On the Vertical Distribution of Wind Velocity near the Ground

Abstract

A new formula of the vertical distribution of wind velocity presented recently by Deacon
u =((az₀^1-β)/(1-β)){(z/z₀)^1-β-1}
where u denotes the wind velocity at the height z and a and β are constants, represents well many experimental results. But there seems to remain something to be examined. The author points out that the roughness parameter z₀ should vary according to the stability of the air layer, whereas Deacon considers this to be constants, and the form of a adopted by him,
a=(υ∗/k) z₀^β-1 ,
where, k=0.4, and υ∗ denotes the frictional velocity, is not correct.
