Abstract: In this article we analysed rules of temperature, humidity and wind profiles over water surface layer in Guan Ting reservoier. It is shown that the wave states of water surface has an affect on the profiles. Some relatiomships of roughness length, friction velocity and resistance coefficient with wind velocity and wave height in neutral stratification have been given. We obtained a modifying function of stratification suitable for the water surface. Finally we analysed rules of temperature profile in unstable condition and discussed problem of similarity about temperature, humidity and wind profiles.
