Abstract
Tropical cyclones pose a significant threat to islanders in the tropical western Pacific. The extreme winds from these severe storms can cause extensive damage to housing, infrastructure and food production, whilst low lying areas can be adversely affected by storm surge inundation. As part of the Pacific Climate Change Science Program (PCCSP), Geoscience Australia is assessing the wind hazard posed by tropical cyclones for 14 islands in the western Pacific and Timor Leste. The assessment will cover both the current climate as well as projections for future climate scenarios. Wind hazard maps are being generated using Geoscience Australia's open-source Tropical Cyclone Risk Model (TCRM) that applies a statistical-parametric process to estimate return period wind speeds. The climate projections are produced by applying this model to downscaled storm tracks from global climate models. Two types of downscaled tracks are used for the projections: tracks of tropical-cyclone-like vortices directly detected in dynamically downscaled climate simulations and tracks derived from GCM's using a statistical/deterministic model (Emanuel 2006). The presentation will provide an outline of the method applied.
