Wind maps are useful to estimate the wind energy potential, the impact of wind on crops and buildings, the transport of pollutants and for meteorological studies. The Department of Meteorology has been recording wind velocity in twenty-two stations for many years in Sri Lanka. Whilst the surface wind velocities have been recorded in all stations, the upper air wind velocity has been recorded at only four stations. Thus, surface and particularly upper air wind data is sparse for Sri Lanka. Hence, a model to construct the wind field for the entire island will be useful.
