The National Basic Research Program of China /973 Program Ocean-Atmosphere Interaction over the Joining Area of Asia and Indian-Pacific Ocean (AIPO) and Its Impact on the Short-Term Climate Variation in ChinaOcean-Atmosphere Interaction over the Joining Area of Asia and Indian-Pacific Ocean (AIPO) and Its Impact on the Short-Term Climate Variation in China Period: Period:

The theme of the program is to identify the characteristics, patterns, and causes of air-sea interactions over the AIPO joining area and the intrinsic mechanisms of their impacts on the short-term climate anomalies over China. AIPO: KEY SCIENTIFIC ISSUES

 Reveal the characteristics in seasonal to inter-annual time scale of the air-sea interaction in the AIPO joining area, and propose a theoretical framework about the impacts of these processes on the short-term climate variation in this area;  Develop a new-generation OGCM and its coupled climate model, and propose theories and methods for improving the prediction of the East Asian climate variation on seasonal to interannual scales;  Construct a fine spacial resolution ocean data assimilation system for the AIPO joining area, achieve significant advances in the predictability of ENSO and East Asian monsoon, and also provide a set of high- quality ocean re-analysis data in this area. AIPO: Specified Objectives
