dc.description.abstractHorizontal scales and phase velocities of upper middle atmosphere (60–110 km) gravity waves determined from preliminary analysis of spaced wind observations obtained with a dual bistatic radar (Gravnet), based on and operated together with the Saskatoon MF radar are presented. In the observed period range of 10–100 min, horizontal scales increase from values of ∼44 km at 10 min to ∼211 km at 100 min, while observed phase speeds decrease from values of ∼72 m/s at 10 min to ∼34 m/s at 100 min. Typical rms perturbation velocities are ∼5 m/s. Calculation of intrinsic wave parameters indicates that in the intrinsic period range of 10–100 min, horizontal scales increase from values of ∼68 km at 10 min to ∼119 km at 100 min, with intrinsic phase speeds of ∼93 m/s at 10 min and ∼20 m/s at 100 min. The corresponding values of vertical wavelength are 30 km and 6 km, respectively.
