Abstract
In an array of microbarographs propagation characteristics of pressure fluctuations have been studied qualitatively. For one station the pressure data was digitized. It was found that acoustic and gravity waves can easily be distinguished on the recordings. The diurnal variation of the amplitude of acoustic waves was found to be mainly due to windinduced turbulence. There are highly significant correlations between the amplitude of both acoustic and gravity waves and classical meteorological parameters which can be summarized as follows: “the better the weather, the smaller the amplitude.” Under Foehn conditions the amplitude of gravity waves is increased while acoustic waves are highly damped.
