Observational analysis reveals lapse rate tropopause warming in the South Pacific and height changes across regions, indicating climate impact.

Lapse rate tropopause temperature significantly warmed in the South Pacific by over 1 K per decade and shows cooling of up to 1 K per decade in southern high latitudes.
Monitoring of the tropopause provides a global perspective on climate change, utilizing GNSS radio occultation data from 2002 to 2024.
Height changes in the lapse rate tropopause were observed to exceed 200 m per decade over Asia and the Middle East in winter months.
These findings emphasize the interconnected nature of tropospheric and stratospheric changes in the climate system.

Ladstädter et al. (2025) studied this question.
