Two days of continuous data acquired using the Equatorial Atmosphere Radar ( EAR), Boundary Layer Radar (BLR), X-band radar, radiosonde and other collocated facilities were analyzed to demonstrate the relationship between the evolution of strong convection and its role in forcing gravity waves that penetrate from the troposphere into the lower stratosphere. Vertical winds in the troposphere and lower stratosphere were strongly modulated for about 6 - 8 hours by each convection event during the period 10 - 11 April 2004. Temporal and spatial structure of momentum flux anomalies showed development from sources located near the middle troposphere. These anomalies developed due to convection-induced gravity waves, and were marginally biased in the meridional direction. Radiosonde observations showed that atmospheric stability and gradual increase in vertical wind shear above convection played a key role in filtering the waves and modifying their vertical wavelength ( similar to 2 km).
