  • Article

Spatiotemporal dynamics of three wind velocity components, longitudinal and transverse structure functions of the wind velocity field, structure characteristics of temperature and wind velocity, turbulent kinetic energy dissipation rate, and outer scales of temperature and dynamic turbulence is analyzed in the atmospheric boundary layer. A closed iterative algorithm of sodar data processing is used that takes into account the turbulent attenuation of acoustic waves propagating along the sounding path and allows vertical profiles of the structure characteristics of temperature and wind velocity fields to be reconstructed simultaneously and hence their interrelation to be investigated. The efficiency of the suggested algorithm is confirmed by a comparison of the results obtained with the data of lidar sensing and by the agreement of the results obtained with the available theoretical estimates.
