Abstract
Climate change is expected to increase severe wind hazard in many regions of the Australian continent with consequences for exposed infrastructure and human populations. The objective of this paper is to provide an initial nationally consistent assessment of wind risk under current climate, utilizing the Australian/New Zealand wind loading standard [1] as a measure of the hazard. This work is part of the National Wind Risk Assessment (NWRA), which has been commissioned by the Australian Federal Government (Department of Climate Change and Energy Efficiency) to highlight regions of the Australian continent where there is high wind risk to residential structures under current climate, and where, if hazard increases under climate change, there will be a greater need for adaptation. This assessment is being undertaken by separately considering wind hazard, infrastructure exposure and the wind vulnerability of infrastructure (residential buildings only). The NWRA aims to initially provide a benchmark measure of wind risk nationally (current climate), underpinned by the National Exposure Information System (NEXIS) developed by Geoscience Australia and the wind loading standard [1]. The outputs of the NWRA will be crucial to informing climate change adaptation options regarding severe winds which should be of significant concern to decision-makers in planning, construction, emergency services, and the insurance industry, as well as the community as a whole. The methodology developed at Geoscience Australia to analyse the direct impact of severe wind on Australian communities involves the parallel development of the understanding of wind hazard, residential building exposure and the wind vulnerability of residential structures. Here we provide a preliminary indication of the current climate wind risk expressed as annualized loss.
