The paper discusses results of the analysis of vertical profiles of the normalized structure characteristic of air temperature CT2 in the atmospheric boundary layer under conditions of daytime convection. The experimental data have been obtained with Volna-4M acoustic Doppler radar (sodar) (Akademgorodok, Tomsk, Russia). The profiles were auto-normalized to the value of CT2 at the height H = 100 m. The results obtained in daytime (11:00-16:00 Local Time) in the warm period (July-August) of 2015 have been analyzed. The shape of the sodar vertical profiles of CT2 has been compared with results by other authors. The presence of a break in the CT2 profile at heights of 60-80 m can be noticed.
