| Outline of Final Research Achievements |
Isotope atmosphere-ocean coupled model has been developed. The simulated results were compared with satellite-based vapor isotope data, and vertical structure and advection process in the atmosphere were investigated. The results indicated that the mid-tropospheric vapor isotope ratio is influenced by re-evaporation of falling droplet inside clouds over western Pacific and Maritime regions. The method for comparing simulated seawater isotope ratio and coral isotope data has been established. It is revealed that simple 1-dimensional mixing model can simulate the interannual and seasonal variations of seawater isotope ratio, but the ocean current and freshwater impact is large in the places close to big river mouths or delta region. Furthermore, isotope data assimilation system has been developed in the first place in the world.
