Losses related to extreme winds make up over half the insurance payments related to weather and climate extremes in Norway. Planning for and mitigating these impacts requires detailed knowledge of the extreme winds and their relation to damage. The project aims to increase understanding of how windstorms and damage is related and incorporate this knowledge in a useful way for impact and adaptation purposes through the development of detailed return values for extreme winds and storm-damage functions using four decades of nationwide insurance data on municipality level. The project will further quantify possible changes in extreme winds due to future climate change and their uncertainty by analyzing an ensemble of regional climate models and link the results to the developed storm-damage functions. Future changes in exposure will be addressed through national demographic scenarios and the benefit of reducing the vulnerability by assuming that building standards are strengthen to prevent losses for winds below a certain return period will be conducted. The project will have involvement from several user communities. The most important being the Norwegian Directorate for Civil Protection (DSB) which has the national responsibility to follow up local, regional and national preparedness and emergency planning. End-user results and data sets will be disseminated through the National Climate Service dissemination system and the underlying data will be made accessible through the national e-infrastructure for scientific data.
