Research Field

Multiscale interaction, cloud-resolving, climate model, air-sea coupling, tropical meteorology

Current Research

I work on "reproducing", "understanding", and "predicting" phenomena related with organized convection and/or equatorial waves, with specific interest in multiscale interaction, Air-sea interaction, meridional interaction, and General Circulation. I have put particular emphasis on numerical simulation studies of the Madden-Julian oscillation (MJO), an eastward atmospheric pulse visualized as a gigantic package of clouds, using a global cloud resolving model NICAM and its ocean-coupled version NICOCO.
