                         measurements was operated at Cachoeira Paulista (22.7degreesS, 
                         45.0degreesW) from September 1998 to August 1999. Dominant gravity 
                         wave events were extracted and studied. It is found that the 
                         horizontal wavelengths are typically from 5 to 60 km and the 
                         period from 5 to 35 minutes with the horizontal phase speed of 1 
                         to 80 m/s. A ray tracing technique was applied in order to find 
                         out the gravity wave sources and to investigate the propagation of 
                         these waves through the atmosphere. The CIRA-86 reference zonal 
                         wind and temperature models and the GSWM-02 tidal wind model were 
                         used as the background condition in the present analysis. The 
                         tidal wind strongly affects the gravity wave propagation and 
                         miss-leads the location of the wave source. The major part of the 
                         tropospheric sources of the gravity waves is located 400 km around 
                         the observation site, and these sources were related with the 
                         lightning activity that is associated with strong tropospheric
