| Research Abstract |
The aim of this study supported by Grant-in-Aids for Scientific Research(B) is to elucidate the superrotation of Venus by modelling processes of Venus atmosphere. For this purpose, we have successfully developed a radiation model which can correctly represent radiative transfer in the infrared region of Venus atmosphere. The vertical temperature distribution of Venus present atmosphere can be reproduced by this radiation model. By integrating atmospheric general circulation model with this radiation model, the condition of generation of the superrotation is examined. Further, the reproduction experiment of the superrotation is also made by the model with a simplified radiation model ; an critical condition of the generation of the superrotation is elucidated.
