Abstract

Based on post-processing of measurements of vertical profiles of the wind velocity vector with an AV4000 minisodar in the boundary layer of the atmosphere at altitudes of 5–200 m, the thin structure of diurnal variations of a change of wind direction with altitude, that is, of the vertical wind veer, has been analyzed. The vertical wind veer, caused by many factors, including the advection force, the friction force, the Coriolis force, and the pressure gradient, is an important characteristic, because it is required to construct atmospheric models and to estimate the wind energy, pollution transport, and fatigue loading on high-rise buildings, bridges, and wind turbines. In the present work, the diurnal behavior of the angle of tuning of the horizontal wind velocity is analyzed with the vertical resolution Δz = 5 m and 10-minute time averaging.
