根据热带印度洋长时间序列观测资料 ,分析了热带印度洋存在的年代际尺度的海洋变率 ;揭示强烈的年际尺度海洋异常事件能够深及热带印度洋的季节性温跃层 ,随之维持长达1～ 2a的记忆 .初步探讨了一种针对热带印度洋年代际海洋变率的动力学解释 ,即不规则的强烈的年际海洋异常事件能够经过其记忆过程的过滤沉淀 ,而形成年代际尺度的一类缓变的气候背景
Based on the long time series observations of the tropical Indian Ocean, the decadal-scale ocean variability in the tropical Indian Ocean is analyzed. It is revealed that the strong anomalous ocean anomalies can deeply affect the seasonal warming of the tropical Indian Ocean and maintain up to 1 ~ 2a. A kinetic explanation of the interdecadal ocean variability in the tropical Indian Ocean has been discussed tentatively, ie, the irregular and intense intertidal marine anomalies can undergo filtration and sedimentation in their memory processes to form a decadal scale Gradient climatic background
