Comparison of the contributions of turbulent and mesoscale processes to the wind field of the atmospheric surface layer

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.
