| Abstract | In the equatorial MLT region planetary scale waves play an important role in the dynamics of this region as they act transporting momentum and energy from low to middle and upper atmosphere. The well known quasi-biennial (QBO), semiannual (SAO) and intraseasonal oscillations (ISO) have its generating mechanisms partially associated to the deposition of momentum by equatorial planetary scale waves. Among these, Kelvin waves are of particular interest. Kelvin waves propagate eastward and are characterized by presenting only zonal perturbations. They are observed in three distinct period bands: 10-20 day, 7-10 day and 3-4 day. It is believed that they are generated by convective activity occurring in large scale convective complexes in the troposphere and then propagate upward. Its observed that only 3-4 day Kelvin waves can reach the MLT between 80 and 100 km altitude. Quantifying the momentum transported by this wave and its effects toward the mean flow is then rather important to better understand the dynamic of the region. From a meteor radar installed in the Brazilian equatorial region at São João do Cariri (7.4°S, 36.5°W) tridimensional winds were calculated and used to direct calculating momentum flux transported by 3-4 day equatorial waves. The results show that vertical transport of 3-4 day zonal momentum flux is observed to be as much eastward as westward, but eastward transport is predominant. Largest values of momentum flux are observed near autumn equinox and minima before winter solstice. After winter solstice and during spring, momentum flux exhibits similar behavior. In a single event momentum flux due to 3-4 day wave can reach over 20 m2s-2 and Its magnitudes estimated here are similar to those already reported in the literature. In additional, estimates of mean flow acceleration due to deposition of momentum flux by 3-4 day waves are under way and will be presented and discussed. | |||
