The mechanism of the atmospheric circulation and the transport processes of atmospheric constituents were studied by analyzing observational data taken by Venus Express and ground-based observations. The data were processed using the data analysis softwares developed for the Japanese Venus arbiter Akatsuki, which will be inserted into a Venus orbit in 2015. The analysis revealed various aspects of the atmosphere, such as three-dimensional structures of planetary-scale waves, dissipation of gravity waves at high altitudes, complicated vertical distributions of the upper haze layer, latitudinal and local-time dependence of the cloud height, and long-term variations of the cloud albedo. Numerical simulations, and the observed features were compared with those model results to understand the mechanism. These studies clarified remaining issues to be solved, such as the role of meso-scale processes, chemical processes governing the cloud albedo, and the mechanism of climate variation.

通过分析金星快递和基于地面的观测值分析观察数据，研究了大气循环和大气成分的运输过程的机制。 The data were processed using the data analysis softwares developed for the Japanese Venus arbiter Akatsuki, which will be inserted into a Venus orbit in 2015. The analysis revealed various aspects of the atmosphere, such as three-dimensional structures of planetary-scale waves, dissipation of gravity waves at high altitudes, complicated vertical distributions of the upper haze layer, latitudinal and local-time dependence of the cloud height, and云反照率的长期变化。将数值模拟和观察到的特征与这些模型结果进行了比较，以了解机制。这些研究阐明了要解决的剩余问题，例如中尺度过程的作用，管理云反照率的化学过程以及气候变化的机制。
