| Zusammenfassung |
In recent decades, extremely hazardous windstorms have caused enormous
losses to buildings, infrastructure and forests in Switzerland. This has
increased societal and scientific interest in the intensity and frequency of
historical high-impact storms. However, high-resolution wind data and damage
statistics mostly span recent decades only.
For this study, we collected quantitative (e.g., volumes of windfall timber,
losses relating to buildings) and descriptive (e.g., forestry or insurance reports)
information on the impact of historical windstorms. To define windstorm
severity, normalized and declustered quantitative data were processed by
extreme value statistics. Descriptive information was classified using a
conceptual guideline. Validation with independent damage information, as
well as comparison with wind measurements and a reanalysis, indicates that
the most hazardous winter storms are captured, while too few moderate
windstorms are detected. Strong storms in the wind measurements and
reanalysis are thus added to the catalog.
The final catalog encompasses approximately 240 high-impact windstorms in
Switzerland since 1859. It features three robust severity classes and
contains eight extreme windstorms. Evidence of high winter storm activity in
the early and late 20th century compared to the mid-20th century
in both damage and wind data indicates a co-variability of hazard and
related damage on decadal timescales. |
