Abstract

The mixed moments of the wind vector components are compared when these components are decomposed into deterministic, meso-gamma-scale, and turbulent parts. The results of wind measurements at heights of 5 and 10 m in August 2021 at a site with natural landscape (large grassy meadow) are used. It is shown that meso-gamma-scale variations of the wind field should necessarily be taken into account in problems of modeling (predicting) the state of the atmospheric surface layer.
