Short summary
In this study, a sodium lidar at the University of Science and Technology of China (USTC) observed multiple sporadic sodium layers (SSLs) and enhanced sodium patterns (ESPs) during a single night. By combining observations from a meteor radar and an ionosonde in Wuhan, the results show that horizontal winds can not only directly transport sodium atoms through advection but also indirectly influence sodium density by modulating ion convergence and Es layers via atmospheric waves.
