An ECMWF Workshop on "Parametrization of clouds and precipitation across model resolutions" will be held from
Mon 5 to Thu 8 November 2012.
The ECMWF strategy for the development of physical parametrizations over the
next decade places particular emphasis on moist physics and there are many questions of how best to represent the hydrological, radiative and dynamical
impacts of cloud and precipitation across an increasing range of model resolutions.
This workshop will discuss latest advances in understanding some of the key
issues in parametrizing cloud and precipitation processes. The aim is to
provide advice on the direction of future cloud scheme developments, with a
particular emphasis on NWP as resolution increases from the 'large-scale'
towards the 'convective-scale'. Such issues include:
- The appropriate level of complexity and numerical formulation of microphysics.
- How to represent the impacts of sub-grid heterogeneity efficiently and
consistently across the range of model resolutions.
- How to get the most benefit from observations with an emphasis on evaluating
and constraining cloud and precipitation processes.
Further information will follow when a programme is available.
