The aim of the workshop is to discuss how to develop NWP
parametrisations related to forecast of stable boundary layer weather.
We want to bring together researchers, model developers and
forecasters for three days with presentations and discussions. The
expected outcome of the workshop is an overview of the current
problems and ongoing studies, recommendations and coordination of
plans in the European NWP community.
The suggested topics for the workshop include:
Models and the Nordic temperature problem. Nordic temperature problem, common to practically all NWP models, is related to the difficulty to forecast reliably the near-surface temperature in the conditions of stable stratification, especially in winter. Solution of the problem requires a complex approach to handling of the surface energy balance, depending on the surface properties and heat and moisture under the surface, on the radiative and turbulent fluxes in the surface layer and above.
Forecasting fog, stratus and visibility. Forecast of visibility, depending on low clouds and fog, is of great practical importance for aviation, land and sea transport. Improvement of these forecasts requires understanding of moist processes in the planetary boundary layer, interacting with the large-scale synoptic processes and influenced by the surface properties.
GABLS4 stable boundary layer model intercomparison. Preparations for the next GEWEX Atmospheric Boundary Layer Study have started, with the aim of model-observation intercomparison in the strong stable stratification conditions over Antarctica.
New developments in turbulence parametrisations. New theoretical research on turbulent energy and fluxes in the atmosphere and ocean may provide new parametrisation possibilities for the NWP, climate and air quality models.
Researchers and research students working with these topics are welcome to make a presentation of 20 - 30 minutes. A few invited presentations will be given on the main topics. Discussion and formulation of suggestions for further research and applications are essential for the workshop and will be devoted sufficient time.
The workshop will be arranged in the meeting room "Tellus" of the Finnish Meteorological Institute. Part of the presentations may be made available in real time via a video conference system.
