Validation of the downscaling method for the high-accuracy wind map

Abstract

Wind speed and wind power map around the Pacific side of Tohoku district are created by atmospheric model, and validated by various kinds of observation data including land and on the sea. In the downscaling calculation of wind filed from the coastal area to on the sea, it was found that the accuracy of the boundary condition had the more importance than the grid size and the quality of atmospheric model. Wind speed in coastal area showed the high correlation and small mean error less than 1 m/s with observation data.
