THE INFLUENCE OF THE SURFACE’S ROUGHNESS UPON THE WIND PROFILE IN THE UPPER PLANETARY BOUNDARY LAYER OVER DAIREN

The wind data from free balloon at Dairen for the year 1955 are grouped into four sets, namely:wind from sea at 11:00 and at 23:00;wind from land at 11:00 and at 23:00. By using the results obtained earlier by one of the authors, the calculated wind profile agrees with the observed wind distribution.Comparing the different distribution of the turbulent coefficient K with height for the four conditions, the influences of the stability and the surface's roughness on the wind profile are discussed.
