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 |
