                         Paulista, Brazil (22.7°S, 45.0°W), between April 1999 and April 
                         2004 have been used to investigate the planetary-scale 16-day 
                         wave. Spectral analysis shows the presence of bursts in the 12- to 
                         20-day period range, mainly in the zonal component, with 
                         enhancements observed during all seasons. The 16-day wave exhibits 
                         year-to-year variability, but did not exhibit a clear seasonal 
                         behavior. This study reveals that the 16-day wave at 22.7°S was 
                         strongest during austral autumnwinter seasons for the years 2002 
                         and 2003, whilst for 19992000, 20002001 and 20022003 16-day wave 
                         was strongest during springsummer seasons. The 16-day wave 
                         activity was observed during both winter and summer months over 
                         Cachoeira Paulista, and the enhancements seen for summer seasons 
                         reinforce the interpretation of inter-hemispheric penetration. 
                         During the most intense events in the zonal component, the 
                         vertical structure revealed maximum amplitudes of about 14 m/s at 
                         90 km and above and, the vertical phase structure showed 
                         descending phase with vertical wavelengths of about 51 ± 11 km.",
