中文摘要:
      本文分析了官厅水库近水面层的温、湿、风廓线规律,指出水面的波浪状况对廓线规律有影响.给出了中性层结时水面粗糙度、动力摩擦速度及阻力系数与风速和浪高的关系.得出了适用于水面的层结订正函数.还分析了不稳定层结条件下的温度廓线规律,并对温、湿、风廓线的相似性问题进行了讨论.
英文摘要:
      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.
