Turbulence in plant canopies (II)

Abstract

A differential equation, which prescribes velocity distribution in plant canopies and was derived in a previous paper, is solved for a given plant density-height relation, i.e. a parabolic relation. The obtained solution contains a Bessel function of νth order and represents a probable profile which is connected to a logarithmic profile, in the space over the plant canopy. Correspondingly, the roughness parameter and the zero-plane displacement are determined uniquely. Also the depth of the laminar sublayer is discussed and is proved to vary inversely with the frictional velocity. © 1965, The Society of Agricultural Meteorology of Japan. All rights reserved.
