Popis: | 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. |
