Ice-ocean coupled system, Circulation of the Antarctic Ocean and Okhotsk Sea.
Atsushi Kubokawa
My research interest is in theoretical aspects of the Geophysical and/or Oceanographic Fluid Dynamics. I have studied frontal wave dynamics, nonlinear evolution of baroclinic jets, outflow from a sea strait, etc., and currently, I am studying oceanic gyre structure based on the ventilated thermocline theory.
Youichi Tanimoto
A basin-scale sea surface temperature is one of the important climate variables because the ocean thermal condition could control the long-term fluctuations in the atmospheric general circulation. However since the atmospheric response to the ocean is not uniform among all ocean domains, we should know the actual status of the air-sea heat exchange with high accuracy. To do that, we made a quality-controlled data set of heat fluxes for the global ocean, and examined the spectral and spatial structures of the large-scale ocean-atmosphere interaction. I believe that this work will help to improve the flux adjustment in the ocean- atmosphere coupled climate models. Furthermore, the feedback from the numerical simulation could give a better diagnosis of the present and past global changes.

Masakazu Yoshimori
(Assoc Prof)
My research aims to establish unified "theories" which explain climate changes in the past and the future in a consistent manner using primarily numerical, global climate models. I investigate interactions of various physical processes, rather than focusing on a specific process in depth, in order to understand mechanisms of the climate changes. Research interests include recent Arctic warming and paleoclimate.
Tomohiro Nakamura
He aims at clarifying the interaction among atmosphere, ocean, land, and sea-ice in a Pan Okhotsk region. Also interested in are the tidal processes around the Kuril islands (generation of internal waves and mean flow) and their impacts on the formation of water masses in the North Pacific Ocean.
Masayuki Kawasima
(Assis Prof)
My research interests focus on the dynamics of mesoscale cloud systems (squall line, frontal rainband, etc.). Currently, I am studying the interaction between these systems and large scale phenomena using non-hydrostatic cloud model.
Takenobu Toyota
(Assis Prof)
My major interest is to understand the formation and melting processes of sea ice on the sub-grid scale especially in the seasonal ice zone. I am approaching this theme mainly from in-situ observation and laboratory experiment.
Yoshimasa Matsumura
(Assis Prof)
Physical oceanography, numerical modeling of small scale ocean processes and ice-ocean coupled system, high-performance computing.
Genta Mizuta
(Assis Prof)
I research on the dynamical structure that keeps the large-scale circuration on the ocean,using simple numerical models. I have studied at theoretically that the effect of idealized geography of ocean bottms on the deep layer circulations. And recently I've interested in the research of the ocean circulation using the observational methods.
