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

  • 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?)
