Abstract

Tropopause Fold (TF) is a significant atmospheric phenomenon in the upper troposphere and lower stratosphere (UTLS) in mid-latitudes, with critical implications for weather, climate, and particularly aviation safety, especially over the Tibetan Plateau. This study investigates the distribution characteristics of TF and its relationship with Clear Air Turbulence (CAT) in the Tibetan Plateau region using reanalysis data and aircraft observations. Results indicate that the occurrence frequency of TF is highest in winter and lowest in summer. The spatial distribution of TF shows a zonal pattern across all seasons. In winter, high-frequency TF zones are located over the Tibetan Plateau around ~ 30°N, while in summer, the high-frequency zones shift southward to the southern edge of the plateau. The occurrence frequency of TF-related CAT is significantly higher in winter than in other seasons, with the affected areas primarily located west of the Hengduan Mountains. The greater the depth of the fold, the stronger the aircraft turbulence.
