Workshop on numerical and computational methods for simulation of all-scale geophysical flows

ECMWF | Reading | 3-6 October 2016

Workshop description

The workshop aimed to bring together scientists working on the various aspects of model development. In particular, interdisciplinary research and progress on numerical schemes, parallel and energy-efficient computing, coupling of resolved/subgrid-scale parametrised processes and multiscale interactions that could be relevant for numerical weather prediction were welcomed.

The workshop continued a successful series of scientific and technical exchange using forward-in-time differencing for fluids with the EULAG model, bringing together different disciplines of geophysical modelling research, with previous workshops in Bad Tölz, Sopot, Loughborough, and Mainz.
