DESCRIPTION:\n“Using ECMWF’s Forecasts” is a forum for ECMWF forecas
 t users to exchange ideas\, share experiences\, and discuss the use and pe
 rformance of ECMWF’s forecasts and related products\, helping to ensure 
 that ECMWF’s services continue to meet user needs.\nOpen to all ECMWF fo
 recast users\, the forum provides opportunities for attendees to present t
 heir work\, give feedback on forecast performance and available products a
 nd services\, and stay informed about ECMWF’s latest updates and plans. 
 Dedicated time is included for sharing experiences and networking with ECM
 WF staff\, ECMWF Member and Co-operating States\, and other users from aro
 und the world.\nUEF2026 theme: Extreme Temperature Forecasts\nTemperature 
 is a fundamental variable that affects everyone and everything\, commonly 
 with significant impacts. UEF2026 will focus on temperature forecasting wi
 th particular emphasis on extreme hot (heatwave) and cold (cold wave) even
 ts.\nOverview\nECMWF provides a wide range of temperature forecast product
 s and data\, spanning medium-range (15 days)\, sub-seasonal and seasonal t
 imescales. These include the well-known charts for 2m temperature and the 
 850 hPa level\, products that quantify uncertainty such as meteograms\, an
 d those enable the calculation of probabilities for temperature thresholds
  being exceeded or falling below thresholds. Derived products like the Ext
 reme Forecast Index (EFI) act as an 'alarm bell' for unusually hot or cold
  conditions worldwide in the medium-range to sub-seasonal ranges\, while S
 EAS5 provides seasonal outlooks of temperature anomalies. Member and Co-op
 erating States utilise ECMWF temperature data through downscaling and post
 -processing activities to better forecast temperatures and extremes in the
 ir areas. Together\, these products and data support temperature forecasti
 ng for a broad range of applications and decision-making contexts. Over r
 ecent decades\, temperature forecast skill has improved consistently\, dri
 ven by advances in numerical weather prediction including coupling with ot
 her Earth System components (land\, ocean\, sea-ice\, atmospheric composit
 ion) and data assimilation methodologies implemented through ECMWF model u
 pgrades. More recently\, ECMWF's machine learning models\, AIFS and AIFS 
 ENS\, have demonstrated strong performance for temperature forecasting\, i
 n many cases matching or exceeding traditional NWP approaches. In addition
 \, high-resolution simulations from the Destination Earth programme provid
 e valuable case studies that deepen understanding of temperature extremes 
 and their forecasting. Beyond weather timescales\, ECMWF contributes to c
 limate monitoring through the Copernicus Climate Change Service (C3S) with
  applications such as the Climate Pulse and reports like the Global Climat
 e Highlights. The key dataset\, ERA5 reanalysis\, facilitates research on 
 climate variability and change\, supporting analysis of how long-term temp
 erature trends are impacting the world. UE2026 will bring together the fo
 recasting community to advance understanding\, share expertise\, and stren
 gthen collaboration in temperature forecasting across timescales.\nCall fo
