Conclusion (cont)

Static stability 
N^2 of Jupiter in the water condensation layer ranges from 10^-5 for 1 x solar to 10^-4 for 10 x solar; the latter is close to that of the Earth
N^2 of Jupiter's atmosphere is about 10 times as large as those of the other Jovian planet atmospheres because of its large gravity 
For Uranus and Neptune, N^2 of CH4 condensation layer is larger than that of H2O, since H2O condensation layer is located in the deeper region and H2O mixing ratio per unit mass dry air (g/kg) is small
