| Abstract | Using the variance in meteor radar winds as a measure of gravity wave intensity, we investigate the temporal variations in gravity wave activity at three locations in Brazil: São João do Cariri (7.3 S, 36.4 W), Cachoeira Paulista (22.7 S, 45.0 W) and Santa Maria (29.7 S, 53.7 W). The technique used is that of Hocking (2005) which makes it possible to separate the zonal and meridional components of the fluctuating wind velocity. We find that the seasonal variation of the fluctuating wind is similar to that of the amplitude of the diurnal tide, showing a predominantly semi-annual variation, stronger at Cachoeira Paulista and Santa Mara than at the quasi-equatorial station, Cariri. Both with respect to the seasonal trend and shorter term variations, strong coupling between gravity wave activity and tides is indicated by a remarkably close correlation between the fluctuating velocity and the vertical shear in the tidal winds. This coupling suggests that tidal wind shear might be an important in situ source of gravity waves in the mesopause region. |
