Formation and evolution of nighttime MSTID modulated by the atmospheric tides

In this report, we utilize data from the multi-ground-based instruments of the Chinese Meridian Project (CMP) and public national websites, including red-line all-sky airglow imagers, digisondes, GNSS-TEC receivers, and so on, to conduct an in-depth investigation into the formation and evolution processes as well as the accompanying physical mechanisms of two nighttime MSTID events occurring over the mid- and low-latitude regions of China. Specifically, we focus on the impacts of the hourly tidal-induced atmospheric dynamo process and its modulation effect on ionospheric electron density (airglow), which in turn affect the formation and evolution of these nighttime MSTIDs. The specific physical processes associated with the nighttime MSTIDs are discussed.
