As in Fig. 3, except that H = 8 and k = 5. The diminished energy-carrying capacity of both the surface modes and the high-order body modes when the lid of the atmosphere is made larger and when higher radial resolution modes are considered. The energy of the low-order body modes, especially the FCM, FBM and the first overtone corrugation mode remain unchanged compared to their energies for lower values of H, depicted in the two previous figures.
