Research Interests

The Earth's climate varies and changes due to its internal processes and external forcing such as human activity and volcanic eruptions. We work on mechanisms and predictions of the climate system and its variability/change by using observational data and numerical simulations. Our interests include:,
1) Dynamics of the climate change
The anthropogenically-induced climate change (i.e. the global warming) exibits seasonality and regionality in temperature changes. Precipitation is projected to increase or decrease dependiong on regions and seasons. We pursue understanding dynamics of the climate changes observed in the past and projected for future.
2) Natural climate variability
Natural climate variability, as well as the climate chage, contributes to abnormal weather events. We study mechanisms and predictions of natural variability in time scales spanning days to decades. Our focus is on (but not limited to) East Asian climate variablity.
3) Intereference of the climate change and natural variability
We recently found that natural variability can influence global-mean climate comparably with the global warming for a decade or two. We re-examine past observations from this perspective, to make suggestions for near-future decadal changes.
