This paper proposes a wind prediction method for wind energy production using a mini Doppler sodar. In this method, short-term wind observation is conducted by a mini Doppler sodar and its wind speed data is correlated with long-term wind observation data obtained at other nearby sites such as AMeDAS. Then long-term wind prediction at the Doppler sodar site is implemented through multiple regression analysis based on the correlation between the short-term Doppler sodar data and the wind observation data at the other nearby sites. The results show that this method can predict the wind speed at the Doppler sodar site effectively. Then it is found that taking into account the atmospheric temperature and pressure in addition to the wind speed is more effective to raise the precision of the wind prediction in the multiple regression analysis.
