Foreword
The WWRP/WMO Workshop on the Verification of Quantitative Precipitation Forecasts will be organised by the Scientific Steering Committee of WWRP (World Weather Research Program) and will be co-sponsored by WMO. Participants are expected to come from the major weather centres and laboratories world-wide which are active in the area of verification.
The workshop will be conducted in English. It is planned to produce a workshop report to be published as a WMO Technical Report which will include the papers submitted by the participants and a summary of discussions/recommendations.
The Scientific Steering Committee of WWRP organises a workshop on verification for the first time. The organisation is motivated by a need to address more strongly the verification issues and, in accordance with WWRP strategies promoting actions for further understanding of the science and technology involved in improved weather prediction, the workshop shall be focused on verification of high-impact weather events in connection to Quantitative Precipitation Forecast (QPF). Hence, the accent shall be put on verification of heavy convective or orographic rain, on heavy snow fall, etc.
It is expected that after an overview of the state of the art for the QPF verification strategies the participants shall discuss improvements of these techniques. Each important item shall be introduced by an invited lecture. Interesting results from a few case studies are expected as well to be presented. A report shall be drawn on recommendations regarding future Research & Development actions on verification of QPF. Because of the need of an in-depth discussion and of drafting the conclusions, the workshop shall be limited to a relatively small number of participants (up to thirty).
