Statistical analysis of results of long-term continuous 8-day measurements of three components of wind velocity vector with a minisodar in the atmospheric boundary layer is presented for altitudes of 5–200 m and their interdaily variations are studied. The temporal dynamics of vertical profiles of the wind velocity components demonstrates that there are linear segments on the vertical velocity profiles for which the altitude behavior of the velocity components is well approximated by a linear dependence. The analysis of interdaily variations of three wind velocity components has allowed us to establish that all wind velocity components increase with sounding altitude. Attention is drawn to the synchronous character of occurrence of the maxima and minima of x- and y-components. For all components, the semidiurnal behavior (with the velocity decrease since midnight till noon and its subsequent increase since noon till midnight) is clearly traced that can be explained by morning warming and evening cooling of the underlying surface accompanied by the most intensive changes of wind velocity components.
