Fig. 8: The 24 h backward trajectory and the air temperature change along the path.

a The 24 h backward trajectory of air mass involved in the 2020 event. The star marker (Point C) is the station. The blue circle (Point B/A) is air mass at 12 UTC with a distance of the Rossby radius of deformation to the mountain. b The air temperature (K) along the path. The star marker and blue circle indicate the same points as those in (a).
