This paper presents the evolution of the wind profile in the atmospheric boundary layer during convective storms in the area of the Municipality of Bucharest. Sodar soundings were used to analyse the variations of the mean wind speed and wind speed shear velocity in the atmospheric boundary layer. The data was collected during, as well as 12 h before and 12 h after the nowcasting warnings for severe thunderstorms issued by the National Meteorological Administration between 2018 and 2021. Thus, the structure and evolution of the wind speed and wind shear velocity profiles in the atmospheric boundary layer was observed prior to, during and following severe convective episodes. The results are important in understanding the processes that take place in the atmospheric boundary layer during convective storms.
