Abstract
The mixed moments of wind vector components on the turbulent and meso-gamma scales calculated from experimental data obtained in the surface air layer at an altitude of 10 m are compared. The statistics of mixed moments for several months in different seasons of 2021 is presented. The dependence of mixed moments on the wind velocity and temperature stratification in the surface air layer is briefly analyzed. The values of mixed moments formed by the wind field components on the meso-gamma scale are comparable with those formed by the mixed moments of turbulent components of the wind vector.
