ECMWF | Reading | 13 - 16 November 2017
The workshop will bring together experts in numerical weather prediction and climate modelling to discuss and propose ways forward on the modelling of physical processes in the greyzone of horizontal resolutions ranging from 1 km-10 km grid-spacing. The workshop aims to shed light on the greyzone topic from different angles to identify novel approaches and development opportunities.
Topics discussed will include the required complexity of cloud microphysics, the interaction of cloud microphysics, convection and boundary layer turbulence, the interaction with and the representation of the surface heterogeneity, including orography and vegetation over land and the sea-surface state over the ocean, and the physics-dynamics interplay with increasing resolution, including difficulties and opportunities arising from emerging HPC architectures.
These will be discussed in the context of the inherent uncertainty of the above modelled processes (or of the underlying HPC hardware) and in view of ECMWF's ten year strategy to develop a 5km global ensemble.
