Research interests

We research atmospheric circulations and their role in climate changes.

Our goal is to elucidate physical mechanisms underlying the response of atmospheric circulations, surface temperature and precipitation, and tropical cyclones to changes in radiative forcing. Systematic experimentation with numerical climate models allows us to develop climate theories that encompass not only Earth's current and future climate, but also the broader range of possible climates. A few illustrative examples of this research are described here.
