伊勢湾の水文環境への温暖化影響について

Abstract

For the purpose of an integrated watershed environment management, a coupled river runoff and ocean circulation model is developed. Climate change impact on the hydrologic environment of Ise Bay is assessed by the model. Future climate change of rain fall amount and air temperature from 15 CMIP3 models are used as an atmospheric boundary conditions, and climate change of river discharge and water temperature from Hydro-BEAM prediction are also used as a river mouth boundary condition. Future SST in Ise Bay increases by about 3℃ in August, while 2℃ in February. Coastal areas are more strongly influenced.
