چکیده انگلیسی
Rayleigh lidar temperature data collected at Gadanki (13.5°N, 79.2°E) during two campaign periods in 1999 and 2000 have been analyzed to study the planetary wave activities in the stratosphere and lower mesosphere. Attention has been given to the Rossby-gravity (RG) wave, fast Kelvin wave, and slow Kelvin wave with remarkable periodicity of 3.6, 6.5, and 16 days, respectively. The well-known Lomb-Scargle periodogram (L-S) analysis was performed on the temperature profile to extract the wave characteristics. The analysis indicated the dominance of these waves in the stratosphere and mesosphere. The results obtained are consistent with other measurements based on radar, rocketsonde or satellite.
