6th European Windstorm Workshop

Impacts and Predictability

21 June – 23 June 2017
University of Reading, UK

Conference board

  • Prof. Len Shaffrey, Department of Meteorology, University of Reading, Reading, UK
  • Prof. David Stephenson, Department of Mathematics and Computer Science, University of Exeter, UK
  • Prof. Christoph C. Raible, Climate and Environmental Physics and Oeschger Centre for Climate Change Research, University of Bern, Bern, Switzerland
  • Giovanni Leoncini, AspenRe, Switzerland


The aim of the workshop is to bring together scientists from dynamical meteorology and climatology as well as stakeholders from the insurance and engineering industries to share recent research ideas. The workshop is a continuation of a series of European storm workshops which started in 2011.


  1. Understanding the dynamics of European Windstorms
  2. Predicting European Windstorms from a few hours to a season ahead
  3. How have European Windstorm varied in the past? And how might they change in the future?
  4. Assessing and modelling the impacts, damage and losses from European Windstorms
  5. Improving the links between academia, operational centres and the insurance industry
