| Outline of Final Research Achievements |
When turbulent eddies are partially resolved in a numerical weather prediction model (i.e. large eddy simulation), the conventional parametrization of the surface layers are inadequate. How a surface layer parametrization should be in such a model is investigated by sensitivity experiments with a large eddy simulation, direct numerical simulation of turbulence, and wind tunnel experiments. We have also studies surface layer processes specific to the strong stable and unstable conditions.
