Application of Meteorological Data in Computational Modelling of Wind over Real Terrain Topography

摘要

Owners of wind farms are interested in both annual mean wind speed and in forecasting wind speed for a few days. Considerable research effort is focused on computational modelling for wind energy assessment [1]. Local winds are influenced by synoptic situation as well as by specific topography. Therefore one should couple a Numerical Weather Prediction (NWP) model with additional small scale model. Especially in a complex terrain dependence of the local flow on the wind direction cannot be neglected. In this study we analyse this phenomenon for a particular site in a moderately complex terrain.
