Scientific paper

A systematic study was carried out of short-period gravity waves with periods in the range of the variation of the Brunt period with height to investigate the mechanism of this variation, together with an investigation of the Doppler ducting produced by the variation in horizontal winds. The frequency dispersion at a fixed popagation direction and the direction dispersion at a fixed frequency were examined in a COSPAR background atmosphere with zonal and meridional winds. The results show that these short-period waves were ducted and, unlike structural ducting or dissipative ducting, the Brunt ducting mechanism could by itself produce fully guided modes. In the presence of winds, the combined Brunt-Doppler ducting could produce both the fully guided and partially guided modes.
