Abstract Using COSMIC-2 and METOP radio occultation measurements during the years 2020 and 2021, the study presents the first direct and independent relationship between the potential energy (E p ) in the stratosphere, precipitable water vapour (PWV), tropopause heights (TPH), and cold-point heights (CPH) over South America. 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 $${20}^{o}N - {10}^{o}N$$ 20oN-10oN in 2020 and 2021. Our result demonstrated the possibility that convective activity was a major driver of the tropical gravity waves over South America. In the subtropical (30 $$^circ$$ ∘ –40 $$^circ$$ ∘ ) region, especially in the winter, the tropospheric parameters make little or no contribution to gravity wave activity in the region. 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. Graphical Abstract
利用COSMIC-2和METOP在2020年和2021年的射电掩星测量数据，研究首次揭示了南美洲平流层势能(E p)、可降水量(PWV)、对流层顶高度(TPH)和冷点高度(CPH)之间的直接独立关系。南美洲大陆包括热带地区、安第斯山脉和中纬度气候。利用平流层重力波(SGW)势能(E p)、PWV和对流层顶参数高度(TPH和CPH)的季节平均值，探讨了平流层重力波(SGW) E p与对流层参数(PWV、TPH和CPH)的关系。在东部的安第斯山脉周围，水蒸气明显减少(PWV ＆lt;10 mm)和相对较高的重力波exp (exp ＆gt;8kj kg−1)。在热带地区(±20°)夏季，PWV与较低的SGW E p之间存在较好的相关性。总体而言，2020年和2021年夏季和春季呈较好的强相关，冬季呈负相关或不相关。此外，在2020年和2021年$${20}^{o}N - {10}^{o}N$$ 20 o N - 10 o N夏季，观测到SGW、PWV和TPH之间存在良好且强的相关性。我们的结果表明，对流活动可能是南美洲热带重力波的主要驱动因素。在亚热带(30 $$^circ$$ -40 $$^circ$$°)地区，特别是在冬季，对流层参数对该地区的重力波活动贡献很小或没有贡献。CPH在南美洲热带上空与SGW呈正/负关系。热带SGW活动对对流层顶参数的结构产生影响，这可能是该地区对流活动的结果。图形摘要
