摘要
利用西藏日喀则、那曲１９９３年７月至１９９４年４月近地面层梯度观测资料，采用近地面层相似理论方法，计算了观测期间地面粗糙度、平均曳力系数、平均动量通量、平均感热通量和平均湍流系数，讨论了它们与稳定度的关系，给出了日变化个例。
With the data obeerved on the surface of Rikeze and Naqu in Tibet from July of 1993 to April of 1994，the surface roughness，the mean drag coefficient，the mean momentum flux，the mean sensible heat flux and the mean turbulent coefficient are calculated in the surface similarity theory. Their relations with the stability are discussed and the samples of their daily variation are given.
