Using ECMWF's Forecasts (UEF2021)

UEF2021 focuses on the following thematic areas:

• Severe weather and hazard forecasting including extremes and impacts: this session invites new and novel tools, products and ideas for severe weather and hazard forecasting.
• Forecasting in extraordinary circumstances: submissions to this area are about how extraordinary circumstances were overcome to ensure forecasts and services continued to be delivered.
• Unforeseen impacts of extraordinary circumstances which affected forecasting or modelling: this session looks at unanticipated impacts, for example fewer aircraft observations during the COVID-19 pandemic, and what impacts these caused.
• Extraordinary collaborations: submissions to this area explore the successes, benefits and challenges of collaborative activities either during extraordinary circumstances or to overcome issues faced by the meteorological community.

There will also be a special session run by IPMA Portugal:

• Recent developments in assessing societal impacts of extreme meteorological events at a national level: Knowledge on extreme meteorological events and their impacts are key elements for managing daily activities of modern society. NWP forecast performance has significantly increased in the past decades, therefore strongly supporting the activities of National Meteorological Services. However, the impacts of extreme meteorological events are related not only to weather but also to environmental components, that NWP models do not account for. The aim of this session is to bring together the most recent developments regarding extreme meteorological events with a particular focus on how to the impacts on society have been treated at national level.
