Winter wind storms
Wind storms globally pose the most important natural hazard from a socio- economic perspective. For the European continent, it is especially winter storms related to synopticscale extra-tropical cyclones that often affect several countries at the same time bearing high risk of cumulative loss.

Wind storms globally pose the most important natural hazard from a socio- economic perspective. For the European continent, it is especially winter storms related to synopticscale extra-tropical cyclones that often affect several countries at the same time bearing high risk of cumulative loss. Societal and economic stakeholders are interested in different aspects regarding these phenomena. On the one hand, (re-)insurance loss modeling requires high spatio-temporal resolution information for winter storms that happened in the past as well as physically consistent scenarios of storm events that could happen. On the other hand, socio-economic planning activities would benefit from any reliable information regarding the frequency of damage-prone storm events for the upcoming seasons and years. The current thesis addresses three aspects in this context: (i) It further develops an objective impact-oriented identification scheme regarding such wind storms. (ii) State-of- the-art decadal climate forecasts are analyzed whether they can provide skillful predictions of Northern Hemisphere winter storm frequency.
