Exploring the past, present and future of HPC in meteorology
Overview and theme
As we celebrate 50 years of ECMWF, we invite you to the 21st edition of our biennial workshop on the use of high-performance computing (HPC) in meteorology, taking place from 15 to 19 September in Bologna, Italy.
This year's theme, Exploring the Past, Present and Future of HPC in Meteorology, highlights the transformative impact that high-performance computing has had over the years in advancing weather forecasting, climate modelling, and extreme event prediction and the crucial role it continues to play in the present and in the future.
With the rapid evolution of exascale computing, data-driven modelling, and sustainability challenges, this workshop provides a timely opportunity to reflect on the past, assess current developments, and explore future directions in computational meteorology.
We welcome researchers, industry experts, and policymakers to join us in examining cutting-edge advancements, engaging in insightful discussions, and sharing breakthroughs with leading scientistis and technologists shaping the future of the field.
Workshop description and aims
Every two years, ECMWF hosts a workshop on the use of high performance computing (HPC) in meteorology. The workshop provides an opportunity to bring together experts from across the national weather centres, academia and industry to discuss and present recent developments and impact of high performance computing for weather forecasting applications.
It is opportune, given the Centre’s 50 years of operation, to reflect on the role of supercomputing facilities in advancing insights into numerical weather prediction and how these services will need to evolve to meet the new challenges facing the meteorology communities.
Our aim is to provide a forum where users from our Member States and experts around the world can report on recent experiences, achievements and plans in the diverse field of high performance computing.
Call for abstracts
We welcome abstract submissions on topics including, but not limited to:
- HPC architectures and their role in meteorological applications
- Artificial Intelligence (AI), machine learning (ML), and data-driven approaches in meteorology – aligning conventional HPC and AI/ML techniques to benefit weather and climate
- Energy efficiency and sustainable computing in weather forecasting
- The future of exascale computing and emerging technologies
- Digital twins of the Earth
- Improving workflows and pipelines
- Software sustainability and maintenance - sharing best practices for open collaborative code development
- Advances in numerical weather prediction and climate modelling
Special session - UEF2025 meets HPC: The Using ECMWF Forecasts (UEF2025) workshop is taking place in Bologna as part of the 50th Anniversary celebrations, so there is an opportunity to join with this exciting event for half a day to explore crossover topics. We welcome abstracts which will appeal to both forecast user and HPC user communities.
Co-located as part of the weeklong celebrations is the 3-day Destination Earth Workshop. We are planning a joint session with Destination Earth, providing an opportunity to showcase Digital Twins relationships with HPC. We encourage abstract submissions that would be of interest to these sectors.
Please submit your abstract proposals for this workshop. The deadline for submission of abstracts is 30 April 2025.
Don’t miss the opportunity to engage with global experts as we enter the next era of computational meteorology!
Registration and format
The week begins with an opening plenary on the afternoon of Monday 15 September with sessions running each day and concluding on Friday 19 September at lunchtime.
The workshop will have a joint session with the DestinE Annual Meeting on the morning of Tuesday 16 September and a joint session with the Using ECMWF's Forecasts meeting (UEF2025) on the morning of Wednesday 17 September.
There is one registration form for all events taking place during the week. When registering, please select the relevant sessions you would like to attend.
Registration is now open and will close on 31 July 2025.
