Outline of Final Research Achievements

Though coastal seas have specific characteristics under the influence of the land, they change in a close relation to open oceans through water exchange. In this study, a novel high-resolution ocean model is developed to focus on water exchange processes around Japan. The model simulates water exchange induced by various kinds of motion with a horizontal scale of 10-1000 km, though the activities vary significantly at each location. Based on the model results, a comprehensive quantitative evaluation is for the first time made about water exchange in the entire coastal regions around Japan. This achievement is expected to be useful as basic data for monitoring and prediction of water quality environment and impacts of climate change in the coastal seas of Japan.
