Temporal and spatial evolution of Atmospheric Gravity Waves(AGW) in the troposphere have been analyzed in vertical wind at Koto Tabang (0.20°S, 100.32°E) on 7 – 8 Dec 2005 during Coupling Processes in Equatorial Atmosphere (CPEA)-II campaign. AGWs with vertical wavelength of 2 – 3.5 km, horizontal wavelength of ~ 20-25 km and wave period of ~ 55 – 65 min were observed in the troposphere (3-10 km heights) during convection events. Observed variation in vertical wavelength with time during convection and after its termination suggests the characteristic features of convective sources and gravity waves, respectively in a convective environment.
► Gravity waves with λz ~ 2 – 3.5 km, λx of ~ 20-25 km, τg of ~ 55 – 65 min observed.
► Variation in vertical wavelength in accordance with variance of vertical wind.
► Downward phase propagation and increasing amplitude of waves with height.
