Whether this observation imply that the ‘‘North-South” dipolar mode is no-longer applicable to the orbital scale needs to be further addressed using more high-quality precipitation records from both regions. Meanwhile, we also suggest that more attention should be paid to the development of high-resolution precipitation reconstructions since the Last Glacial/Interglacial from South China, which may help to resolve the issue of whether there is a ‘‘tripolar” mode of rainfall changes on various timescales over the eastern China. Such efforts could make a major contribution to our understanding of EASM dynamics, from a paleoclimatological perspective.
