Abstract
The talk will review the use of HPC in numerical weather prediction, climate monitoring and research. Starting from the early foundations of modern numerical weather prediction, this talk will describe advances in the field, culminating in the ongoing efforts to create digital replicas of the Earth, e.g. in initiatives like the European Commission's Destination Earth. Digital Twins of Earth encapsulate both the latest science and technology advances to provide near-real time information on extremes and climate change adaptation in a wider digital environment, where users can interact, modify and ultimately create their own tailored information.
Recent projects have demonstrated that global, coupled storm-resolving (or km-scale) simulations are feasible and can contribute to building such information systems and are no longer a dream thanks to recent advances in Earth system modelling, supercomputing and the adaptation of weather and climate codes for novel computing architectures. Such simulations for example explicitly represent essential climate processes, such as deep convection and mesoscale ocean eddies, that today need to be parametrised even at the highest resolution used in global weather and climate information production. These simulations, combined with novel data-driven deep learning advances, thus offer a window into the future, with a promise to significantly increase the realism of Earth system information. Despite the significant compute and data challenges, there is a real prospect to better support global to local climate change mitigation and adaptation efforts, and complement the existing information derived from today's operational systems.
About the Speaker
Nils Wedi obtained his PhD from the Ludwig-Maximilian University of Munich, Germany. His 27-year career at the European Centre for Medium Range Weather Forecast (ECMWF) encapsulates a diverse range of work both technical and scientific. He is the Digital Technology Lead for Destination Earth at ECMWF, a recent initiative which is part of the European Commission’s Green Deal and the Digital Strategy. Destination Earth will create a high precision digital model of the Earth to model, monitor and simulate natural phenomena and related human activities. Prior to this appointment, Nils led ECMWF’s Earth System Modelling section. He actively collaborates with researchers worldwide, in particular through his role as a co-chair of the WMO working group on numerical experimentation (WGNE), a key link between weather and climate research.
