ECMWF | Reading | 3-6 June 2019
A forum to discuss the use and performance of ECMWF's forecasts and related products
“Using ECMWF’s Forecasts” provides a forum for exchanging ideas and experiences on the use of ECMWF data and products. It is open to all ECMWF forecast users around the world and provides an opportunity to give feedback to ECMWF on forecast performance and on the range of available products, and to learn about recent developments of ECMWF’s forecasting system.
2019 theme: “The strength of ensembles”
National weather services and private weather providers have recognised the importance of ensemble forecasts and that information about uncertainty improves the ability to make decisions based on weather forecasts. ‘Forecasts are not complete without information on uncertainty’ was one of the closing messages of a past UEF meeting. In 2019 we will return to the topic of ensembles and their strength.
Twenty-five years ago ECMWF was one of the first forecasting centres to start issuing operational ensemble forecasts. The implementation of these ensembles induced a paradigm shift in numerical weather prediction (NWP). Centres moved from providing a single forecast to issuing a range of forecasts that can be used to identify possible future scenarios, to compute the probability of events of interest, and in general to estimate forecast confidence levels. Today, ensembles are routinely used to provide estimates of the probability distributions of analyses and forecasts. Great progress has been made to aid their visualisation and communication to wider audiences.
The UEF meeting will offer an opportunity for participants to showcase the strength of ensembles. The meeting will also provide a framework where participants can share their experiences with ECMWF data and provide feedback on ECMWF products.
UEF2019 will focus on the following thematic areas:
Processing of model outputs: this session will be dedicated to model output developments. Case studies demonstrating the use of new model output developments are welcomed.
Visualisation: in this session we welcome contributions about the visualisation of ensembles and derived products
Verification and diagnostics: this session will focus on the assessment of the skill and consistency of ensemble forecasts, including impacts.
Application and Impact forecasting: this session will look at how weather forecasts are used in applications for sectors such as water, energy, agriculture, fire and health. It will feature case studies showing the strength of ensembles in such applications.
The programme will contain talks by participants and ECMWF staff, keynote addresses on specific topics to stimulate discussion, and interactive sessions to encourage networking.

Registration and abstract submission
The maximum number of participants is set at 100; priority will be given to applicants who submit an abstract.
We are seeking submissions in the following formats:
