BoF Cloud Resolving Global Earth-System Models: HPC at its Extreme at ISC 2017

Due to the great importance of accurate weather and climate predictions, world-wide efforts are undertaken to develop high-resolution earth system models. We bring together leading international experts to report on their research efforts with focus on global high-resolution simulations. Reaching high resolutions of the earth system of 1km and below to, e.g., resolve clouds and convective motion, and running these simulations over adequate time intervals for actual predictions does not only require further insights into physics and current models, but it also particularly demands for extreme-scale high-performance computing beyond the capabilities that are currently offered by state-of-the-art supercomputers.
In our BoF, an overview on high-resolution weather and climate predictions, their feasibility and potential is given. This will yield insight into current and future computability of the underlying models for experts. It will also target the broader audience with interest in weather and climate simulation.
