Abstract: A study of wave motions in terms of diurnal variation, occurrence percentage, period, amplitude and height of waves in atmospheric boundary layer has been made using an acoustic sounder. The wave motions are usually associated with either surface-based inversions, elevated layers or rising inversions. Most of the time the observed waves have their periods ranging between 5 and 15 min and amplitudes between 100 and 150 m and usually occur in the height range 150-600 m. Power spectral densities of wave motions associated with different structures have also been computed.
