摘要

摘要: 利用实测的脉动场与平均场同步梯度观测资料研究近地层相似理论的适用性。结果表明:理论的核心--近地层为常数通量层的近似假设在有植被陆面上是基本不成立的。W'T'随高度明显减小;摩擦速度u*在30m高度范围内可增大24%左右。用相似理论关系式(或称作廓线通量法)得到的通量值只代表某高度层以下的平均值。

Abstract: The applicability of the similarity theory in the surfacelayer is studied by using the gradient observations of fluctuation and mean fields. The study results show that the approximation of constant fluxlayer can not come into existence basically in the surface layer over vegetation land. The decreases with height significantly. The increases about 50% with height within 12m over surface. The heat fluxcalculated by the profile-flux method represents the mean value within some heihght.
