Fig. 2From: Stratospheric gravity wave potential energy and tropospheric parameters relationships over South America: a study using COSMIC-2 and METOP radio occultation measurementsSeasonal variation of Ep over South America using COSMIC-2 measurements in 2020. The seasonal variation of Ep at 20–30 km, 30–40 km, and 40–50 km are shown at the top, middle, and bottom row, respectively. Each panel has its corresponding labeling at the top. Each row has a corresponding color barBack to article page
