Outline of Final Research Achievements

The atmospheric material circulation on Venus related to cloud formation has been studied by cooperative observations by Akatsuki spacecraft and ground-based telescopes and numerical modeling. We have clarified the structure of the mean meridional circulation and the characteristics of various planetary-scale waves, which may be related to the maintenance of the high-speed zonal flow, by cloud tracking using infrared images covering the whole local time as well as ultraviolet images. We obtained observational clues that angular momentum transport caused by thermal tides contributes to the maintenance of high-speed zonal winds. For integrating observational data with numerical modeling, data assimilation was successfully conducted. The global temperature structure was observed by radio occultation. The cloud physics was introduced into the atmospheric general circulation model, and the distribution of sulfuric acid clouds consistent with the observations was reproduced.

Academic Significance and Societal Importance of the Research Achievements

地球の気候や環境の形成を理解する上で、地球とほぼ同じ大きさの地球型惑星でありながら全く異なる環境を持つ金星と比較することは重要である。この研究では、金星への太陽光入力や大気化学をコントロールする硫酸でできた雲に注目し、探査機と地上望遠鏡を用いて雲形成に関わる大気力学や物質循環の情報を集め、数値モデルとの統合によって気候システムの要素間のフィードバックを明らかにしてきた。このように観測に立脚したメカニズムの探求は、現在の金星気候がどのような平衡状態にあるのかを理解することにとどまらず、地球を含む惑星の気候形成と多様性をもたらす仕組みの解明に資するものである。
