Abstract
Results of statistical analysis of eight-day spatiotemporal dynamics of the total kinetic energy flux density vector (the Umov vector) obtained by post-processing of AV400 minisodar measurements of the wind velocity vector components and their variances in the boundary layer of the atmosphere at altitudes from 5 to 200 m are presented. It has been shown that the magnitude of the total Umov vector, including its mean and turbulent components, is low in the surface layer of the atmosphere at altitudes up to 50 m. From 50 to 100 m, it increases, at altitudes above 100 m, the rate of it growth intensifies, and its largest values are observed at altitudes of 150–200 m. However, at any time, the maximum magnitude of the total Umov vector was observed at altitudes of 100–200 m that are most dangerous for flight of light unmanned aerial vehicles. During 8-day observations, the maximum values of the Umov vector were observed in the morning and evening hours.
