The equatorial and low-latitude mesosphere lower thermosphere (MLT) (80-100 km) region of the earth’s atmosphere is pervaded by the atmospheric gravity waves, tides and planetary waves of various spatial and temporal scales. By now, it is well established that the wave driven dynamics is one of the most important processes in the MLT region apart from the dynamics driven by insolation. Thus this region of the atmosphere can be regarded as atmospheric beach as most of the waves deposit their momentum and energy in this part of the atmosphere similar to oceanic waves at shores. However, relative contribution of these waves in shaping the equatorial and low-latitude MLT wind system is one of the most challenging tasks in the realms of middle atmospheric dynamics. In this regard, a study is carried out to using a decade of continuous observations of MLT winds by meteor radar at Thumba (8.5^ON, 77^OE) and Kotatabang (0.2^OS, 100.3^OE) to investigate the mean and variability of MLT wind system. To study the planetary wave activity in the MLT region during the present observational period, time series data of daily averaged zonal and meridional winds are used. The contributions of waves having periods of -2,-5 and -16 days to the variability of MLT wind system are quantified. The present results comprehensively brought out the mean and variability of equatorial and low-latitude MLT wind system and the role of tides, gravity waves and planetary waves in driving them.
