Simulation of Venusian atmosphere by AFES (Atmospheric general circulation model For the Earth Simulator)
Abstract
We have developed an atmospheric general circulation model (AGCM) for Venus on the basis of AFES (AGCM For the Earth Simulator) and performed a very high -resolution simulation. A superrotation consistent with observations is reproduced with a realistic solar heating. Baroclinic waves appear in a weakly stratified layer with large vertical shear of the basic zonal flow at the cloud level. Rossby and Kelvin waves generated in the model are consistent with observations. Furthermore,a realistic polar cold collar is reproduced in the polar region.Spectral analyses of the horizontal kinetic energy are also performed in the results with a high-resolution simulation (T159L120).
