While the use of WTGS expands over the world, complex terrain has become important candidate as the site proposed for a WTGS. In the complex terrain, contribution of local topographic effects to the wind energy resources is quite large and intensity of wind turbulence, which brings about complicated aerodynamics loads on the wind turbine, is much larger than that over the flat terrain. The purpose of the present work is to investigate the turbulence characteristics of the wind flow over complex terrain such as mountainous region. The wind measurements were carried out at Shitara-cho in Aichi during the period from November 19th to December 10th in 2003, using three meteorological masts and ten anemometers. The influence of the slope on the turbulence has been evaluated by examining the power spectrum of the wind fluctuation.
