Long-range forecast quality assessment in the climate time-scales is still very much in its infancy, and there is very little available science focusing on climate forecast verification. The increasing popularity of climate change studies, for reasons that are obvious, has put forward an increasing need and demand, both within the climate community as well as by the society, to learn about the quality and reliability of forecasts extending beyond the more commonly tackled short-to-medium-ranges.
The scope of the ECAC forecast verification session will deal both with the verification methodologies and with the verification results of extended range forecasts. Assessments of the societal impacts and of the economic consequences of long-range forecasts will also be highlighted. Contributions are invited on the following themes:
• Verification of extended range (weekly to monthly) forecasts
• Verification of seasonal to decadal forecasts
• Seamless verification to exclusively cover different forecast ranges
• User-oriented verification relating but not restricted to
- Transport disruptions
- Flooding events and river flows
- Sea ice extent effects
- Crop yields
- Disease incidences
