Research Interests:

In our solar system, there are a lot of planets and satellites that have atmospheres. In those atmospheres, the circulation structure differs in various ways. I am studying the planetary atmospheres to understand physical mechanisms resulting in such diversity. Now, I am mainly working on high resolution simulations of atmospheres of Mars and the Earth, and development of planetary atmosphere general circulation model.
