4th Workshop on European Storms

8 - 10 September 2014 IPMA - Instituto Português do Mar e da Atmosfera, I.P. Lisbon, Portugal

Conference Board

  • Margarida L. R. Liberato
  • Isabel F. Trigo
  • Alexandre M. Ramos
  • Ricardo M. Trigo


As on previous workshops, the main objectives of the workshop are:

  • to share recent research ideas,
  • to establish links with users of research on European storms and
  • to develop strategies on how to grow activity in this important area in the future.

This 4th workshop follows on from the previous excellent workshops organised in Exeter (2011 and 2013) and in Leeds (2012). The format is very similar including talks, posters and breakout discussions.
