Abstract

We developed a high-resolution, Coupled Atmosphere-Ocean Regional Climate Model to project climate change over Japan with more sophisticated atmosphere-ocean interaction. The model represented sea surface temperature (SST) distribution well. An SST bias over the Japan Sea was improved by 10 to 20% compared to a non-coupled ocean model driven by atmospheric forcing in a GCM. These results indicate that realistic, high-resolution atmospheric conditions positively impact on the reproduction and projection of oceanic conditions.
SST in the future projection simulation was 1 to 6°C warmer than in the present climate run. A particularly remarkable warming signal was projected to the sea east of Hokkaido in both summer and winter. The model also simulated cooling SST off Sanriku (143E/39N) in winter, which has never obtained by non-coupled ocean model. These projected SST results are likely to be related to future changes in surface wind.
