Abstract
An atmospheric general circulation model (AGCM) for Venus is being developed on the basis of AFES (AGCM For the Earth Simulator) in order to study atmospheric phenomena of Venus by the numerical simulation with high resolution. Super-rotation is assumed to exist at initial state and to be maintained by the relaxation forcing due to the meridional temperature gradient. In the time evolution of this setting, baroclinic modes grow in the cloud layer with small static stability. The structures of unstable modes are similar to those obtained in the linear stability analysis initially, but changed by the nonlinear interactions in the later stage. Meridional transport of momentum and heat by these unstable inodes is discussed.
