We will scope and develop a catalogue of extreme weather impact events, providing metadata and links to databases containing meteorological, hazard, impact and response information for significant cases that may be used to advance knowledge of prediction and warning. Conduct case study across the entire chain and survey of operational centers for their practice on high impact weather warning. Providing guidance to weather services with evidence.

The aims are outlined in a draft concept note. It has been agreed to merge this proposal with a related proposal from the WWRP SERA (Societal and Economic Research Applications) working group aimed at studying and evaluating the range of value chain approaches.
