Optimal minimization method of Gibbs free energy which developed by Sugiyama et al. (2001) is utilized to obtain equilibrium compositions in order to cover a variety of basic elements. It is shown that CH4 is the most dominant contributor in producing a stable layer in the Uranian atmosphere. In the cloud layer of the Jovian atmosphere, the proportional law of static stability to H2O mole fraction, which is assumed by Achterberg and Ingersoll (1989), does not hold when the H2O mole fraction is larger than about 5 x solar. The value of static stability obtained for the Jovian cloud layer is too small to explain the phase velocity of the SL9 (Shoemaker-Levy 9) impact wave as that of an internal gravity wave., 資料番号: AA0063350037}, pages = {135--138}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Static stability of the cloud layers of the Jovian atmospheres estimated from the moist adiabatic profiles}, year = {2006} }
