Tropical Cyclone Risk Matrices for Pacific Region Under Climate Change

Peril matrices detail relative changes in tropical cyclone parameters between current and future climate simulations. The output is from a collaboration between DIICCSRTE, Geoscience Australia, PCRAFI, and AIR Worldwide. The record was last updated in April 2026.

Use Cases

• Model changes in annual mean frequency of tropical cyclones for future climate scenarios.
• Analyze shifts in the mean latitude of cyclone genesis to project regional hazard exposure.
• Assess financial risk to buildings by integrating relative changes in mean maximum intensity.
• Compare fractional changes in cyclone behavior parameters between GCM simulations.

Strengths

• Analysis incorporates future climate change projections from GCM simulations.
• Collaboration involves multiple specialized organizations (DIICCSRTE, Geoscience Australia, PCRAFI, AIR Worldwide).

Limitations

• Specific row counts, column details, and sample data are unavailable.
• Primary outputs are documented reports (DOCX, PDF, HTML), not raw structured data tables.
• Geographic scope is limited to the Pacific region.
