Destination Earth: Digital Twins for weather and climate

Destination Earth (DestinE) is an ambitious initiative of the European Union to create a digital of our planet. As extreme weather becomes increasingly frequent and changes in climate more pronounced, there is an urgent need to forecast these events with even greater accuracy, to predict their impact on the environment, life and property. This talk will present the work done at ECMWF in DestinE in building the Digital Twin Engine and developing the Weather Extremes and Climate Change Adaption digital twins. We show the work done on developing and deploying the Digital Twin Engine on EuroHPC systems such as LUMI and Leonardo and share our experiences and challenges to date in using these systems for running the high resolution weather and climate digital twins.
