| Abstract: | The values of roughness length for momentum z
0and zero-plane displacement d
0over a hilly rough complex region with vegetation were evaluated without any assumption concerning z
0and d
0.It was found that for widely scattered profile data, the method of least squares will not give a reasonable result in determining the roughness parameters. For this purpose, the method of maximum correlation was introduced instead. This method gave a fair result for captive balloon observations conducted in hilly terrain mainly covered with forest in the northwestern part of the Kanto Plain, Japan. |
