Similarity methods to derive turbulence quantities and mixed layer depth from sodar measurements in the convective boundary layer: A review.
Melas D.
[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. Finally, some limitations of the existing methods are presented and discussed. It is proposed that the most serious errors are mainly associated with the poor accuracy of some parameters measured by the SODAR and also with the limitations of the theoretical basis employed.
