Proceedings of SPIE Vol. 10833 : XXIV International symposium оn atmospheric and ocean optics : atmospheric physics, 2018, Tomsk, Russian Federation. P. 108333Y-1-108333Y-5Abstract: In the report, spatiotemporal dynamics of the turbulent kinetic energy (TKE) retrieved from minisodar measurements of
three wind velocity components in the range 5–200 m during 6 days in autumn is investigated. The results obtained
demonstrated that the TKE increased with altitude, which is in agreement with the available literature data. In the
surface 50–100 m layer, it slightly increases with altitude. The diurnal variations of the vertical profiles of the TKE are
analyzed. The presence of maxima and minima in the daily behavior of the TKE was detected that can be explained by
the effect of meteorological conditions. The influence of the averaging time was also estimated.
