ECMWF - delivering forecasts over 10 times faster and cutting energy usage by 1000

2025-07-01
(Press-News.org) Embargo Tuesday 1st July 2025 06:00AM BST

 

Today, just over 100 days after the launch into production of the world first openly available 24/7 operational AI forecast model AIFS-Single, ECMWF (European Centre for Medium-Range Weather Forecasts) is unveiling the first ensemble model using Artificial Intelligence/Machine Learning. The new model, called AIFS ENS, will be available as open source to the user community over the coming weeks.

The new ensemble model outperforms state-of-the-art physics-based models for many measures, including surface temperature, with gains of up to 20%. At the moment, it works at a lower resolution (31km) than the physics-based ensemble system which remains indispensable for high-resolution fields and coupled Earth-system processes; ECMWF is therefore also exploring hybrid systems that leverage the strengths of both approaches.

This high accuracy ensemble model complements the portfolio of ECMWF services by leveraging the opportunities made available by machine learning (ML) and artificial intelligence (AI). The AIFS ENS relies on physics-based data assimilation to generate the initial conditions, but it can generate forecasts over 10 times faster while reducing energy consumption by approximately 1,000 times compared to traditional ensemble forecasting methods.

In February, ECMWF launched the first operational data driven model called AIFS Single. This model runs a single forecast at a time, known as a deterministic forecast. Despite its accuracy, there is much more value to users if they can access the full range of possible scenarios. This is known as ensemble forecasting, a technique developed and implemented by ECMWF more than thirty years ago.

Dr Florence Rabier, Director-General at ECMWF, states: “ECMWF has now created an operational collection of 51 different forecasts with slight variations for our Artificial Intelligence Forecasting System (AIFS), which is a significant achievement and complements our physics-based products.  But importantly, it’s not only us who are innovating. We are also working with and for 35 nations to advance weather science to improve global predictions. The availability of the AIFS ENS in conjunction with other ECMWF services will positively impact how national weather and meteorological services in our 35 Member and Co-operating States and beyond will be able to make their predictions and contribute to a safer society.”

ECMWF’s Director of Research, Dr Andy Brown, said: “This new milestone demonstrates our dedication to science-led innovations that are focused on delivering a machine learning forecasting model which pushes the boundaries of efficiency and accuracy, and it underscores our commitment to harnessing the power of machine learning for the weather forecasting community.”

ECMWF is leveraging the potential of what AI/ML can do for weather science with this latest model. This is part of its co-development of the award winning Anemoi framework with many of its Member States, which provides an open-source framework for training AI forecasting systems, including the AIFS.

ECMWF’s Director of Forecasts and Services, Florian Pappenberger, added: “We see the AIFS and IFS as complementary, and part of providing a range of products to our user community, who decide what best suits their needs. Making such a system operational means that it is openly available and comes with 24/7 support for our meteorological community. We will continue to engage with our Member States and our user community to ensure more and more parameters are added to suit their ongoing needs, and we will continue to enhance the model offered in line with how we push the capabilities of our physics-based system.”

Turning social fragmentation into action through discovering relatedness

2025-07-01
Discovering relatedness outside of a topical issue helps diverse groups to overcome differences and develop action for social change. The Kobe University addition to educational theory offers a framework to analyze and promote intersectional learning. To achieve social change in a fragmented modern society, individuals from diverse backgrounds need to join together and develop a common plan for action. This is important especially for education related to social change, where groups of varying involvement in a particular issue, e.g., learners and teachers, interact in a structured setting. Current educational theories fall short of offering a framework of how such cultural differences ...

Cheese may really be giving you nightmares, scientists find

2025-07-01
Scientists have found that eating too much dairy could ruin your sleep. Researchers questioned more than 1,000 students about the quality of their sleep, their eating habits, and any perceived link between the two, and found a strong association between nightmares and lactose intolerance — potentially because gas or stomach pain during the night affects people’s dreams.   “Nightmare severity is robustly associated with lactose intolerance and other food allergies,” said Dr Tore Nielsen of Université de Montréal, lead author of the article in Frontiers in Psychology. “These new findings imply that changing eating habits for ...

Study reveals most common medical emergencies in schools

2025-07-01
The three most common reasons schools called emergency medical services (EMS) were for neurological crises such as seizures, psychiatric conditions or substance abuse, and trauma related injuries, according to data from the national EMS registry analyzed by researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago. During the study period (2018-2022), school-based medical emergencies constituted 11 percent of EMS encounters for children and two-thirds resulted in transport to the hospital. Findings, published in Pediatrics, can help schools prioritize training so staff can respond even before EMS arrival. “While many schools have taken ...

The most effective diabetes drugs don't reach enough patients yet

2025-07-01
Subscribe to UCSF News A UCSF analysis has found that the newer generation of much more effective diabetes medications are reaching only a fraction of the patients who are recommended to take them based on new guidelines.   Type 2 diabetes (T2D), a condition in which the body can’t use insulin to clear sugar from the bloodstream, affects 1 in 10 Americans. It comes with grave health risks, including cardiovascular and kidney disease.   The study assessed medications that patients received within a year of T2D diagnosis. During the period under review — ...
