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.

Atmospheric layers called the middle atmosphere exist above the troposphere, where daily weather changes occur. The importance of the middle atmosphere for seasonal forecasting and climate change has been well recognized recently. We have investigated the dynamical processes in the troposphere and middle atmosphere by combining our numerical experiments, experimental data from climate multi-models in the world, and various observational data. We try to advance our knowledge of physical processes of various phenomena by considering the ocean, troposphere, and middle atmosphere as a single system.

The ocean and atmosphere are coupling and the interaction can be an important feature in the earth environmental system. An essential part of this interaction is air-sea flux (or surface flux), i.e., the heat and momentum exchange, as well as exchanges of substances such as water and gas between the ocean and the atmosphere. We will investigate to understand air-sea interaction phenomena by making full use of satellite remote-sensing technology that observationally estimates global surface fluxes.
Teppei J. Yasunari
(Assoc Prof)
I've worked mostly on atmospheric aerosols, glaciology, climate, and meteorology related researches in the field of environmental science by means of observation, modeling, and data analysis. My main interests are especially light-absorbing aerosols such as dust, black carbon, and organic carbon, and their impacts on air pollution (aerosols and PM2.5), climate, and interactions with snow and environment. Recently, I have worked more on the Arctic region, especially for wildfires, and their causes and impacts on air quality. The long-term target in my future research would also be wildfire related researches in/around the Arctic, its air pollutions, and its causes and climate impacts, which would be essential for these better future projections and its assessment.
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

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.

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.
Yoshihiro Nakayama

Polar Oceanography in the Southern Ocean. Especially interested in (1) ocean circulation and dynamics in high latitudes, (2) ice shelf-ocean interaction, (3) numerical modeling, and (4) in-situ observations.
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.
Takuro Matsuta
(Assis Prof)
My research focuses on polar and mid-latitude ocean circulations with the aim of understanding the response of the climate system to climate variability and climate change. In particular, I am interested in eddy-mean flow interactions in the Antarctic Circumpolar Current using geophysical fluid dynamics theories, numerical simulations, and data analysis. I am also interested in the application of mathematical physics to problems in atmospheric and oceanographic sciences.
