Abstract
Island nations in the South Pacific region are expected to be particularly vulnerable to the impacts of climate change. Tropical cyclones are one event that could potentially devastate the region in a warming world. To assist in evaluating this threat, Geoscience Australia has developed a Tropical Cyclone Risk Model (TCRM) to provide detailed hazard information to help guide policy makers and infrastructure planners. TCRM is a statistical-parametric model that generates synthetic tropical cyclone tracks via a Monte-Carlo process that requires the climatology of tropical cyclones to create probability density functions. These synthetic tracks can then be translated into wind hazard maps, using idealized wind profiles, to show return periods for severe winds and to inform detailed risk assessments. As part of the Pacific Climate Change Science Program (PCCSP), Geoscience Australia has been asked to provide cyclonic wind hazard assessments for the region and also to provide projections of how this risk will be affected by climate change. The presentation will provide a brief overview of previous work on cyclonic wind hazards in the South Pacific region, followed by an outline of the research that Geoscience Australia will be performing for the PCCSP.
