| Abstract: | Summary Radar data from long-enduring meteor trails observed during two different campaigns carried out at the CNR station in Budrio (45° N, 11° E) near Bologna in Autumn of 1980 and 1985 reveal that the wave field near the mesopause is composed of a superposition of wave motions to be connected possibly to propagating internal gravity waves. The measured vertical wavelengths ranged from 2 to 13 km with dominant wave activity at values between (2÷3) km and (6÷7) km. The observed small-scale wave activity suggests processes and effects of wave field saturation and of convective or dynamical instability. |
