| Abstract | Planetary scale waves in equatorial region transport a significant amount of energy and momentum through atmosphere. Quantifying the momentum transported by these waves and its effects toward the mean flow is rather important. Direct estimative of the momentum flux transported by these waves requires horizontal and vertical wind measurements. Ground-based meteor radars have provided continuous and reliable measurements of the horizontal wind components in the MLT region. On the other hand, vertical wind component does not present the same reliability. However, an approach presented by Babu et al. (2012), made possible to calculate tridimensional daily winds by using only near zenith echoes detected around their maximum counting rate, i.e., during early morning hours. From daily tridimensional winds, momentum fluxes due to planetary scale waves can be estimated. Following this approach, we have used measurements performed by a meteor radar installed at São João do Cariri (7.4ºS; 36.5ºW) in order to measure vertical winds and after determine the momentum flux transported by these waves. Vertical wind presents magnitudes of a few meters per second and occasionally reaches magnitudes higher than 10 m/s. Below 92 km vertical wind is upward during the whole year and above exhibits a semi-annual oscillation with downward phase during the equinoxes. Variations associated to planetary scale waves in the vertical wind are also observed and some of them appear simultaneously in the zonal and meridional wind. Vertical transport of zonal momentum fluxes of 3-4 day component is found to be maximum near autumn equinox, when its value reaches almost 20 m2s -2, while minimum momentum fluxes were observed before winter solstice. | |||
