Abstract
Mini-sodar measurements of wind velocity profiles in the 20–200 m layer have demonstrated the high efficiency of the use of mini-sodars in monitoring the fine structure of the atmospheric boundary layer (ABL) and in detecting jets and wind shear. An analysis of measurements of vertical profiles of the wind velocity and its vertical and horizontal components has shown that analytical approximations of the vertical profile of the horizontal wind velocity are possible for both neutral and unstable stratifications of the atmosphere. They are well described by a logarithmic law. The approximation constants are found and the errors associated with their use are estimated. The established physical trends and the obtained constants for the horizontal and vertical components of the wind velocity allow a description of their hourly and daily dynamics and can be recommended for use in ABL models intended for prognostic calculations (forecasting). The vector representation makes it possible to visualize the spatiotemporal dynamics of the wind field in the atmospheric boundary layer, in particular to estimate the shape and size of jets and wind shear in them.
