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.
I welcome new members who are eager to try all available means to
unravel the entangled misterys of the weather & climate system.
(NICAM/NICOCO, climate model MIROC, satellite data,
field observation data, theoretical model, etc.)
