Our Use Cases

The COMPASS use cases provide a real-world testbed and insights in the feasibility of attributing compound extremes and their impacts to climate change.
COMPASS will develop a harmonised, yet flexible methodological framework that furnishes event-specific steps for the attribution of climate change as a driver of impacts in complex extremes. This framework will be validated and applied to a set of diverse use cases, that cover compound events, sequences of events and cascading events.

Our selected use cases cover complex extremes for various hazard types and impact contexts:

  • France: compound flooding and storm during cyclone Xynthia in 2010
  • United Kingdom: cluster of winter storms in 2013-2014 and drought combined with a heatwave in 2022
  • Mozambique: compound flooding due to tropical cyclones Idai, Kenneth and Freddy in 2019 and 2023
  • Caribbean: sequential tropical cyclones Eta and Iota in 2014
  • Poland: single-country use case, not connected to a particular event, demonstrating an operational system for drought and heatwaves
  • A second set of additional use cases will be defined during phase II of the project
