Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

Spatiotemporal dynamics of the characteristics of atmospheric turbulence from the data of acoustic sounding
N.P. Krasnenko, L.G. Shamanaeva
634055, Russia, Tomsk, 10/3 Akademicheskii av., IMCES SB RASSpatiotemporal 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.
