Short summary
The factors behind why some polar stratospheric wind disturbances persist while others remain short are unclear. This study examines the impact of tropospheric high-pressure systems on the duration of three recent polar stratospheric wind disturbances in the winter of 2023/24. Two were short-lived, lasting under 7 d. The findings in this study show that two short disturbances could not develop into long-lasting events due to developing high-pressure systems over the planetary wave troughs.
