A special unit of researchers of the Danish Meteorological Institute (DMI) has developed a regional weather model with artificial intelligence (AI) that could give timely warnings in 2,5 minutes in stead of more than 2 hours like the current weather models. They used one of the first supercomputers of its kind in Europe, the Gefion, the DMI announced in a statement on 17 April 2025.
For the moment the DMI researchers focused on temperature and wind, and compared it to existing computer models. The results were almost the same, but with the Gefion gigantically faster.
Predicting precipitation and cloud cover
“The pilot project has shown that DMI can utilize AI very quickly and effectively. We have several AI models in our pipeline for predicting precipitation and cloud cover that will be able to directly benefit from our experience, which has been gained in just a few months,” says DMI weather researcher Kasper Hintz.
About the Gefion AI supercomputer
The Gefion is operated by the Danish Centre for AI Innovation (DCAI), owned by the Novo Nordisk Foundation (85%) and the Danish Export and Investment Fund EIFO (15%). The machine was officially inaugurated in October 2024 by Danish King Frederik X. The name of Denmark’s first AI supercomputer comes from the mythological goddess for ploughing, foreknowledge and virginity. The machine is a Nvidia DGX SuperPOD, driven by 1,528 NVIDIA H100 Tensor Core processors with quantum computer technology.
So far, the DCAI selected five other projects to run on the Gefion. | © 2025 Marcel Burger, nordicreporter.com. Featured image: the Nvidia DGX SuperPod (Press photo: Nvidia)
