An experimental investigation of the wind wave is presented. The objective of the field is the non-stationarity of wind wave groups. The main goal is to investigate the change of the power spectral density function during the time when the group exists. To describe the time-frequency energy properties of wind wave the short time Fourier transform and spectrogram are used. It is made a hypothesis that the process of the energy transmission from high to low frequencies during the storm is realized not continuously but in portions exactly in the wave groups.
