Аннотация: In this paper, we test the hypothesis about the presence of a diagnostic relation between the second and third moments of hydrodynamic quantities c1 and c2 in the atmospheric boundary layer above a geomet-ricallycomplexsurface:w'c'c' =CS σ w'c'.Totestthisrelation,a7-monthseriesofhigh-frequencymea- 12 c1c1 2surements on an eddy covariance tower installed at the Meteorological Observatory (MO) at Moscow State University is used. The optimal methods for analyzing the reliability of the dependence are evaluated based on the statistical distribution of third moments. A statistically valid estimate of the validity of the tested hypothesis is obtained on a large series of data under the conditions of the urban underlying surface for the first time. The effect of stratification conditions and the nature of the underlying surface in the area of flux formation on the fulfillment of the relation is studied. The relation is established to be valid in 80% of casesfor third moments w'w'T', w'T'T', w'u'u' and w'v'v'.
