| Zusammenfassung |
| A storm loss model that was first developed for Germany is applied to the
much smaller geographic area of the canton of Vaud, in Western Switzerland.
24 major wind storms that struck the region during the period 1990–2010 are
analysed, and outputs are compared to loss observations provided by an
insurance company. Model inputs include population data and daily maximum
wind speeds from weather stations. These measured wind speeds are
regionalised in the canton of Vaud following different methods, using either
basic interpolation techniques from Geographic Information Systems (GIS), or
by using an existing extreme wind speed map of Switzerland whose values are
used as thresholds. A third method considers the wind power, integrating
wind speeds temporally over storm duration to calculate losses. Outputs show
that the model leads to similar results for all methods, with Pearson's
correlation and Spearman's rank coefficients of roughly 0.7. Bootstrap
techniques are applied to test the model's robustness. Impacts of population
growth and possible changes in storminess under conditions of climate change
shifts are also examined for this region, emphasizing high shifts in
economic losses related to small increases of input wind speeds. |
