Short summary
Atmospheric drag may vary dramatically under the influence of atmospheric density over aircraft flights at 20–100 km. This indicates that the natural density evolution needs to be analyzed. However, the middle-atmospheric density response to sudden stratospheric warming (SSW) events has rarely been reported. In this study, the density distribution and mass transport process are illustrated based on observation data and global numerical model simulations during the 2021 major SSW event.
