COALITION-4: Thunderstorm forecasting with artificial intelligence
The COALITION-4 algorithm produces precise, short-term thunderstorm nowcasts, in particular, for lightning strikes, heavy rainfall and hail. State-of-the-art deep learning methods are used to analyse radar, lightning and satellite observations. The project is also preparing to utilise the latest generation of geostationary satellites (GOES-R and Meteosat Third Generation). The COALITION-4 algorithm is based on a convolutional and recurrent-convolutional neural network architecture (RCNN), which is able to analyse spatial structures with convolutional layers and temporal developments with recurrent connections. The products of COALITION-4 will be used for severe weather warnings for the public, air traffic safety and disaster prevention. From 2020 to 2023, the EUMETSAT Fellowship "Seamless Artificially Intelligent Thunderstorm Nowcasts" held by Jussi Leinonen provided decisive momentum for this project.
