Research Abstract

For the purpose of investigating the interplay among dynamical, thermal, and compositional structures of the atmospheres of Jovian planets, we compiled the current status of corresponding knowledge, developed a hierarchical modeling system, and conducted numerical experiments with those hierardical modeling systems. The main findings of our investigations are summarized as follows:
1. We developed a vertical one-dimensional equilibrium cloud condensation model, which enable us to cover possible atmospheric compositional varieties of the Jovian planets. We found that the contributions to the intensity of stability by the cloud layers associated with the condensation of NH_3 and formation of NH_4SH are not negligible compared with that of H_2O.
2. We developed a two-dimensional cloud convection model incorporating the condensation of NH_3 and H_2O and formation of NH_4SH. We conducted a series of numerical experiments, and found that the H_2O condensation level acts as a distinct dynamical … More boundary that separates the convective motions above and below it. The stable layers due to NH_3 and NH_4SH clouds cannot suppress the cloudy plumes driven by H_2O condensation healing, resulting in the mixing over the full depth of the atmosphere above the H_2O condensation level.
3. With the application to the Jovian atmosphere in mind, we performed a series of numerical studies on the equatorial acceleration using the three dimensional Bousinesq spherical shell convection model. We found that a strong stable layer in the outer layer helps the development of equatorial retrograde jet. This result may raise a question about the theory where rotating spherical thermal convection explains the cause of the equatorial westerly jets of Jupiter and Saturn.
4. A common software infrastructure, over which those numerical models were constructed, was developed. It contains "gt4f90io" which is a library for I/O of numerical data, and "Rdoc" which is an automatic documentation generator for numerical model codes. We also organized a standard style of Fortran90 programming and constructed a library of Fortran90 functions for basic mathematical manipulations, with which we developed 'Spmodel" which is a set of spectral models. All of the softwares mentioned are open to public on our web site. Less
