摘要：

<正> The multi-spatial variability modes of the At-lantic Meridional Overturning Circulation (MOO are iden-tified in the natural coupled simulation of two climate models,the MOC either oscillates at decadal scales with strong cross-equatorial flow or fluctuates locally at interannual scaleswith weaker cross-equatorial flow. Former studies mainlyemphasize the paleo-environmental and paleo-climatic im-pacts of the meridional overturning states transition; thisanalysis indicates the existence of the multi-spatial variabilitymodes of the MOC at interannual to decadal scales. Furtheranalysis indicates that the conventionally used MOC index,which is defined as the maximum zonal mean meridionalstream-function of the North Atlantic, cannot properly de-scribe the multi-spatial variability characteristics of theMOC.
