Fig. 10From: Stratospheric gravity wave potential energy and tropospheric parameters relationships over South America: a study using COSMIC-2 and METOP radio occultation measurementsThe seasonal relationship between the latitudinal mean normalized Ep distribution (blue line) and the water vapour (PWV) (red line) with the error bars for 20◦S–30◦S, and 30◦S–40◦S. Each panel shows the mean Ep distribution and the PWV at 20–30 km altitudeBack to article page
