Abstract

With the use of the wavelet-transform, the analysis was performed of time series of wind velocity measured by the Doppler lidar at different altitudes. The possibility of identifying of regular structures with consistent behaviour was demonstrated. It was shown that at a local phase adjustment of equally-scaled fluctuations, for these structures there can be identified the time-frequency intervals of strong coherence. This approach can be effective in identifying and studying coherent formations in the atmosphere.
