英文摘要	We report a lower thermospheric-enhanced sodium layer (TeSL) case observed at Yanqing station in Beijing, China (116. 0 degrees E,40. 5 degrees N) on 26 May 2011. From starting to collect data to the end of the observation, the density of lower thermospheric sodium layer was constantly enhanced. Its peak density increased from 250 cm(-3) to 1500 cm(-3). However, its peak height decreased from 111 km to 100 km gradually. At the same time, an ionosonde away from 28 km detected a Es layer in 106 km to 117 km, The average intensity of the Es layer was 4. 5 MHz. According to the observational data of meteor radar, we fitted zonal wind over 100 km, and found the wind shear node decreased from 122 km to 108 km. The evolution trend of the Es layer and zonal wind were similar to the TeSL. We calculated vertical velocity of ions and the production rate of radiative recombination, and explained the density and height of the sodium atoms. We speculate the Na+ converged by wind shear mechanism. Furthermore, the thermospheric sodium layers are neutralized from converged Na+ layers.
