| Outline of Final Research Achievements |
The core of climate change research is Global Climate Model (GCM) and its improvement is important. This study developed the ocean wave coupled GCM and estimated the contribution of waves to global climate system. Implementing the wave dependent air-sea momentum flux into the wave coupled GCM, we showed that the wave coupling can improve the reproducibility of historical ocean heat content which control the sea level rise and atmospheric temperature increase. And, the ocean wave coupling can influence the typhoon track in mid-latitudes. These results indicate the importance considering wave effects in climate modeling.
