説明

To improve the forecast accuracy of the annual energy production from wind power, the characteristics of the atmospheric stability distribution are summarized using data from wind observation towers at ten sites in Japan. The bulk Richardson numbers indicate that stable conditions prevailed at seven out of ten locations. / An analysis of each met mast indicated that the prevailing stability varied by season and differed not only according to the area but also according to the wind farm scale. These differences are thought to result from the distance to the sea and the wind shear. In addition, we compared the results according to the observational data and the bulk Richardson number calculated using the Weather Research and Forecasting model（WRF） during each season. The prevailing atmospheric stability at the observation points is affected by the atmospheric stability of the land and the surrounding ocean. / The results of previous research and this study indicate that considering the atmospheric stability enables more correct estimations of the annual wind power energy production. If possible, seasonal and local differences in the atmospheric stability should be considered to better estimate the wind power generation.
