Outline of Final Research Achievements |
Numerical simulations are performed to investigate idealized characteristics of the cloud layers of Jovian planets using two-dimensional settings. In all cases, active moist convection occurs intermittently, and the H2O and CH4 condensation levels act as steady kinematic and compositional boundaries. The mean vertical structure is distinctly different from the hitherto accepted structure based on a one-dimensional thermodynamical model. The intermittent cloud activity is associated with convective instability. The instability accumulates until an appropriate trigger is provided by H2O condensate that falls down through the H2O lifting condensation level. Active cloud development is terminated when the instability is exhausted. The period of intermittency is roughly equal to the time obtained by dividing the mean temperature increase, which is caused by active cumulonimbus development, by the body cooling rate. We also improve our cloud resolving model to treat three-dimensional motion.
