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?)

Climate system, Hydrological cycle in the atmospheric branch, cloud-precipitation climatology, Asian monsoon, snowfall on the Japan Sea side of Japan, Land-atmosphere interaction (soil-precipitation feedback), Urban climatology, Aerosol-cloud inetraction, water vapor variability, global warming, climate change, regional climate model, global climate model, satellite observation (TRMM/GPM), ocean-atmosphere interaction
