The South American continent comprises the tropical region, the Andes Mountain range, and mid-latitude climates. The seasonal mean of the potential energy (E p ), the PWV, and the tropopause parameters height (TPH and CPH) were obtained to investigate the relationship between the stratospheric gravity wave (SGW) E p and the tropospheric parameters (PWV, TPH, and CPH). Around the Andes Mountains to the east, there is significantly less water vapour (PWV < 10 mm) and a relatively high gravity wave E p (E p > 8 kJ kg − 1 ). A good correlation of variability was found between the PWV and the lower SGW E p in summer over the tropical region (± 20 ◦ ). Generally, good and strong correlations were observed in the summer and spring, with negative/no correlations in the winter in 2020 and 2021. Also, good and strong correlations between SGW, PWV, and TPH were observed in the summer at $${20}^{o}N - {10}^{o}N$$ <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"> <mml:mrow> <mml:msup> <mml:mrow> <mml:mn>20</mml:mn> </mml:mrow> <mml:mi>o</mml:mi> </mml:msup> <mml:mi>N</mml:mi> <mml:mo>-</mml:mo> <mml:msup> <mml:mrow> <mml:mn>10</mml:mn> </mml:mrow> <mml:mi>o</mml:mi> </mml:msup> <mml:mi>N</mml:mi> </mml:mrow> </mml:math> in 2020 and 2021.

The CPH generally showed a no/negative with SGW over the South American tropics. The SGW activities in the tropical region showed an impact on the structure of the tropopause parameters, which could be a result of the convective activity in this region.
