Abstract
The islands in the west Pacific are highly vulnerable to tropical cyclones. These severe storms can devastate communities by destroying homes, crops and infrastructure, and result in loss of life. As part of the Pacific Climate Change Science Program, Geoscience Australia assessed the wind hazard from tropical cyclones for fourteen islands in the west Pacific as well as East Timor. The wind hazard was estimated for the current climate and projections were made for 2090 under the SRES A2 emissions scenario. This was achieved using a combination of historical tracks, tracks of tropical cyclone-like vortices detected in downscaled climate models and the Tropical Cyclone Risk Model (TCRM), developed by Geoscience Australia. The current climate wind hazard was found to exceed the wind loading design standards (HB 212-2002, 2002) by 15%-30%. The climate projections indicate a general decrease in wind hazard for the fifteen countries by 2090, associated with a poleward shift in storm genesis and peak intensity.
