Similarity methods to derive turbulence quantities and mixed-layer depth from SODAR measurements in the convective boundary layer: A review

Abstract

A brief review is made of similarity methods which have been developed to calculate turbulence parameters and mixed-layer depth from SODAR measurements. Emphasis is placed on surface fluxes and mixed-layer depth. A variety of parametric relations valid in the convective boundary layer are surveyed and relevant similarity methods are outlined. The methods are primarily intended for flat and relatively homogeneous terrain. It is shown that, in most cases, horizontal homogeneity provides a less stringent constraint.
