影响我国短期气候异常的关键区：亚印太交汇区

围绕国家重点基础研究发展计划项目“亚印太交汇区海气相互作用及其对我国短期气候的影响”，介绍了“亚印太交汇区”（AIPO）的概念，从气候系统多圈层相互作用的角度，阐述了研究AIPO区海气相互作用的科学意义；在分析国内外海气相互作用影响气候研究发展动态的基础上，指出AIPO区是影响我国短期气候的关键区；研究AIPO区海气相互作用对我国短期气候的影响也是国民经济发展需要亟待解决的重要课题。介绍了项目拟研究的关键科学问题，指出该项目的最终研究目标为：揭示AIPO季节到年际尺度的海气相互作用特征，从而提出该关键区海气相互作用影响我国短期气候异常的理论框架，为改进东亚季风的季度—年际变化预测提供理论和方法。

The Key Region Affecting the Short-term Climate Variations in China: The Joining Area of Asia and Indian-Pacific Ocean

Based on the National Basic Key Research Program(973)"Ocean-Atmosphere Interaction over the Joining Area of Asia and Indian-Pacific Ocean(AIPO) and Its Impact on the Short-term Climate Variation in China",this paper introduces the definition of the "Joining Area of Asia and Indian-Pacific Ocean(AIPO)";highlights the scientific significances for investigating the air-sea interactions in AIPO area from the view point of multi-level interactions in the climate system;and stresses why AIPO is a key area for the shortterm climate variation and prediction in China.This program is also an important subject that meets the urgent needs of the national economy.Several key scientific issues are then emphasized.Finally the basic scientific objectives of this program are listed,which are: to reveal the characteristics of air-sea interaction in the AIPO joining area on seasonal to inter-annual time scales;to propose a theoretical framework about the impacts of these processes on the short-term climate variation in this area;and to provide theories and methods for improving the East Asian climate prediction on seasonal to inter-annual scales.
