Resumo
The tropopause, a fundamental boundary between the troposphere and stratosphere, serves as a
crucial indicator of atmospheric stability, influencing the distribution of key trace gases. This paper
offers a comprehensive decade-long analysis (2013-2023) of tropopause height variations over
São Paulo, examining two distinct definitions: the Cold Point Tropopause (CPT) and the Lapse Rate
Tropopause (LRT).
Utilizing Radiosonde data to capture vertical profiles of temperature and pressure, our algorithm
calculates both CPT and LRT, illustrating their evolution over time. This analysis enables the exploration
of seasonal, interannual, and long-term trends, providing valuable insights into the region's atmospheric
stability and potential correlations between tropopause variations and significant meteorological
events.
The results underscore the algorithm's efficiency in extracting tropopause heights from radiosonde
data,
elucidating the strengths and limitations of both CPT and LRT definitions. Additionally, the findings
shed light on the region's climate patterns, offering a foundation for future atmospheric sciences and
climate research.
