Comparing hazard exposure under current and future climate regimes based on peril matrices.

Strengths

• Project is a collaboration between multiple expert organizations: DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide.
• Extends previous risk assessments by incorporating the influence of climate change on tropical cyclone hazard.
• Outputs are 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 may reflect geographic bias inherent to the Pacific region focus.
