AIPO: KEY SCIENTIFIC ISSUESAIPO: KEY SCIENTIFIC ISSUES

Reveal the characteristics in seasonal to inter-annual Reveal the characteristics in seasonal to inter-annual time scale of the air-sea interaction in the AIPO joining time scale of the air-sea interaction in the AIPO joining area, and propose a theoretical framework about the area, and propose a theoretical framework about the impacts of these processes on the short-term climate impacts of these processes on the short-term climate variation in this area;variation in this area;

Develop a new-generation OGCM and its coupled Develop a new-generation OGCM and its coupled climate model, and propose theories and methods for climate model, and propose theories and methods for improving the prediction of the East Asian climate improving the prediction of the East Asian climate variation on seasonal to interannual scales;variation on seasonal to interannual scales;

Construct a fine spacial resolution ocean data Construct a fine spacial resolution ocean data assimilation system for the AIPO joining area, achieve assimilation system for the AIPO joining area, achieve significant advances in the predictability of ENSO and significant advances in the predictability of ENSO and East Asian monsoon, and also provide a set of high-East Asian monsoon, and also provide a set of high-quality ocean re-analysis data in this area.quality ocean re-analysis data in this area.
