Climate System Research Group
Tokyo Metropolitan University

We study regional and global climate systems.

Specific topics are:

Atmospheric hydrological cycle on regional and global scales

Asian monsoon

Cloud and precipitation over the Asian monsoon region

Role of land surface conditions on rainfall characteristics (Land-atmospheric interaction)

Impact of land-use change on regional climate

Tools:

Data analysis (atmospheric circulation (JRA55), satellite derived rainfall and cloud datasets(TRMM/GPM/Himawari), aerosol)

Climate modeling(regional: WRF, global CMIP outputs)

Observations

Key words
(too many?)
