Abstract

In this study, MRI-AGCM 3.2 S (20km resolution) was used to assess the uncertainty of changes in land hydrological quantities due to climate change. 4 different future climate scenarios were generated for RCP8.5 using different SST change patterns (SST ensemble) in the Program for Risk Information on Climate Change (SOUSEI). Land surface model SiBUC was used to calculate surface energy and water balance, then distributed hydrological model Hydro-BEAM was used to calculate river discharge. Evapotranspiration increased almost in all models in Japan, but some of them have been on a downward trend, especially concentrated in the coastal areas of the Chugoku and Shikoku regions.I think that land use and soil differences are affecting, so we will investigate further the change in the amount of evapotranspiration for each land use.
