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

A 2026 collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide produced peril matrices assessing tropical cyclone financial risk. The output details relative changes in key tropical cyclone parameters, such as annual mean frequency and intensity, between current and future climate simulations. The project focuses on risks to buildings, infrastructure, and agriculture in the Pacific region.

Use Cases

• Modeling financial risk to infrastructure based on projected changes in tropical cyclone frequency and intensity.
• Assessing agricultural vulnerability in the Pacific region using peril matrices that detail changes in cyclone parameters.
• Incorporating climate change influence into hazard assessments for disaster preparedness and insurance modeling.
• Analyzing shifts in the mean latitude of tropical cyclone genesis for regional climate adaptation planning.

Strengths

• Project is a multi-organizational collaboration involving Geoscience Australia and other expert bodies.
• 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 cyclone behavior.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Primary file formats are PDF, DOCX, and HTML, suggesting the core data may be embedded within reports rather than standalone structured tables.
