摘要：

The Antarctic climate system fluctuated through glacial-interglacial and millennial-centennial-decadal timescales in the past, closely coupled with other components of the global climate system. Analysis of ice core records offers critical insights on the millennial, centennial and decadal scale climate processes in Antarctica and its tropical linkages. Recent studies have demonstrated that annually-resolved high-resolution ice core records offer the best possible means to understand the quasi-decadal climate variability during the last millennia, when both natural and anthropogenic forcing influenced the climate system. This study discusses the quasi-decadal Antarctic climate variability in response to the solar forcing as well as the decadal to multidecadal climate modes like the Southern Annular Mode, El Nino-Southern Oscillation and the Pacific Decadal Oscillation, with special emphasis on the Indian ice core studies.
